WBPSC Prelims Complete Test-24

The correct answer is B. Frequency.

Frequency is the number of waves that pass a given point in a given amount of time. It is measured in Hertz (Hz), which is equal to one wave per second. The higher the frequency, the higher the pitch of the sound.

Velocity is the speed of a wave. It is measured in meters per second (m/s). The velocity of a sound wave depends on the medium through which it is traveling. For example, sound travels faster through air than through water.

Displacement is the distance from a point's rest position to its current position. It is measured in meters (m). Displacement is a vector quantity, which means it has both magnitude and direction.

Acceleration is the rate of change of velocity. It is measured in meters per second squared (m/s^2). The acceleration of a sound wave is zero, because the velocity of a sound wave does not change.

The correct answer is: A. Decreases with light doping.

The depletion layer is a region at the junction of a P-type and N-type semiconductor where there are no free charge carriers. The width of the depletion layer depends on the doping concentration of the P-type and N-type semiconductors. The higher the doping concentration, the narrower the depletion layer. This is because the higher doping concentration results in a higher concentration of free charge carriers in the P-type and N-type semiconductors, which reduces the electric field at the junction and hence the width of the depletion layer.

Option B is incorrect because the depletion layer increases with heavy doping.

Option C is incorrect because the width of the depletion layer is not independent of applied voltage. The applied voltage affects the electric field at the junction, which in turn affects the width of the depletion layer.

Option D is incorrect because the depletion layer is decreased under reverse bias.

Equity share capital is a type of ownership interest in a company. When a company issues equity shares, it is essentially selling a piece of itself to investors. Equity shareholders are the owners of the company and have the right to vote on important matters, such as the election of directors. They also have the right to receive a share of the company's profits, if any.

Debentures are loans that companies issue to raise money. Debenture holders are creditors of the company, and they have the right to be repaid the principal amount of the loan, plus interest, on a specified date. Debentures are typically considered to be a more secure form of investment than equity shares, as they have a higher priority claim on the company's assets in the event of liquidation.

Preference share capital is a type of ownership interest in a company that ranks above equity shares in terms of priority of payment. Preference shareholders are entitled to receive a fixed dividend, which is paid before any dividends are paid to equity shareholders. They also have the right to be repaid the principal amount of their investment, if any, before equity shareholders in the event of liquidation.

All three of these sources of finance can be used to raise long-term funds for a company. The choice of which source to use will depend on a number of factors, such as the company's financial situation, its investment objectives, and the cost of each type of finance.

The correct answer is $boxed{frac{{16}}{{32}}}$.

The probability of getting at least one head is the complement of the probability of getting no heads. The probability of getting no heads is the probability of getting tails all five times. This is $frac{1}{2}timesfrac{1}{2}timesfrac{1}{2}timesfrac{1}{2}timesfrac{1}{2} = frac{1}{32}$. Therefore, the probability of getting at least one head is $1 - frac{1}{32} = boxed{frac{{16}}{{32}}}$.

Each option can be explained as follows:

• Option A: $frac{1}{{32}}$ is the probability of getting all tails. This is a very unlikely event, so it is not the correct answer.
• Option B: $frac{{13}}{{32}}$ is the probability of getting exactly one head. This is possible, but it is not as likely as getting at least one head. Therefore, it is not the correct answer.
• Option C: $frac{{16}}{{32}}$ is the probability of getting at least one head. This is the correct answer.
• Option D: $frac{{31}}{{32}}$ is the probability of getting all heads. This is a very unlikely event, so it is not the correct answer.

The correct answer is C. 9.45 kilocalories.

One gram of fat contains 9.45 kilocalories of energy. This is more than twice the amount of energy contained in one gram of carbohydrates or protein, which is 4.18 kilocalories. The reason for this is that fat is a more concentrated form of energy. It is made up of long chains of carbon and hydrogen atoms, which are packed together very tightly. When these chains are broken down, they release a lot of energy.

Fat is an important source of energy for the body. It is also a good source of essential fatty acids, which are necessary for the proper functioning of the body. However, it is important to eat a healthy balance of fat, carbohydrates, and protein. Too much fat can lead to weight gain and other health problems.

The other options are incorrect because they do not represent the correct number of kilocalories of energy released from one gram of fat.

The correct answer is: D. 31 May.

World No Tobacco Day is observed on 31 May every year. It is an annual observance that encourages a 24-hour cessation of tobacco use. The day is intended to draw attention to the harmful and deadly effects of tobacco use and to discourage the use of tobacco in any form.

The day was first observed in 1987, following the adoption of the World Health Organization's Framework Convention on Tobacco Control in 2003. The convention calls on all member states to implement a comprehensive tobacco control program, including measures to reduce tobacco use, protect people from secondhand smoke, and raise taxes on tobacco products.

Tobacco use is the leading cause of preventable death in the world. It is responsible for more than 7 million deaths each year, including more than 890,000 deaths from secondhand smoke exposure. Tobacco use is a major risk factor for a number of chronic diseases, including cancer, heart disease, stroke, and chronic obstructive pulmonary disease (COPD).

World No Tobacco Day is an opportunity to raise awareness about the dangers of tobacco use and to encourage people to quit smoking. It is also a time to call on governments to take action to reduce tobacco use and protect people from secondhand smoke.

The other options are incorrect because they are not the dates on which World No Tobacco Day is observed.

The correct answer is $boxed{frac{{{{text{e}}^4}}}{{4!}}}$.

The Taylor series expansion of $f(x)$ about $x=a$ is given by

$$f(x) = sum_{n=0}^{infty} frac{{{f}^{(n)}}(a){{(x - a)}^n}}{{n!}}$$

where $f^{(n)}(x)$ is the $n$th derivative of $f(x)$.

In this case, $f(x) = {e^x}$ and $a=2$. Therefore, the Taylor series expansion of $e^x$ about $x=2$ is given by

$$e^x = sum_{n=0}^{infty} frac{{e^{(n)}}(2){{(x - 2)}^n}}{{n!}}$$

The fourth derivative of $e^x$ is $e^x$. Therefore, the coefficient of $(x-2)^4$ is $frac{{e^4}}{{4!}} = boxed{frac{{{{text{e}}^4}}}{{4!}}}$.

The other options are incorrect because they do not correspond to the coefficient of $(x-2)^4$ in the Taylor series expansion of $e^x$ about $x=2$.

The correct answer is: A. Decade to Roll Back Malaria in Developing Countries, Particularly in Africa

The United Nations declared 2003-2012 as the International Decade to Roll Back Malaria in Developing Countries, Particularly in Africa.

The decade was a success, with malaria deaths declining by 60% and malaria cases declining by 50% between 2000 and 2015.

The other options are incorrect. Option B is incorrect because the First International Decade of the World's Indigenous People was 1995-2004. Option C is incorrect because the First United Nations Decade for the Eradication of Poverty was 1990-1999. Option D is incorrect because the United Nations Literacy Decade was 1990-1999.

The correct answer is D. vacuum.

Light travels at the fastest speed in a vacuum, which is 299,792,458 meters per second. This is the speed of light in a vacuum, and it is the fastest speed at which any information can travel in the universe.

Light travels slower in other materials, such as glass, water, and hydrogen. This is because the light waves interact with the atoms and molecules in the material, which slows them down.

The speed of light in a material is given by the equation $v = frac{c}{n}$, where $c$ is the speed of light in a vacuum and $n$ is the refractive index of the material. The refractive index is a measure of how much light slows down in the material.

The refractive index of glass is 1.52, the refractive index of water is 1.33, and the refractive index of hydrogen is 1.41. This means that light travels 1.52 times slower in glass than in a vacuum, 1.33 times slower in water than in a vacuum, and 1.41 times slower in hydrogen than in a vacuum.

The correct answer is (d), Chile.

Ecuador, Colombia, and Brazil are all major coffee producing countries. Ecuador is the 10th largest coffee producer in the world, Colombia is the 3rd largest, and Brazil is the largest. Chile, on the other hand, is not a major coffee producer. It only produces a small amount of coffee, and it is not a significant player in the global coffee market.

There are a few reasons why Chile is not a major coffee producer. First, the climate in Chile is not ideal for coffee cultivation. Coffee plants need a warm, humid climate, and Chile's climate is more temperate. Second, the soil in Chile is not well-suited for coffee cultivation. Coffee plants need rich, loamy soil, and Chile's soil is more sandy. Third, labor costs in Chile are high. Coffee production is a labor-intensive process, and the cost of labor in Chile is higher than in many other coffee-producing countries.

As a result of these factors, Chile is not a major coffee producer. It only produces a small amount of coffee, and it is not a significant player in the global coffee market.

The correct answer is: A. Soda glass.

Soda glass is a type of glass that is made from silica, soda ash, and lime. It is the most common type of glass used in windows, bottles, and other containers. Soda glass has a low melting point, which makes it easy to work with. It is also relatively inexpensive to produce.

Soda glass can block ultraviolet rays because it contains iron oxide. Iron oxide absorbs ultraviolet light, which prevents it from passing through the glass. This makes soda glass a good choice for applications where it is important to protect people from exposure to ultraviolet light, such as in windows and sunglasses.

Pyrex glass is a type of borosilicate glass that is made from silica, boric oxide, and soda ash. It is a more heat-resistant type of glass than soda glass. Pyrex glass is often used in cookware and laboratory equipment.

Jena glass is a type of optical glass that is made from silica, soda ash, and lime. It is a high-quality type of glass that is used in lenses, prisms, and other optical instruments.

Crooked glass is a type of glass that is not flat. It is often used in decorative applications, such as stained glass windows.

In conclusion, the correct answer is: A. Soda glass.

The correct answer is C. The moon's gravity is about 1/6th of the Earth's gravity. This means that if you weigh 100 pounds on Earth, you would weigh about 16.6 pounds on the moon. The moon's gravity is weaker because it is smaller than the Earth. The force of gravity is proportional to the mass of the object and inversely proportional to the square of the distance between the objects. The moon is much smaller than the Earth, so its mass is much less. The distance between the Earth and the moon is also much greater than the distance between the Earth and any point on its surface. This means that the force of gravity from the moon is much weaker than the force of gravity from the Earth.

Option A is incorrect because the moon's gravity is not 1/4th of the Earth's gravity. Option B is incorrect because the moon's gravity is not 1/5th of the Earth's gravity. Option D is incorrect because the moon's gravity is not 1/8th of the Earth's gravity.

Option D, domestic lighting, is incorrect because carbon arc lamps are not commonly used in domestic lighting. Modern domestic lighting uses incandescent bulbs, halogen bulbs, or LEDs. These light sources are more efficient and produce less heat than carbon arc lamps.

The correct answer is: A. zones of climate.

The latitudinal differences in pressure delineate a number of major pressure zones, which correspond with zones of climate. These zones are:

• The equatorial low-pressure zone, which is located near the equator and is characterized by warm, moist air.
• The subtropical high-pressure zones, which are located at about 30 degrees north and south latitude and are characterized by dry, sinking air.
• The mid-latitude low-pressure zones, which are located at about 60 degrees north and south latitude and are characterized by stormy weather.
• The polar high-pressure zones, which are located at the poles and are characterized by cold, dry air.

The Earth's climate is determined by a number of factors, including the amount of solar radiation that it receives, the distribution of land and water, and the presence of oceans and mountains. The latitudinal differences in pressure are one of the most important factors that influence the Earth's climate. The equatorial low-pressure zone is the warmest part of the Earth because it receives the most direct sunlight. The subtropical high-pressure zones are the driest parts of the Earth because the sinking air prevents clouds from forming. The mid-latitude low-pressure zones are the stormiest parts of the Earth because the rising air causes clouds to form and thunderstorms to develop. The polar high-pressure zones are the coldest parts of the Earth because they receive the least direct sunlight.

The latitudinal differences in pressure also influence the Earth's weather patterns. The trade winds, which are the prevailing winds that blow from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere, are caused by the difference in pressure between the equatorial low-pressure zone and the subtropical high-pressure zones. The jet streams, which are fast-flowing bands of air that are located in the upper atmosphere, are caused by the difference in temperature between the polar high-pressure zones and the mid-latitude low-pressure zones.

The correct answer is B. Thyroxin.

Thyroxin is a thyroid hormone that regulates carbohydrate metabolism. It is produced by the thyroid gland and is essential for normal growth and development. Thyroxin helps to regulate the body's metabolism by increasing the rate at which cells use oxygen and glucose. This helps to increase the production of energy and the breakdown of carbohydrates. Thyroxin also helps to regulate the body's temperature and heart rate.

Parathyroid hormone is a hormone that regulates calcium and phosphorus levels in the blood. It is produced by the parathyroid glands, which are four small glands located in the neck. Parathyroid hormone helps to maintain a healthy balance of calcium and phosphorus in the blood by increasing the absorption of calcium from the intestines and the release of calcium from the bones. Parathyroid hormone also helps to increase the excretion of phosphorus in the urine.

Estrogen is a hormone that is produced by the ovaries. It is responsible for the development of female secondary sexual characteristics, such as the growth of breasts and the development of a feminine body shape. Estrogen also plays a role in the regulation of the menstrual cycle and in the maintenance of pregnancy.

Parathyroid hormone and estrogen do not regulate carbohydrate metabolism.

The correct answer is at.

The correct answer is (a) 8 years.

Under the Hindu Adoption and Maintenance Act, 1956, a child to be adopted should not have, in the absence of a valid custom, completed the age of 8 years. This means that the child must be under the age of 8 at the time of the adoption.

There are a few exceptions to this rule. For example, if the child is a Hindu by religion and has been abandoned by his or her parents, he or she may be adopted even if he or she is over the age of 8. Additionally, if the child is a Hindu by religion and has been orphaned, he or she may be adopted even if he or she is over the age of 8.

The purpose of this rule is to protect the rights of children. By limiting the age of adoption to 8 years, the law ensures that children are not adopted by people who may not have their best interests at heart. Additionally, the law helps to ensure that children are adopted into families that can provide them with the love and support they need.

The other options are incorrect because they are not the maximum age limit for adoption under the Hindu Adoption and Maintenance Act, 1956.

The correct answer is (a). Every transfer of immovable property made with intent to defeat or delay the creditors of the transferor shall be voidable at the option of such creditors.

This is because Section 53 of the Indian Contract Act, 1872 states that "Every transfer of immovable property made with intent to defeat or delay the creditors of the transferor shall be voidable at the option of such creditors."

This means that if a creditor can prove that a transfer of immovable property was made with the intent to defeat or delay them, they can have the transfer declared void. This can be done by filing a suit in court.

If the transfer is declared void, the property will be returned to the transferor's estate and the creditors will be able to recover their debts from the property.

Option (b) is incorrect because it states that the transfer is not void. This is not correct because Section 53 of the Indian Contract Act, 1872 states that the transfer is voidable.

Option (c) is incorrect because it states that the transfer is void. This is not correct because Section 53 of the Indian Contract Act, 1872 states that the transfer is voidable.

Option (d) is incorrect because it states that none of the above is correct. This is not correct because the correct answer is (a).

The correct answer is (d). Apples are a good source of potassium, which is an important mineral for heart health. Potassium helps to regulate blood pressure and heart rhythm. It also helps to prevent the build-up of plaque in the arteries.

Sodium and potassium are both electrolytes, which are minerals that help to regulate the body's fluid balance. However, too much sodium can raise blood pressure, while potassium can help to lower it. Phosphorus is a mineral that is important for bone health. Magnesium is a mineral that is important for muscle and nerve function.

Apples are also a good source of fiber, which can help to lower cholesterol levels. They are also a good source of antioxidants, which can help to protect the body against damage from free radicals.

Overall, apples are a healthy food that can be beneficial for heart health.

The correct answer is D. Abundant food production.

The other options are all major challenges to food security in West Bengal.

* Climate change and natural disasters can damage crops and infrastructure, making it difficult to produce and distribute food.
* Land fragmentation can make it difficult to farm efficiently and can lead to soil erosion.
* Low agricultural productivity can mean that there is not enough food to meet the needs of the population.

Abundant food production is not a major challenge to food security in West Bengal. In fact, West Bengal is a net exporter of food. However, the other challenges mentioned above can still make it difficult for people in West Bengal to access food.

The correct answer is: D. None of the above

If the prices increase by 100% over the previous year and GNP is constant, it means that we cannot determine whether production has increased, decreased, or stayed the same. This is because GNP is a measure of the total market value of all final goods and services produced in a country in a given year, while prices are a measure of the average level of prices of goods and services in a country in a given year. Therefore, if prices increase by 100%, it could mean that production has increased, but prices have also increased, so the total value of production may not have changed. Alternatively, it could mean that production has decreased, but prices have also decreased, so the total value of production may not have changed. Or, it could mean that production has stayed the same, but prices have increased.

To determine whether production has increased, decreased, or stayed the same, we would need to know more information, such as the quantity of goods and services produced.

The correct answer is: D. caused

The stratospheric ozone layer is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation. It contains high concentrations of ozone (O3) relative to other parts of the atmosphere, although still small in relation to other gases in the stratosphere. The ozone layer contains less than 10 parts per million of ozone, while the average ozone concentration in Earth's atmosphere as a whole is about 0.3 parts per million. The ozone layer is mainly found in the lower portion of the stratosphere, from approximately 20 to 30 kilometers (12 to 19 mi) above Earth, although its thickness varies seasonally and geographically.

The ozone layer is important because it protects life on Earth from harmful ultraviolet radiation. Ultraviolet radiation can cause skin cancer, cataracts, and other health problems. It can also damage plants and animals. The ozone layer is also important for the Earth's climate. It helps to regulate the Earth's temperature by absorbing ultraviolet radiation.

The ozone layer is being depleted by human activities, mainly the release of chlorofluorocarbons (CFCs) into the atmosphere. CFCs are chemicals that were once used in refrigerators, air conditioners, and other products. They are now banned in most countries, but they remain in the atmosphere for many years. CFCs break down in the stratosphere and release chlorine atoms. These chlorine atoms react with ozone molecules, destroying them.

The depletion of the ozone layer is a serious problem. It is causing an increase in the amount of ultraviolet radiation reaching the Earth's surface. This is increasing the risk of skin cancer, cataracts, and other health problems. It is also damaging plants and animals.

There are a number of things that can be done to protect the ozone layer. One is to reduce the use of CFCs and other ozone-depleting substances. Another is to use products that are ozone-friendly. We can also help to protect the ozone layer by reducing our energy consumption. This will help to reduce the amount of CFCs and other ozone-depleting substances that are released into the atmosphere.

The disruption of the ozone layer is obviously fraught with dangerous consequences. The ozone layer is essential for life on Earth, and its depletion is a serious threat to our health and well-being. We must take action to protect the ozone layer and ensure its continued protection for future generations.

The other options are not correct because they do not accurately describe the relationship between the disruption of the ozone layer and dangerous consequences. Option A, "involving," does not accurately describe the relationship because the disruption of the ozone layer is not simply a matter of involving dangerous consequences. Option B, "concerned," does not accurately describe the relationship because the disruption of the ozone layer is not simply a matter of being concerned about dangerous consequences. Option C, "followed," does not accurately describe the relationship because the disruption of the ozone layer does not simply follow dangerous consequences.

The correct answer is B. Diatomic.

It occurs naturally in elemental form as the mineral sulfur, or as an impurity in other minerals, such as pyrite and cinnabar. Elemental sulfur is a bright yellow, crystalline solid at standard temperature and pressure. It is odorless and has a slightly bitter taste. Sulfur is a non-metal and is not very reactive. It is insoluble in water, but soluble in carbon disulfide. Sulfur is an important element in many compounds, including sulfuric acid, sulfur dioxide, and sulfurous acid. It is also used in the production of gunpowder, matches, and fireworks.

The atomicity of an element is the number of atoms that make up a molecule of that element. The atomicity of sulfur is 2, which means that a molecule of sulfur contains 2 atoms of sulfur. Sulfur is a diatomic element because it forms molecules with two atoms of sulfur. The two atoms of sulfur are held together by covalent bonds. Covalent bonds are strong bonds that form when atoms share electrons.

The other options are incorrect because they do not represent the atomicity of sulfur. Option A, polyatomic, is incorrect because sulfur is not a polyatomic element. A polyatomic element is an element that forms molecules with more than two atoms. Option C, monoatomic, is incorrect because sulfur is not a monoatomic element. A monoatomic element is an element that forms molecules with only one atom. Option D, triatomic, is incorrect because sulfur is not a triatomic element. A triatomic element is an element that forms molecules with three atoms.

The answer is C. Kidnap.

The other four words (A. Assassinate, B. Kill, D. Stab, and E. Murder) all refer to the act of intentionally taking a human life. Kidnapping, on the other hand, is the act of taking someone away against their will, without their consent. It is a crime that can be committed for a variety of reasons, such as ransom, sexual assault, or forced labor.

Assassination is the act of killing a person, especially a public figure, for political or religious reasons. Murder is the unlawful killing of another human being with malice aforethought. Stab is a verb meaning to pierce or wound with a sharp object, such as a knife.

The correct answer is: C. Third World Nations.

The G-15 is a group of developing countries that was founded in 1989. The group's goal is to promote economic cooperation and development among its members. The G-15 currently consists of 15 countries: Algeria, Argentina, Brazil, Chile, Egypt, India, Indonesia, Iran, Jamaica, Kenya, Malaysia, Mexico, Nigeria, Peru, and Venezuela.

The term "Third World" was first used during the Cold War to refer to countries that were not aligned with either the United States or the Soviet Union. The term is now often used to refer to developing countries.

The G-15 has been criticized for its lack of effectiveness. Some critics argue that the group is too large and diverse to be able to achieve its goals. Others argue that the group is too focused on economic issues and does not do enough to address social and political issues.

Despite these criticisms, the G-15 remains an important forum for developing countries to discuss their common concerns and to work together to promote their economic development.

The other options are incorrect because:

• A. First World Nations refers to the countries that were aligned with the United States during the Cold War.
• B. Second World Nations refers to the countries that were aligned with the Soviet Union during the Cold War.
• D. Fourth World Nations is a term that is sometimes used to refer to the poorest countries in the world.

Cauliflower is the correct answer. It is a cool-weather crop that is best grown in the spring or fall. It can be grown in the winter in some areas, but it is more susceptible to disease and pests in the cold weather. Okra, brinjal, and cucumber are all warm-weather crops that are best grown in the summer.

Cauliflower is a member of the Brassica family, which also includes broccoli, Brussels sprouts, and kale. It is a nutrient-rich vegetable that is low in calories and high in fiber. Cauliflower is a good source of vitamins C and K, as well as folate and potassium. It also contains compounds that have been shown to have anticancer properties.

Cauliflower can be eaten raw or cooked. It is a versatile vegetable that can be used in a variety of dishes, such as soups, stews, casseroles, and stir-fries. It can also be roasted, grilled, or steamed.

To grow cauliflower, you will need to start with seeds or seedlings. The seeds should be planted in the spring or fall, about six weeks before the last frost. The seedlings should be planted about two weeks before the last frost.

Cauliflower plants need full sun and well-drained soil. They should be watered regularly, especially during dry weather. The plants should be fertilized every two weeks with a balanced fertilizer.

Cauliflower is ready to harvest when the heads are firm and white. The heads should be cut off with a sharp knife. The leaves can be left on the head or removed.

Cauliflower can be stored in the refrigerator for up to two weeks. It can also be frozen for up to six months.

The correct answer is: A. six banks.

In April 1980, the government of India nationalized six banks:

• The Bank of India
• The Central Bank of India
• The Punjab National Bank
• The Canara Bank
• The Indian Bank
• The United Commercial Bank

The nationalization of these banks was part of a larger effort by the government to increase its control over the Indian economy. The government believed that by nationalizing these banks, it would be able to better regulate the financial system and promote economic development.

The nationalization of these banks was controversial at the time, and it remains a controversial topic today. Some people argue that the nationalization of these banks was necessary to protect the interests of depositors and to promote economic development. Others argue that the nationalization of these banks was a mistake that led to inefficiency and corruption.

Regardless of the merits of the nationalization of these banks, it is a significant event in Indian history. It is a reminder of the government's role in the economy and of the power of the state to intervene in the private sector.

The correct answer is A. Absorption of corresponding wavelengths by the outer layers of the sun.

The dark lines in the solar spectrum are called Fraunhofer lines, and they are caused by the absorption of certain wavelengths of light by the gases in the sun's atmosphere. The different elements in the sun's atmosphere absorb different wavelengths of light, so the Fraunhofer lines are a unique fingerprint of the sun's composition.

Option B is incorrect because destructive interference is not a factor in the formation of Fraunhofer lines. Option C is incorrect because the prism used in the photograph does not absorb any wavelengths of light. Option D is incorrect because the light emitted by the core of the sun does contain all wavelengths of light, but the outer layers of the sun absorb some of these wavelengths.

The correct answer is: D. for six years or till the age of 65 years, whichever is earlier.

The Chief Election Commissioner of India is appointed by the President of India. The term of office of the Chief Election Commissioner is six years or till the age of 65 years, whichever is earlier. The Chief Election Commissioner can be removed from office only on the recommendation of a high powered committee consisting of the Prime Minister, the Leader of the Opposition in the Lok Sabha and the Chief Justice of India.

Option A is incorrect because the Chief Election Commissioner does not hold office for a period of six years. The term of office of the Chief Election Commissioner is six years or till the age of 65 years, whichever is earlier.

Option B is incorrect because the Chief Election Commissioner does not hold office during the pleasure of the President. The Chief Election Commissioner can be removed from office only on the recommendation of a high powered committee consisting of the Prime Minister, the Leader of the Opposition in the Lok Sabha and the Chief Justice of India.

Option C is incorrect because the Chief Election Commissioner does not hold office for five years or till the age of 60 years, whichever is earlier. The term of office of the Chief Election Commissioner is six years or till the age of 65 years, whichever is earlier.

The correct answer is: C. concerted

A concerted effort is a joint action taken by a group of people or organizations towards a common goal. In this case, the principal and staff have made concerted efforts to enable the students to attend college on the days of the bus strike. This includes providing alternative transportation options, such as shuttle buses or carpooling, and offering flexible scheduling options, such as allowing students to make up missed work.

The other options are not as accurate. Option A, integrated, means combining or coordinating different parts into a whole. This does not accurately describe the efforts of the principal and staff, which are focused on a single goal. Option B, deliberate, means done with careful thought and planning. This is also not an accurate description, as the efforts of the principal and staff are not necessarily based on careful thought and planning. Option D, systematic, means done according to a plan or system. This is also not an accurate description, as the efforts of the principal and staff are not necessarily based on a plan or system.

The correct answer is C. Helium.

An alpha particle is a positively charged particle that is emitted from the nucleus of an atom during radioactive decay. It is composed of two protons and two neutrons, and has a mass of 4 atomic mass units (AMU). The nucleus of a helium atom is also composed of two protons and two neutrons, so an alpha particle is essentially the same as a helium nucleus.

The other options are incorrect because they are not composed of two protons and two neutrons. Lithium has three protons and four neutrons, hydrogen has one proton and no neutrons, oxygen has eight protons and eight neutrons.

The correct answer is: Nicolo Conti.

Nicolo Conti was an Italian merchant and traveler who visited India during the Vijayanagara period. He was the first European to write about the Vijayanagara Empire, and his accounts provide valuable insights into the history and culture of the empire.

Megasthenes was a Greek ambassador who visited India during the Mauryan period. He is best known for his book Indica, which provides a detailed account of Indian society and culture.

Fa-Hien was a Chinese Buddhist monk who visited India during the Gupta period. He is best known for his book Faxian's Travels, which provides a detailed account of his travels through India.

All of these travelers provided valuable insights into India, but only Nicolo Conti visited India during the Vijayanagara period.

The correct answer is (c) Kanpur.

Kanpur is a city in the state of Uttar Pradesh, India. It is the 12th most populous city in India and the 10th most populous city in the world. Kanpur is a major industrial city and is known for its leather industry. The city is also home to a number of educational institutions, including the Indian Institute of Technology Kanpur.

Kanpur has been ranked as one of the most polluted cities in the world. The city's air quality is poor due to a number of factors, including industrial emissions, vehicular emissions, and dust. The city's air quality has been a major concern for the residents of Kanpur and the government has taken a number of measures to improve the air quality of the city.

The following are the reasons for Kanpur having the highest air pollution in 2019:

• Industrial emissions: Kanpur is a major industrial city and is home to a number of industries, including the leather industry. These industries emit a large amount of pollutants into the air, which contributes to the city's poor air quality.
• Vehicular emissions: Kanpur is a major transportation hub and has a large number of vehicles. These vehicles emit a large amount of pollutants into the air, which contributes to the city's poor air quality.
• Dust: Kanpur is located in a dusty region and the city is often covered in dust. This dust can also contribute to the city's poor air quality.

The government has taken a number of measures to improve the air quality of Kanpur, including:

• Implementing emission control measures for industries
• Promoting the use of public transport
• Planting trees
• Raising awareness about air pollution

However, these measures have not been effective in improving the air quality of Kanpur. The city's air quality is still poor and the residents of Kanpur are facing a number of health problems due to air pollution.

The correct answer is (a) 2005.

The National Rural Employment Guarantee Act (NREGA) is a social security program in India that guarantees employment to rural households who volunteer to do unskilled manual work. It was launched in 2005 by the United Progressive Alliance (UPA) government.

The act provides for 100 days of guaranteed employment in a financial year to every household whose adult members volunteer to do unskilled manual work. The wages are paid at the minimum wage rate fixed by the government.

The act has been successful in providing employment to millions of rural people and has helped to reduce poverty and improve the quality of life in rural areas.

Option (b), 2000, is incorrect because the NREGA was launched in 2005.

Option (c), 1996, is incorrect because the NREGA was launched in 2005.

Option (d), 1992, is incorrect because the NREGA was launched in 2005.

The correct answer is (a) Sugar.

The sugar sector has seen a high rate of growth in its cooperative units in recent years. This is due to a number of factors, including the government's focus on promoting cooperatives, the increasing demand for sugar, and the relatively low cost of production in the sugar sector.

Cooperatives are owned and run by their members, and they are often more efficient than traditional businesses. This is because they are able to pool resources and share costs. Cooperatives are also more responsive to the needs of their members, and they are often more willing to take risks.

The demand for sugar is increasing due to the growing population and the increasing popularity of sweet foods. The cost of production in the sugar sector is relatively low, which makes it an attractive investment for cooperatives.

The government has been promoting cooperatives in recent years, and this has helped to boost the growth of the sugar sector. The government has provided financial assistance to cooperatives, and it has also provided training and support.

The sugar sector is a major contributor to the Indian economy. It employs millions of people, and it generates billions of dollars in revenue each year. The growth of the sugar sector is good news for the Indian economy, and it is also good news for the millions of people who depend on the sugar sector for their livelihoods.

The other options are not correct because they have not seen the same level of growth as the sugar sector. The cotton textile sector has been struggling in recent years due to the competition from China. The jute sector has also been struggling due to the competition from other countries, such as Bangladesh. The cement sector has seen some growth, but it has not been as high as the growth in the sugar sector.

Per capita availibility of milk in West Bengal is 161 grams per day which is lower than the national availibility of 337 grams per day per person.

The correct answer is D. RSPQ.

The correct sequence of the sentences is:

D. RSPQ

1. There was presumably, some defect in the reversal handle of the tram and its main switch had not been put off.
2. As a result, when the power supply was restored in the early morning the tram began to move.
3. In the early morning of 19 January it suddenly started backing out of the depot on its own.
4. Tramways sources explained that power supply to the overhead wires at the siding had been switched off for some repair work.
5. It went up a quarter mile away, crashed into state bus which caught fire went it smashed into an electric feeder box and a water tap.

The first sentence introduces the main idea of the paragraph, which is that a tram went on a trip all by itself and ended up in a disaster. The second sentence explains how the tram was able to move, even though the power supply had been switched off. The third sentence provides more details about the tram's journey, including the fact that it crashed into a bus. The fourth sentence provides more information about the power outage, and the fifth sentence describes the aftermath of the crash.

The other options are incorrect because they do not follow the logical order of events. For example, option A (PQRS) puts the sentence about the power outage before the sentence about the tram's journey. This is not possible, because the tram could not have moved if the power supply had not been restored. Option B (PRQS) puts the sentence about the tram's journey before the sentence about the power outage. This is also not possible, because the tram could not have crashed into the bus if it had not been moving. Option C (RQSP) puts the sentence about the tram's journey before the sentence about the defect in the reversal handle. This is not possible, because the defect in the reversal handle was the reason why the tram was able to move.

The correct answer is B. Geneva.

The World Trade Organization (WTO) is an intergovernmental organization that regulates international trade. It was established on 1 January 1995 as the successor to the General Agreement on Tariffs and Trade (GATT). The WTO's headquarters is located in Geneva, Switzerland.

The WTO's mission is to help trade flow smoothly, freely, fairly and predictably. It does this by providing a forum for trade negotiations, by setting rules for trade between its members, and by providing a system for settling trade disputes.

The WTO's membership has grown from 123 countries in 1995 to 164 countries in 2023. The WTO's rules apply to all of its members, regardless of their size or economic development.

The WTO is a powerful organization that has a significant impact on the global economy. Its decisions can affect the prices of goods and services, the level of employment, and the competitiveness of businesses.

The WTO has been criticized for being too bureaucratic and for not doing enough to promote the interests of developing countries. However, it remains an important institution for the global trading system.

The other options are incorrect.

A. New York is the headquarters of the United Nations.
C. Madrid is the capital of Spain.
D. Paris is the capital of France.

The correct answer is A) 1.6.

The total fertility rate (TFR) is the average number of children that would be born to a woman over her lifetime if she were to experience the exact current age-specific fertility rates throughout her life. It is a more direct measure of the level of fertility than the crude birth rate, which is the number of births per 1,000 population in a given year.

The TFR in West Bengal as per the 2011 Census is 1.6. This means that, on average, a woman in West Bengal would have 1.6 children in her lifetime. This is below the replacement level of 2.1 children per woman, which is necessary to maintain a stable population. The low TFR in West Bengal is due to a number of factors, including increasing female education and employment, access to family planning services, and changing social norms about family size.

Option B, 1.8, is incorrect because the TFR in West Bengal is actually lower than this. Option C, 2.0, is incorrect because the TFR in West Bengal is actually lower than this. Option D, 2.2, is incorrect because the TFR in West Bengal is actually lower than this.

The correct answer is (a) Geneva.

The International Commission of Jurists (ICJ) is an independent non-governmental organization that promotes the rule of law and human rights. It was founded in Geneva, Switzerland, in 1952. The ICJ has a membership of over 60,000 lawyers and judges from over 100 countries. The ICJ's headquarters is located in Geneva, Switzerland.

The ICJ works to promote the rule of law and human rights through a variety of activities, including:

• Research and analysis of legal issues
• Advocacy and lobbying for legal reform
• Capacity building for lawyers and judges
• Education and outreach on legal issues

The ICJ is a leading voice for the rule of law and human rights. It has played a significant role in promoting these values around the world.

The other options are incorrect because the ICJ's headquarters is not located in those cities.

(b) Rome is the capital of Italy and the seat of the Catholic Church.

(c) Paris is the capital of France and a major center of culture, fashion, and tourism.

(d) London is the capital of the United Kingdom and a major financial center.

The correct answer is B. democracy.

A totalitarian regime is a form of government in which the state holds total authority over the society and seeks to control all aspects of public and private life. This is often achieved through the use of violence, censorship, and propaganda.

Democracy, on the other hand, is a form of government in which the people hold power. This is typically achieved through a system of elected representatives who make decisions on behalf of the people.

The overthrow of a totalitarian regime by the people is truly the triumph of democracy because it represents the people taking back control of their own lives. It is a victory for freedom and human rights.

Imperialism is a policy of extending a country's power and influence through colonization, use of military force, or other means. Dictatorship is a form of government in which one person or a small group holds absolute power. Communism is a political and economic system that seeks to create a classless society in which the major means of production, such as mines and factories, are owned and controlled by the public.

While imperialism, dictatorship, and communism may all be forms of government that are opposed to democracy, they are not the same as democracy. Democracy is a specific form of government that is based on the principle of popular sovereignty, or the idea that the people are the source of all political power.

The correct answer is: A) Sikhs.

Baisakhi is a major Sikh festival celebrated on the first day of the month of Vaisakh (the second month of the Nanakshahi calendar, which is based on the solar cycle), which usually falls in April. It marks the beginning of the harvest season and the Sikh New Year. The day also commemorates the establishment of the Khalsa Panth, the collective body of the Sikh people, by Guru Gobind Singh on 1699.

Hindus also celebrate Baisakhi, but it is not as important to them as it is to Sikhs. For Hindus, Baisakhi is a harvest festival and a time to celebrate the arrival of spring. It is also a time to pay tribute to the sun god, Surya.

Muslims and Christians do not celebrate Baisakhi.

The correct answer is A) Communist Party of India (Marxist).

The Left Front government was a coalition of communist and left-wing political parties in West Bengal, India. It was formed in 1977 and ruled the state for 34 years, until 2011. The Left Front was led by the Communist Party of India (Marxist), which was the largest party in the coalition. The other major parties in the Left Front were the Communist Party of India, the Revolutionary Socialist Party, and the Forward Bloc.

The Left Front government was known for its pro-poor policies and its focus on education and healthcare. It also implemented land reforms and promoted industrialization. However, the Left Front was also criticized for its authoritarian style of governance and its failure to address corruption.

In 2011, the Left Front was defeated by the Trinamool Congress in the West Bengal state elections. The Trinamool Congress is a regional political party that is led by Mamata Banerjee. The Trinamool Congress has a more populist and pro-business agenda than the Left Front.

The Left Front's defeat in 2011 was a major setback for the communist movement in India. It also marked the end of an era in West Bengal, where the Left Front had been in power for nearly three decades.

The correct answer is (b), Sonara-64.

Sonara-64 is a high-yielding semi-dwarf wheat variety that was developed in India in the 1960s. It was the first wheat variety to be developed through induced mutation, a process in which a plant's genetic material is altered using radiation or chemicals. Sonara-64 was a major breakthrough in the Green Revolution, which helped to increase agricultural production in India and other developing countries.

Kalyan Sona is another high-yielding wheat variety that was developed in India in the 1960s. However, it was not developed through induced mutation. Sharbati Sonara is a hybrid wheat variety that was developed in India in the 1980s. It is a cross between Sonara-64 and another wheat variety called Sharbati Sonora. Sonalika is a high-yielding wheat variety that was developed in India in the 1990s. It is not a hybrid variety.

Induced mutation is a process in which a plant's genetic material is altered using radiation or chemicals. This can be done to create new varieties of plants with desirable traits, such as resistance to pests or diseases. Induced mutation is a powerful tool that has been used to develop many important crops, including wheat.

The Green Revolution was a period of agricultural development that began in the 1940s and 1950s. It was a time of rapid technological and scientific advancement in agriculture, which led to increased crop yields and improved food security. The Green Revolution was a major success, and it helped to lift millions of people out of poverty.

The correct answer is C. 7.35-7.45.

The pH scale is a logarithmic scale that measures the acidity or alkalinity of a solution. A pH of 7 is considered neutral, a pH below 7 is acidic, and a pH above 7 is alkaline. The pH of human blood is slightly alkaline, with a normal range of 7.35-7.45. This pH is important for maintaining the proper function of cells and tissues. If the pH of blood falls outside of this range, it can lead to serious health problems, such as acidosis or alkalosis.

Option A is incorrect because it is too acidic. A pH of 7.1-7.15 is considered acidic, and can lead to health problems such as acidosis.

Option B is incorrect because it is too alkaline. A pH of 7.45-7.55 is considered alkaline, and can lead to health problems such as alkalosis.

Option D is incorrect because it is too narrow. The normal range of pH for human blood is 7.35-7.45, so option D does not include the entire range.

The correct answer is: A. Right to Equality.

• Article 15: Prohibition of discrimination on grounds of religion, race, caste, sex or place of birth.
• Article 16: Equality of opportunity in matters of public employment.
• Article 17: Abolition of untouchability.
• Article 18: Abolition of titles.

Article 14 of the Indian Constitution states that "The State shall not deny to any person equality before the law or the equal protection of the laws within the territory of India." This means that all persons are equal before the law and are entitled to equal protection of the law. The State cannot discriminate against any person on the grounds of religion, race, caste, sex, place of birth or any other ground.

Article 15 of the Indian Constitution states that "The State shall not discriminate against any citizen on grounds of religion, race, caste, sex, place of birth or any of them." This means that the State cannot discriminate against any citizen in any matter, such as employment, education, housing, etc., on the grounds of religion, race, caste, sex, place of birth or any other ground.

Article 16 of the Indian Constitution states that "There shall be equality of opportunity for all citizens in matters relating to employment or appointment to any office under the State." This means that all citizens are entitled to equal opportunity in matters of employment or appointment to any office under the State. The State cannot discriminate against any citizen in matters of employment or appointment to any office on the grounds of religion, race, caste, sex, place of birth or any other ground.

Article 17 of the Indian Constitution states that "Untouchability is abolished and its practice in any form is forbidden. The enforcement of any disability arising out of untouchability shall be an offence punishable in accordance with law." This means that the practice of untouchability is abolished and its practice in any form is forbidden. The State cannot enforce any disability arising out of untouchability.

Article 18 of the Indian Constitution states that "No title shall be conferred by the State except for military and academic distinctions." This means that the State cannot confer any title on any person except for military and academic distinctions.

The Right to Equality is a fundamental right that is guaranteed to all citizens of India. It is a very important right that ensures that all citizens are treated equally before the law. The Right to Equality is a cornerstone of the Indian Constitution and it is one of the most important rights that Indian citizens enjoy.

The correct answer is: A) Financial assistance to widows.

The Anandadhara scheme is a social security scheme for widows in Andhra Pradesh, India. It provides financial assistance to widows who are below the poverty line. The scheme was launched in 2013 and is funded by the state government.

The scheme provides a monthly pension of Rs. 1,000 to eligible widows. The pension is payable for life. To be eligible for the scheme, a widow must be a resident of Andhra Pradesh and below the poverty line. She must also be a widow of a government employee or a farmer.

The Anandadhara scheme is a valuable social security scheme that provides financial assistance to widows in Andhra Pradesh. The scheme helps to improve the lives of widows and their families.

Option B, Old age pension, is not the correct answer because the Anandadhara scheme is specifically for widows. Old age pension schemes are available to all senior citizens, regardless of their marital status.

Option C, Maternity benefits, is not the correct answer because the Anandadhara scheme is not a maternity benefits scheme. Maternity benefits schemes provide financial assistance to women who have recently given birth.

Option D, Child care support, is not the correct answer because the Anandadhara scheme is not a child care support scheme. Child care support schemes provide financial assistance to families with young children.

The correct answer is: B. Fertilization of ova takes place in test tube which development of embryo occur in uterus.

In vitro fertilization (IVF) is a process in which an egg is fertilized by sperm outside the body. The fertilized egg, or embryo, is then placed in the woman's uterus, where it can implant and grow.

IVF is used when a woman has difficulty getting pregnant or carrying a pregnancy to term. It can also be used to help women who have a genetic disorder that could be passed on to their children.

The first successful IVF baby was born in 1978. Since then, millions of babies have been born using IVF.

Here is a brief explanation of each option:

• Option A: Fertilization of ova and development takes place in test tube. This is not correct. Fertilization takes place in a test tube, but development takes place in the woman's uterus.
• Option B: Fertilization of ova takes place in test tube which development of embryo occur in uterus. This is the correct answer.
• Option C: Fertilization takes place in uterus while development takes place in test tube. This is not correct. Fertilization takes place in a test tube, but development takes place in the woman's uterus.
• Option D: Development of ova take place in test tube without fertilization. This is not correct. Fertilization must take place before development can occur.

The correct answer is C. A ruby rod.

A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The first working laser was built in 1960 by Theodore Maiman at Hughes Research Laboratories. The active medium in Maiman's laser was a ruby rod.

A ruby rod is a cylindrical rod of synthetic ruby, a mineral composed of aluminum oxide with trace chromium impurities. The chromium impurities give ruby its red color. When a ruby rod is placed in a high-energy environment, such as a flash lamp, the chromium atoms are excited to a higher energy state. When these excited atoms decay back to their ground state, they emit light of a specific wavelength. This light is amplified by the other chromium atoms in the rod, and is emitted as a laser beam.

The other options are incorrect. A diamond block is not a suitable material for a laser because it does not have the necessary optical properties. Helium-neon gas and carbon dioxide gas are both used in lasers, but they were not the active medium in the first working laser.

The correct answer is (a).

The Lahore session of the Indian National Congress was held in December 1929. At this session, the Congress declared 'Poorna Swaraj' or complete independence as its goal.

The correct answer is: A) Eliminate hunger and malnutrition.

The "Food For All" campaign was launched in West Bengal in 2001 by the then Chief Minister, Jyoti Basu. The campaign aimed to eliminate hunger and malnutrition in the state. It was a multi-pronged approach that included increasing food production, improving access to food, and promoting nutrition education.

The campaign was successful in reducing the number of people living in hunger in West Bengal. According to the National Family Health Survey (NFHS), the proportion of people who were undernourished in the state declined from 23.5% in 1992-93 to 11.5% in 2005-06.

The "Food For All" campaign was an important step in improving the lives of people in West Bengal. It helped to ensure that everyone had access to enough food to eat and that they were getting the nutrients they needed to be healthy.

Here is a brief explanation of each option:

* Option A: Eliminate hunger and malnutrition. This is the correct answer. The "Food For All" campaign was launched to eliminate hunger and malnutrition in West Bengal.
* Option B: Promote food processing industries. This is not the correct answer. The "Food For All" campaign was not launched to promote food processing industries.
* Option C: Increase food exports. This is not the correct answer. The "Food For All" campaign was not launched to increase food exports.
* Option D: Encourage organic farming. This is not the correct answer. The "Food For All" campaign was not launched to encourage organic farming.

The correct answer is B. Melting point.

A fuse wire is a safety device that is used to protect electrical appliances from damage caused by an overload of current. The fuse wire is made of a metal with a low melting point, so that it will melt and break the circuit if the current becomes too high. This prevents the appliance from overheating and catching fire.

The other options are incorrect because:

• Resistance: A metal with a low resistance would allow more current to flow, which would increase the risk of an overload.
• Specific gravity: The specific gravity of a metal is its density relative to water. This has no effect on its melting point.
• Conductance: The conductance of a metal is its ability to conduct electricity. This has no effect on its melting point.

The correct answer is (d). A Sikh is not a Hindu within the meaning of Section 2 of the Hindu Marriage Act, 1955.

The Hindu Marriage Act, 1955, is an Act to amend and codify the law relating to marriage among Hindus. The Act defines a Hindu as "a person who professes the Hindu religion and includes a person who is a Buddhist, Jain or Sikh by religion."

A Sikh is a follower of Sikhism, a monotheistic religion founded in the 15th century by Guru Nanak Dev Ji. Sikhs believe in one God, and they follow the teachings of the Guru Granth Sahib, the holy book of Sikhism.

Sikhs are not Hindus because they have a different religion, different beliefs, and different practices. Sikhs do not believe in the Hindu gods or goddesses, and they do not follow the Hindu scriptures. Sikhs also have a different way of life than Hindus. For example, Sikhs do not practice the Hindu caste system, and they do not believe in the Hindu concept of reincarnation.

The Hindu Marriage Act, 1955, is a law that applies to Hindus. Sikhs are not Hindus, so the Act does not apply to them.

The correct answer is: C. 11,000

Price elasticity of demand is a measure of how responsive consumers are to changes in price. A price elasticity of demand of -1.5 indicates that a 1% decrease in price will lead to a 1.5% increase in demand.

In this case, the business is planning to reduce the price of its product from Rs. 1 to Rs. 0.90. This is a 10% decrease in price. Assuming that the price elasticity of demand remains constant, we can expect demand to increase by 15%. This means that the business can now expect to sell 11,000 units of its product per month, up from 10,000 units per month before the price reduction.

Here is a brief explanation of each option:

• Option A: 8,500. This is the number of units that the business would expect to sell if the price elasticity of demand were -2. A price elasticity of demand of -2 indicates that a 1% decrease in price will lead to a 2% increase in demand. In this case, the business would expect to sell 8,500 units of its product per month, down from 10,000 units per month before the price reduction.
• Option B: 10,500. This is the number of units that the business would expect to sell if the price elasticity of demand were -1. A price elasticity of demand of -1 indicates that a 1% decrease in price will lead to a 1% increase in demand. In this case, the business would expect to sell 10,500 units of its product per month, up from 10,000 units per month before the price reduction.
• Option C: 11,000. This is the correct answer. As explained above, the business can now expect to sell 11,000 units of its product per month, up from 10,000 units per month before the price reduction.
• Option D: 11,500. This is the number of units that the business would expect to sell if the price elasticity of demand were -0.5. A price elasticity of demand of -0.5 indicates that a 1% decrease in price will lead to a 0.5% increase in demand. In this case, the business would expect to sell 11,500 units of its product per month, up from 10,000 units per month before the price reduction.

The correct answer is (a) Almora.

Almora is a district in the Kumaon region of Uttarakhand, India. It is the northernmost district of the state, bordering the state of Himachal Pradesh to the north and the state of Uttar Pradesh to the east. The district has a population of over 1.2 million people, of which over 80% live in rural areas.

The poverty ratio in Almora district is 31.7%, which is higher than the state average of 19.9%. The main reasons for poverty in Almora district are low levels of education, lack of employment opportunities, and poor infrastructure.

The government of Uttarakhand has implemented a number of schemes to reduce poverty in Almora district. These schemes include the Pradhan Mantri Jan Dhan Yojana (PMJDY), the Pradhan Mantri Kaushal Vikas Yojana (PMKVY), and the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA).

The PMJDY is a financial inclusion scheme that aims to provide financial services to the poor and vulnerable sections of society. The PMKVY is a skill development scheme that aims to provide training to the youth in order to make them employable. The MGNREGA is a rural employment guarantee scheme that aims to provide employment to the rural poor.

These schemes have helped to reduce poverty in Almora district, but there is still a long way to go. The government needs to continue to implement these schemes and also focus on improving the quality of education, providing employment opportunities, and improving infrastructure in order to reduce poverty in Almora district.

The other options are incorrect because they have a lower poverty ratio than Almora district. Champawat district has a poverty ratio of 28.8%, Chamoli district has a poverty ratio of 27.3%, and Tehri-Garhwal district has a poverty ratio of 26.2%.

The correct answer is: D. generous

A miser is a person who is extremely unwilling to spend money or give away possessions. A generous person is one who is willing to give or spend freely, especially on others.

The correct answer is A. Remain in the car.

If you are caught in a thunderstorm while driving, the safest place to be is in your car. The metal frame of the car will act as a Faraday cage, protecting you from the lightning strike. If you can, pull over to the side of the road and stop. If you cannot pull over, stay in the car and keep your hands off of the steering wheel and any metal objects.

Option B is incorrect because getting out of the car will put you at risk of being struck by lightning. Lightning is attracted to tall objects, and you will be the tallest object if you are standing outside of the car.

Option C is incorrect because taking shelter under a nearby tree will also put you at risk of being struck by lightning. Trees are tall objects that are easily attracted to lightning.

Option D is incorrect because touching an electric pole will also put you at risk of being struck by lightning. Electric poles are made of metal, which is a conductor of electricity. If you touch an electric pole during a thunderstorm, you will be a path for the lightning to travel to the ground.

The correct answer is: C. Nucleoid

The nucleoid is a region of a prokaryotic cell that contains all of the genetic material. It is not surrounded by a nuclear membrane, as is the nucleus of a eukaryotic cell. The nucleoid is typically a dense, irregularly shaped mass of DNA and associated proteins.

The nucleolus is a small, dense organelle found in the nucleus of eukaryotic cells. It is involved in the synthesis of ribosomes, which are the protein-synthesizing organelles of the cell.

The centrosome is a small, non-membranous organelle found in animal cells. It is involved in cell division, and contains the centrioles, which are the microtubule-organizing centers of the cell.

The nucleus is a large, membrane-bound organelle found in eukaryotic cells. It contains the cell's DNA, which is organized into chromosomes. The nucleus is also involved in the regulation of gene expression, and in the synthesis of proteins.

The correct answer is C. Review of constitutional validity of laws.

Judicial review is the power of the courts to declare laws unconstitutional. This power is not explicitly granted to the courts in the Constitution, but it has been inferred from the Supreme Court's power to decide cases that come before it.

The Supreme Court first exercised its power of judicial review in the case of Marbury v. Madison (1803). In that case, the Court declared that a law passed by Congress was unconstitutional. This decision established the principle that the Supreme Court has the power to strike down laws that it deems to be in violation of the Constitution.

Judicial review is an important power that helps to ensure that the government does not violate the rights of the people. It is also a power that can be abused, and it is important for the courts to exercise this power with caution.

Here is a brief explanation of each option:

• Option A: Review of its own verdict. This is not what judicial review means. Judicial review is the power of the courts to declare laws unconstitutional, not to review their own verdicts.
• Option B: Review of the functioning of judiciary in country. This is also not what judicial review means. Judicial review is the power of the courts to declare laws unconstitutional, not to review the functioning of the judiciary.
• Option C: Review of constitutional validity of laws. This is what judicial review means. Judicial review is the power of the courts to declare laws unconstitutional.
• Option D: Timely review of constitution. This is not what judicial review means. Judicial review is the power of the courts to declare laws unconstitutional, not to review the constitution.

The correct answer is A. Lactic acid.

Lactic acid is a byproduct of anaerobic respiration, which is a type of respiration that occurs when there is not enough oxygen available. When muscles are working hard, they need more oxygen than they can get from the blood. This causes them to switch to anaerobic respiration, which produces lactic acid as a waste product.

Lactic acid can build up in the muscles, causing them to become sore and cramped. This is why people often get cramps after strenuous exercise.

Ethanol is a type of alcohol that is found in alcoholic beverages. It is not produced by the body during anaerobic respiration.

Pyruvic acid is a chemical that is produced during glycolysis, which is the first step in cellular respiration. It is not a waste product, and it does not cause cramps.

Glucose is a type of sugar that is the body's main source of energy. It is not produced by the body during anaerobic respiration, and it does not cause cramps.

The correct answer is C. 1776.

Adam Smith's major work, An Inquiry into the Nature and Causes of the Wealth of Nations, was published in 1776. It is considered one of the most important books ever written on economics. In it, Smith argues that the wealth of a nation is not determined by the amount of gold and silver it possesses, but rather by the productivity of its people. He also argues that the free market is the best way to organize an economy, as it allows for the efficient allocation of resources and the division of labor.

The other options are incorrect. Option A, 1756, is the year that Smith's Theory of Moral Sentiments was published. Option B, 1766, is the year that Smith was appointed as a commissioner of customs in Scotland. Option D, 1786, is the year that Smith died.

The correct answer is C. Outstanding performance in sports.

The Arjuna Award is the second highest sporting honour of India, awarded by the Ministry of Youth Affairs and Sports to recognize "outstanding performance in National and International sports". It is named after Arjuna, the Pandava prince from the Mahabharata who was a skilled archer.

The award was instituted in 1961 and is given annually to sportspersons who have excelled in their respective fields. The award consists of a bronze statuette of Arjuna, a scroll of honour, and a cash prize.

Some of the notable recipients of the Arjuna Award include Sachin Tendulkar, P. V. Sindhu, and Milkha Singh.

Option A is incorrect because the Kirti Chakra is awarded for exceptional service in emergency.

Option B is incorrect because the Ashoka Chakra is awarded for bravery on battlefield.

Option D is incorrect because the Magsaysay Award is awarded for exceptional service in slum dwellers.

The correct answer is: C. Total internal reflection.

Fibre optics work on the principle of total internal reflection. This is the phenomenon that occurs when light passes from a medium with a higher refractive index to a medium with a lower refractive index, and the angle of incidence is greater than the critical angle. In this case, all of the light is reflected back into the first medium.

This principle is used in fibre optic cables to transmit light over long distances. The light is guided down the cable by the total internal reflection at the interface between the core and cladding of the fibre. The core is made of a material with a higher refractive index than the cladding, so the light is always reflected back into the core.

Scattering of light is the phenomenon that occurs when light is scattered in all directions by particles in a medium. This can happen when light passes through a medium with particles that are much smaller than the wavelength of light. The particles can be dust, water droplets, or even air molecules.

Total internal absorption is the phenomenon that occurs when light is absorbed by a material. This can happen when light passes through a material with a high absorption coefficient. The absorption coefficient is a measure of how much light is absorbed by the material per unit distance.

Optical rotation is the phenomenon that occurs when light is rotated as it passes through a material. This can happen when the material has a chiral structure. A chiral structure is a structure that is not identical to its mirror image.

The correct answer is (c).

F is the brother of A. C is the daughter of A. K is the sister of F. G is the brother of C.

An uncle is the brother of a parent. In this case, F is the brother of A, who is the parent of C. Therefore, F is the uncle of G.

A is the father of C, but not the uncle of G.

C is the daughter of A, but not the uncle of G.

K is the sister of F, but not the uncle of G.

The correct answer is D. Melanin.

Melanin is a pigment that gives color to skin, hair, and eyes. It is produced by cells called melanocytes. There are two types of melanin: eumelanin and pheomelanin. Eumelanin is responsible for dark hair and skin color, while pheomelanin is responsible for lighter hair and skin color. The amount of melanin produced by melanocytes is determined by genetics and environmental factors, such as sun exposure.

Luciferin is a chemical that is found in fireflies and other bioluminescent organisms. It is responsible for the production of light in these organisms. Haemoglobin is a protein that is found in red blood cells. It is responsible for carrying oxygen throughout the body. Flavonoids are a type of plant pigment that is responsible for the color of fruits and vegetables. They also have antioxidant properties.

Melanin is the most important pigment in human skin. It protects the skin from the sun's harmful ultraviolet rays. Melanin also helps to regulate body temperature. People with darker skin have more melanin than people with lighter skin. This is why people with darker skin are less likely to get sunburned or develop skin cancer.

The correct answer is (c) Twenty.

• Option E: Only either I or III is implicit. This is not the correct answer because assumption I is implicit.

The correct answer is (d).

A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers. A number that remains unchanged if its digits are reversed is called a palindromic number.

The only palindromic prime number between 10 and 40 is 111. However, the square of 111 is 12321, which is not a prime number.

Therefore, the square of a prime number between 10 and 40 that remains unchanged if its digits are reversed is not a prime number.

The correct answer is C. Dhokra Damar.

Dokra is a unique metal casting technique that is practiced by the Dhokra Damar community in West Bengal. It is a lost-wax casting technique that is used to create a variety of objects, including jewelry, sculptures, and utensils. The process of making a Dokra object begins with the creation of a wax model of the desired object. This model is then covered in a layer of clay, which is fired to harden. Once the clay is fired, the wax is melted out, leaving a hollow cavity in the clay. Molten metal is then poured into the cavity, and the clay is removed once the metal has cooled. The final product is a metal object that is in the shape of the original wax model.

The Dhokra Damar community has been practicing this technique for centuries, and it is a vital part of their culture. The objects that they create are not only beautiful, but they are also functional. Dokra objects are often used in religious ceremonies, and they are also prized by collectors.

The Dhokra Damar community is facing a number of challenges, including the loss of traditional knowledge and the competition from mass-produced goods. However, they are working to preserve their culture and their craft, and they are committed to passing it on to future generations.

The other options are incorrect because they do not refer to the community that practices Dokra craft.

• United Kingdom
• United States
• European Union

The G20 meets annually at the level of heads of state and government, and more frequently at the level of finance ministers and central bank governors. The G20 has been instrumental in coordinating international economic policy responses to the global financial crisis of 2008-2009, and in addressing other global challenges such as climate change, food security, and inequality.

Option B is incorrect because the G20 has 20 members, not 8.

Option C is incorrect because the G20 has 20 members, not 12.

Option D is incorrect because the G20 has 20 members, not 16.

The correct answer is: C. Forced vibrations

When a vibrating tuning fork is placed on a table, the table vibrates at the same frequency as the tuning fork. This is because the table is forced to vibrate by the tuning fork. The forced vibrations of the table cause the air molecules around the table to vibrate, which produces sound waves. The sound waves travel through the air and reach our ears, where they are converted into electrical signals that are sent to our brains. Our brains interpret these electrical signals as sound.

Reflection, refraction, and damped vibrations are not the correct answers because they do not explain why a loud sound is heard when a vibrating tuning fork is placed on a table.

Reflection is the bouncing of a wave off of a surface. Refraction is the bending of a wave as it passes from one medium to another. Damped vibrations are vibrations that gradually decrease in amplitude over time.

In the case of a vibrating tuning fork placed on a table, the sound is not caused by reflection, refraction, or damped vibrations. The sound is caused by forced vibrations.

The first Bengali talkie Jamai Shashthi (a short film) was released on 11th April, 1931 at Crown Cinema Hall in Kolkata.

The correct answer is B. went.

The sentence is in the past tense, so the verb must be in the past tense as well. A, has gone, is in the present perfect tense, which is used to talk about actions that happened in the past but have a connection to the present. B, went, is in the simple past tense, which is used to talk about actions that happened at a specific time in the past. C, is going, is in the present progressive tense, which is used to talk about actions that are happening now or that will happen in the near future. D, will go, is in the future tense, which is used to talk about actions that will happen in the future.

In this case, the speaker is talking about an action that happened in the past, so the correct verb tense is the simple past tense.

Women migrants from West Bengal may face vulnerabilities such as exploitation and low wages, limited access to social services, and gender-based discrimination.

* Exploitation and low wages: Women migrants are often vulnerable to exploitation and low wages. They may be forced to work in dangerous or unhealthy conditions, and they may not be paid the same as men for the same work.
* Limited access to social services: Women migrants may also have limited access to social services, such as healthcare, education, and housing. This can make it difficult for them to meet their basic needs and to support their families.
* Gender-based discrimination: Women migrants may also face gender-based discrimination. They may be subjected to violence, harassment, and abuse. They may also be denied equal opportunities in education, employment, and housing.

These vulnerabilities can have a significant impact on the lives of women migrants. They can make it difficult for them to earn a living, to care for their families, and to live in safety and security. It is important to address these vulnerabilities and to ensure that women migrants have the same rights and opportunities as men.

The correct answer is A.

The atmosphere is divided into five main layers: the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The troposphere is the lowest layer and extends from the surface of the Earth to an average height of about 12 kilometers (7.5 miles). The stratosphere extends from the top of the troposphere to an average height of about 50 kilometers (31 miles). The mesosphere extends from the top of the stratosphere to an average height of about 85 kilometers (53 miles). The thermosphere extends from the top of the mesosphere to an average height of about 600 kilometers (373 miles). The exosphere extends from the top of the thermosphere to an average height of about 10,000 kilometers (6,200 miles).

The troposphere is the layer of the atmosphere that contains most of the Earth's weather. The stratosphere is the layer of the atmosphere that contains the ozone layer. The mesosphere is the layer of the atmosphere that is coldest. The thermosphere is the layer of the atmosphere that is hottest. The exosphere is the layer of the atmosphere that is closest to space.

The tropopause is the boundary between the troposphere and the stratosphere. The stratopause is the boundary between the stratosphere and the mesosphere. The mesopause is the boundary between the mesosphere and the thermosphere. The thermopause is the boundary between the thermosphere and the exosphere.

The troposphere, stratosphere, mesosphere, thermosphere, and exosphere are all important layers of the atmosphere. Each layer plays a different role in the Earth's climate and weather.

The correct answer is: B. Leisure

The word "leisure" means time free from work or other obligations, which can be used for rest, relaxation, or amusement. It is derived from the Old French word "leisir," which means "to be allowed."

The correct answer is: A. Concave mirror

A concave mirror is a curved mirror that bulges inward at the center. The reflecting surface is on the inside of the curve. Concave mirrors can be used to create real or virtual images, and they can also be used to magnify or reduce objects.

When you look into a concave mirror, you will see an image of yourself that is smaller than you are. This is because the concave mirror reflects light rays in such a way that they converge in front of the mirror. The image is virtual, upright, and smaller than the object.

A convex mirror is a curved mirror that bulges outward at the center. The reflecting surface is on the outside of the curve. Convex mirrors always produce virtual images that are upright and smaller than the object.

A plano-concave mirror is a combination of a flat mirror and a concave mirror. The flat mirror is on one side of the mirror, and the concave mirror is on the other side. The reflecting surface of the concave mirror is on the inside of the curve. Plano-concave mirrors always produce virtual images that are upright and smaller than the object.

A plane mirror is a flat mirror. Plane mirrors always produce virtual images that are upright and the same size as the object.

The correct answer is: B. Different elasticity of demand.

Price discrimination is a pricing strategy in which a company charges different prices for the same product or service to different groups of consumers. This is possible when the demand for the product or service is different in different markets.

If the demand for the product or service is the same in all markets, then the company will not be able to charge different prices without losing customers. This is because customers will simply buy the product or service from the market where it is being sold at the lower price.

However, if the demand for the product or service is different in different markets, then the company can charge different prices without losing customers. This is because customers in the market with the higher demand will be willing to pay a higher price for the product or service.

For example, a company that sells airline tickets may charge different prices for tickets to the same destination depending on when the ticket is purchased. Tickets purchased closer to the date of travel are likely to be more expensive than tickets purchased further in advance. This is because the demand for airline tickets is higher closer to the date of travel.

Price discrimination can be a profitable strategy for companies. However, it is important to note that price discrimination can also lead to consumer dissatisfaction. This is because consumers in the market with the higher price may feel that they are being treated unfairly.

In conclusion, price discrimination is possible and profitable when the two markets have different elasticity of demand. This is because the demand for the product or service is different in different markets, and customers in the market with the higher demand are willing to pay a higher price for the product or service.

Nija Griha Nija Bhumi is a multi-purpose project which provides the landless agricultural labourers five decimals of land to make house and do farming. This ensures food security.

The probability density function (PDF) of a continuous random variable $X$ is a function $f_X(x)$ that gives the probability that $X$ takes on a value between $x$ and $x + dx$, for an infinitesimally small value of $dx$. The total probability that $X$ takes on any value is 1, so the PDF must satisfy the condition $int_mathbb{R} f_X(x) dx = 1$.

In this case, the PDF is given by

$$f_X(x) = begin{cases} K(5x - 2x^2) & text{if } 0 leq x leq 2 \ 0 & text{otherwise} end{cases}$$

The value of $K$ is not specified, but it can be found by integrating the PDF over the entire real line. This gives

$$1 = int_mathbb{R} f_X(x) dx = K int_0^2 (5x - 2x^2) dx = K left[ frac{5x^2}{2} - frac{2x^3}{3} right]_0^2 = 4K$$

Therefore, $K = frac{1}{4}$.

The probability that $X > 1$ is the area under the PDF to the right of $x = 1$. This area can be found by integrating the PDF from $1$ to $2$. This gives

$$P(X > 1) = int_1^2 f_X(x) dx = int_1^2 frac{1}{4} (5x - 2x^2) dx = frac{5x^2}{8} - frac{x^3}{12} bigg|_1^2 = frac{1}{8} - frac{1}{12} = boxed{frac{3}{14}}$$

The correct answer is (c).

Uttar Pradesh is the most populous state in India, with a population of over 200 million people. It is also the second-largest state in terms of area, after Rajasthan.

Girish Chandra Ghosh is considered as the Father of Modern Bengali stage.

The correct answer is (d).

A word is said to be symmetrical if it looks the same when reflected in a mirror. In other words, if you write the word on a piece of paper and then fold the paper in half so that the word lines up with itself, the two halves should be identical.

Of the four words given, only AMUMA is symmetrical. This is because all of the letters in AMUMA are the same, and they are all in the same order. When you reflect AMUMA in a mirror, the two halves of the word are identical.

The other three words are not symmetrical. In AXNXA, the X's are not in the same order on either side of the mirror. In CLOLC, the C's are not in the same order on either side of the mirror. And in AOMDE, the O's are not in the same order on either side of the mirror.

Therefore, the correct answer is (d).

The correct answer is: C. Only II is implicit.

The statement "As our business is expanding, we need to appoint more staff" does not imply that the present staff is not competent. It is possible that the present staff is competent, but the company needs to expand its operations and therefore needs to hire more staff.

The statement also does not imply that suitable persons to be taken as staff will be available. It is possible that the company will not be able to find suitable persons to hire, in which case it may need to reconsider its expansion plans.

The only assumption that is implicit in the statement is that more staff will further expand the business. This is because the company is only planning to hire more staff if it believes that this will help it to expand its operations.

The other two assumptions are not implicit in the statement. The statement does not say anything about the competence of the present staff, and it does not say anything about the availability of suitable persons to be hired.

The answer is B. Knight.

A nun is a woman who has dedicated her life to God and lives in a convent. A monk is a man who has dedicated his life to God and lives in a monastery. A priest is a man who has been ordained to perform religious ceremonies and rituals. A padre is a priest in the Catholic Church.

A knight is a man who is a member of the military and is skilled in the use of weapons. Knights are often associated with chivalry and the Crusades.

The word "knight" is different from the rest of the words in the list because it is the only word that does not refer to a religious figure.

The correct answer is A. a.

An LLB (Legum Baccalaureus) is a first professional law degree that is awarded by universities in many common law jurisdictions. It is the first of two degrees required to become a lawyer in most jurisdictions. The second degree is a postgraduate law degree, such as a Juris Doctor (JD) or Bachelor of Civil Law (BCL).

The word "a" is used before a singular noun that is not specific. In this case, the noun is "LLB degree". The LLB degree is a general degree that can be awarded by any university that offers a law program. Therefore, it is not specific to any particular university or program.

The words "an" and "the" are used before singular nouns that are specific. For example, if the question was "She graduated with an LLB degree from Harvard University", then the answer would be "an". This is because the LLB degree from Harvard University is a specific degree that is awarded by a specific university.

The word "none of these" is not the correct answer because it does not refer to any of the options.

Salt Lake Stadium is also known as Yuba Bharati Krirangan. It is the largest stadium in India and the second largest football stadium in the world, in terms of capacity.

The north-west pacific region is the fourth largest fish exporting region in the world, accounting for 12% of global fish exports in 2020. The top five fish exporting countries in the region are China, Japan, the United States, Canada, and South Korea. These countries export a variety of fish products, including tuna, salmon, shrimp, and crab.

The south-east asian region is the largest fish exporting region in the world because it has a long coastline and a large population. The region is also home to a number of important fish producing countries, such as Vietnam, Thailand, Indonesia, the Philippines, and Malaysia. These countries have developed strong fish processing and exporting industries.

The odd word in the given list is "again". The other words, "before", "now", "after", and "then", are all words that can be used to describe time. "Again" is not a word that can be used to describe time. It is a word that means "once more" or "repeatedly".

Here are some examples of how the other words can be used to describe time:

• Before: I went to the store before I went home.
• Now: I am at home now.
• After: I will go to the park after I eat dinner.
• Then: I went to the store, and then I went home.

The correct answer is C. Source.

The frequency of a sound wave is the number of waves that pass a given point in a given amount of time. It is measured in hertz (Hz), which is equal to one wave per second. The frequency of a sound wave is determined by the source of the sound. For example, a high-pitched sound has a higher frequency than a low-pitched sound.

Amplitude is the height of a wave. It is measured in meters. The amplitude of a sound wave does not affect its frequency.

Speed is the distance a wave travels in a given amount of time. It is measured in meters per second. The speed of a sound wave depends on the medium through which it is traveling. For example, sound travels faster through air than through water.

Medium is the substance through which a wave travels. Sound waves can travel through solids, liquids, and gases. The medium does not affect the frequency of a sound wave.

The correct answer is (c) 60%.

Road transport is the most important mode of transport in India, accounting for 60% of the total transport. This is due to a number of factors, including the country's large population, its vast geographical area, and the relatively low cost of road transport.

Road transport is also the most convenient mode of transport in India, as it provides access to even the remotest parts of the country. It is also the most flexible mode of transport, as it can be used to carry both passengers and goods.

However, road transport also has a number of disadvantages. It is a major source of air pollution, and it is also a major contributor to traffic congestion. In addition, road accidents are a major cause of death and injury in India.

Despite its disadvantages, road transport is likely to remain the most important mode of transport in India for the foreseeable future. This is due to the country's rapid economic growth, which is leading to an increase in the demand for transportation services. In addition, the government is investing heavily in road infrastructure, which is making road transport more efficient and affordable.

The other options are incorrect because they do not represent the actual share of road transport in total transport of India. Option (a) is incorrect because it is too high. Option (b) is incorrect because it is too low. Option (d) is incorrect because it is not a realistic estimate.

The correct answer is: A. Population increases arithmetically.

Thomas Malthus was an English economist and demographer who proposed the theory of population in his 1798 book An Essay on the Principle of Population. Malthus argued that population growth is exponential, while the growth of food production is linear. This means that population will eventually outstrip food production, leading to famine and disease.

Malthus's theory has been criticized for being too simplistic and for not taking into account technological advances in agriculture. However, it remains a influential theory in economics and demography.

Option B is incorrect because food production does not increase geometrically. Food production does increase, but it does so at a slower rate than population growth. This is because it takes time to develop new agricultural technologies and to bring them into widespread use.

Option C is incorrect because population does not increase geometrically. Population growth is exponential, but it does not increase at a constant rate. This is because the rate of population growth is affected by a number of factors, including birth rates, death rates, and migration.

Option D is incorrect because both A and B are incorrect.

The correct answer is C. Rationality.

Revealed preference analysis is a method of economic analysis that uses observed market data to infer the preferences of consumers. The basic idea is that if a consumer chooses to buy good A instead of good B, then they must prefer good A to good B. This assumption is known as weak ordering.

The other three assumptions are all necessary for revealed preference analysis to be valid. Consistency means that if a consumer chooses to buy good A instead of good B, and then chooses to buy good B instead of good C, then they must also prefer good A to good C. Transitivity means that if a consumer prefers good A to good B, and they also prefer good B to good C, then they must prefer good A to good C. Rationality means that a consumer will always choose the option that they prefer the most.

However, it is possible for a consumer to violate the rationality assumption without violating the other assumptions. For example, a consumer might choose to buy a good that they know is not the best option for them, simply because they are in a hurry or they do not have all the information. In this case, the consumer is still behaving in a consistent and transitive way, but they are not behaving rationally.

Therefore, the correct answer is C. Rationality.

The correct answer is: A) Labor unrest.

Labor unrest is a major challenge faced by industries in West Bengal in the past. The state has a long history of labor strikes and protests, which have disrupted production and caused economic losses. In recent years, the government has taken steps to address the issue of labor unrest, but it remains a major challenge for businesses operating in the state.

Excess government regulations can also be a challenge for businesses, but it is not as significant as labor unrest in West Bengal. The state has a complex regulatory environment, which can make it difficult for businesses to comply with all the rules and regulations. However, the government has been working to simplify the regulatory environment in recent years, which has made it easier for businesses to operate.

Abundant resources are not a challenge for businesses in West Bengal. The state has a wealth of natural resources, including coal, iron ore, and natural gas. These resources have attracted investment from businesses in the mining and manufacturing sectors.

A stable political environment is not a challenge for businesses in West Bengal. The state has a long history of political stability, which has created a favorable environment for businesses. The government has also been supportive of businesses, and has taken steps to improve the infrastructure and investment climate in the state.

In conclusion, the major challenge faced by industries in West Bengal in the past was labor unrest. The state has a long history of labor strikes and protests, which have disrupted production and caused economic losses. In recent years, the government has taken steps to address the issue of labor unrest, but it remains a major challenge for businesses operating in the state.

The correct answer is (b). Armed forces are not an essential element of a state in international law.

The Montevideo Convention on the Rights and Duties of States, which is a multilateral treaty adopted in 1933, sets out the four essential elements of a state in international law:

• a permanent population;
• a defined territory;
• a government;
• and the capacity to enter into relations with other states.

The correct answer is D. Attempting to stop entry of other firms in the market.

A monopoly is a market structure in which there is only one seller of a good or service. This means that the monopoly has a great deal of market power and can charge higher prices than would be possible in a competitive market. In addition, a monopoly may not produce as much output as would be produced in a competitive market, which can lead to higher prices and lower consumer surplus.

One way that a monopoly can maintain its market power is by attempting to stop entry of other firms into the market. This can be done through a variety of means, such as lobbying the government to pass laws that make it difficult for new firms to enter the market, or by engaging in predatory pricing, which is when a firm lowers its prices below cost in order to drive its competitors out of business.
