The correct answer is B. 1957.

Sputnik 1 was the first artificial Earth satellite. It was launched by the Soviet Union on October 4, 1957, and became the first human-made object to orbit the Earth. The satellite was a 585-kilogram (1,292 lb) polished metal sphere, 58 centimeters (23 in) in diameter, with four external radio antennas. It was launched from the Baikonur Cosmodrome in Kazakhstan, and orbited the Earth for 96.2 minutes before re-entering the atmosphere and burning up.

Sputnik 1's launch was a major milestone in the Space Race between the United States and the Soviet Union. It demonstrated that the Soviet Union had the capability to launch satellites into orbit, and it shocked the world. The launch of Sputnik 1 also led to the creation of NASA in the United States.

The other options are incorrect. Option A, 1955, is incorrect because Sputnik 1 was not launched until 1957. Option C, 1967, is incorrect because Sputnik 1 was launched in 1957, and option D, 1970, is incorrect because Sputnik 1 was launched in 1957.

The correct answer is: grows

The sentence is in the present tense, so the correct verb form is the present simple. The other options are incorrect because they are not in the present tense.

• Is growing is in the present progressive tense, which is used to describe an action that is happening right now.
• Has grown is in the present perfect tense, which is used to describe an action that happened in the past but has an effect on the present.
• Grow is the infinitive form of the verb, which is used to make verb phrases.

The sentence is about a place where no rain falls and no vegetation grows. This means that the action of growing is happening continuously, so the present simple tense is the correct tense to use.

The correct answer is C. towards.

The preposition "towards" is used to indicate the direction or position of something in relation to something else. In this case, the treatment is being given "towards" the subordinates. This means that the treatment is being directed at the subordinates, and it is having an effect on them.

The other options are not as appropriate in this context. The preposition "of" is used to indicate possession or ownership. The preposition "for" is used to indicate a purpose or destination. The preposition "to" is used to indicate a destination or recipient. The preposition "about" is used to indicate a topic or subject.

In conclusion, the correct answer is C. towards.

The correct answer is (d), Singapore.

An export processing zone (EPZ) is a special economic zone (SEZ) that is created to attract foreign direct investment (FDI) by offering businesses a range of incentives, such as tax breaks, duty-free imports, and streamlined customs procedures. EPZs are typically located in developing countries, and they have been credited with helping to boost economic growth and development in these countries.

The first EPZ in Asia was set up in 1965 in Singapore. The Singapore EPZ was a major success, and it helped to transform Singapore into a major economic hub. The EPZ was also a model for other EPZs that were set up in other Asian countries in the following decades.

The other options are incorrect. Al Hilai is a town in Qatar, Kandla is a port town in India, and Noida is a city in India. None of these places have EPZs.

The correct answer is: B. Period long enough to allow firms to change plant size and capacity.

The long run is a period of time long enough for firms to change all of their inputs, including plant size and capacity. In the long run, all inputs are variable, and firms can choose the optimal combination of inputs to produce their output.

The other options are incorrect because:

• Option A is too specific. The long run is not necessarily a period of three years or longer. It can be any period of time long enough for firms to change all of their inputs.
• Option C is too general. The long run is not simply a period of time long enough to allow firms to make economic decisions. It is a period of time long enough for firms to change all of their inputs.
• Option D is incorrect. The long run does not necessarily affect larger firms more than smaller firms. It can affect all firms equally, depending on the specific circumstances.

The correct answer is D. Relative density has no unit. It is a dimensionless quantity. It is defined as the ratio of the density of a substance to the density of a reference substance. The reference substance is usually water, which has a density of 1 g/cm3 or 1000 kg/m3. Relative density is often used to compare the densities of different substances. For example, the relative density of gold is 19.3, which means that gold is 19.3 times denser than water.

Option A is incorrect because kilograms per meter (kg/m) is the unit of mass per unit length. Option B is incorrect because kilograms per square meter (kg/m2) is the unit of mass per unit area. Option C is incorrect because kilograms per cubic meter (kg/m3) is the unit of mass per unit volume.

The correct answer is Metaphase.

In metaphase, the chromosomes are aligned at the center of the cell. This is the best time to see the shape of the chromosomes because they are condensed and easy to see.

In prophase, the chromosomes are still long and thin, and they are not easy to see.

In anaphase, the chromosomes are pulled apart by the spindle fibers. This is a very dynamic process, and it is difficult to see the individual chromosomes.

In telophase, the chromosomes decondense and become long and thin again. This is not a good time to see the shape of the chromosomes.

The correct answer is: D. Continue to operate as long as it covers its variable cost.

A perfectly competitive firm is a price taker, which means that it has no control over the market price of its product. If the market price is below the firm's average variable cost, then the firm will shut down in the short run. This is because the firm will lose more money by producing and selling its product than it would by simply shutting down and paying its fixed costs. However, if the market price is above the firm's average variable cost, then the firm will continue to operate in the short run. This is because the firm will make a profit by producing and selling its product, even though it will still be incurring some losses.

Here is a brief explanation of each option:

• Reduce the size of its plant to lower fixed costs. This option is not correct because a perfectly competitive firm has no control over its fixed costs. Fixed costs are costs that do not change in the short run, regardless of the level of output. For example, a firm's rent is a fixed cost. If the firm reduces the size of its plant, it will still have to pay its rent, even if it is not producing any output.
• Raise the price of its product. This option is not correct because a perfectly competitive firm is a price taker. This means that the firm has no control over the market price of its product. The market price is determined by the interaction of supply and demand in the market.
• Shut down. This option is correct if the market price is below the firm's average variable cost. This is because the firm will lose more money by producing and selling its product than it would by simply shutting down and paying its fixed costs.
• Continue to operate as long as it covers its variable cost. This option is correct if the market price is above the firm's average variable cost. This is because the firm will make a profit by producing and selling its product, even though it will still be incurring some losses.

The correct answer is A. Robbins.

Lionel Robbins was a British economist who is best known for his work on the foundations of economic theory. He is also known for his views on the role of economics in society, which he argued should be neutral between ends. This means that economics should not be used to promote any particular set of values or goals, but should instead be used to provide a framework for understanding the choices that individuals and societies make.

Marshall was an English economist who is considered one of the founders of neoclassical economics. He is best known for his work on the theory of value and distribution. Marshall argued that economics should be based on the study of human behavior, and that it should be used to improve the welfare of society.

Pigou was an English economist who is best known for his work on welfare economics. He argued that the government should intervene in the economy to correct market failures and promote economic efficiency.

Adam Smith was a Scottish economist and philosopher who is considered the father of modern economics. He is best known for his work on the theory of free markets, which he argued would lead to the greatest good for the greatest number of people.

In conclusion, Robbins was the economist who expressed the view that 'Economics should be neutral between ends'. This means that economics should not be used to promote any particular set of values or goals, but should instead be used to provide a framework for understanding the choices that individuals and societies make.

The correct answer is: B. Strong Nuclear Force

The strong nuclear force is the fourth fundamental force (not including gravity) binding quarks into hadrons. It is the strongest of the four fundamental forces, but it has a very short range. The strong force is responsible for the stability of atomic nuclei by holding the protons and neutrons together.

The weak nuclear force is responsible for radioactive decay. It is much weaker than the strong nuclear force, but it has a longer range. The weak force is responsible for the decay of neutrons into protons, electrons, and antineutrinos.

The electromagnetic force is responsible for the attraction and repulsion of charged particles. It is much weaker than the strong nuclear force, but it has a much longer range. The electromagnetic force is responsible for the chemical bonds that hold atoms together, and it is also responsible for light and electricity.

The gravitational force is the weakest of the four fundamental forces, but it has an infinite range. The gravitational force is responsible for the attraction of all objects with mass. It is the force that keeps the Earth in orbit around the Sun, and it is also the force that keeps us on the ground.

I hope this helps! Let me know if you have any other questions.

The correct answer is B. Fall.

A decrease in demand means that consumers are willing and able to buy less of a good or service at any given price. This causes the demand curve to shift to the left, as shown in the diagram below.

[Diagram of a demand curve shifting to the left]

The equilibrium price is the price at which the quantity demanded equals the quantity supplied. When the demand curve shifts to the left, the equilibrium price falls. This is because at the old equilibrium price, there is now excess supply of the good or service. Producers will lower their prices in order to sell their goods, and the price will continue to fall until the quantity demanded equals the quantity supplied.

Option A is incorrect because a decrease in demand causes the equilibrium price to fall, not rise. Option C is incorrect because the equilibrium price will change, not remain constant. Option D is incorrect because the change in the equilibrium price is determinate, not indeterminate.

The odd one out is B. Good : Bad.

All the other options are opposites of each other.

• Valley : Depth - A valley is a low-lying area between hills or mountains, while depth is the distance from the top of something to the bottom.
• High : Low - High is the opposite of low, meaning above or at a great distance from the ground, while low is the opposite of high, meaning below or at a short distance from the ground.
• Black : White - Black is the opposite of white, meaning the darkest color of all, while white is the opposite of black, meaning the lightest color of all.

However, good and bad are not opposites. Good is a positive quality, while bad is a negative quality. They are not mutually exclusive, meaning that something can be both good and bad at the same time. For example, a person might be a good friend but a bad driver.

The correct answer is D. Sister-in-law.

Namrata's father has only one son, and Ketan is the son of that son. This means that Ketan is Namrata's nephew. Namrata's nephew's mother is Namrata's sister-in-law.

Here is a diagram to illustrate the relationship:

[Diagram of Namrata, her father, her brother, Ketan, and Ketan's mother]

• Namrata's father is the only parent of Namrata's brother.
• Ketan is the son of Namrata's brother.
• Ketan's mother is the wife of Namrata's brother.

• Option A is incorrect because Namrata is not Ketan's daughter.
• Option B is incorrect because Namrata is not Ketan's aunt.
• Option C is incorrect because Namrata is not Ketan's sister.
• Option E is incorrect because Ketan's mother is related to Namrata.

The correct answer is B. Respiration.

Respiration is the process by which organisms convert food into energy. This process takes place in the cells of the body and involves the breakdown of glucose, a type of sugar, into carbon dioxide and water. The energy released during respiration is used to power the cell's activities.

Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into glucose and oxygen. This process takes place in the leaves of plants and is essential for life on Earth.

Reproduction is the process by which organisms produce offspring. This process can take place sexually or asexually. Sexual reproduction involves the fusion of two gametes, or sex cells, to produce a new organism. Asexual reproduction does not involve the fusion of gametes and can occur in a variety of ways, such as budding, fragmentation, or parthenogenesis.

Excretion is the process by which organisms remove waste products from the body. This process takes place in the kidneys and involves the filtration of blood to remove waste products such as urea, creatinine, and uric acid. The waste products are then excreted in the urine.

The correct answer is: A. Marginal productivity theory of wages.

John Stuart Mill was an English philosopher, economist, and civil servant. He was an influential contributor to social theory, political theory, and political economy. He is widely considered one of the most influential thinkers in the history of classical liberalism.

The marginal productivity theory of wages is a theory of wages that states that the wage rate for any type of labor is determined by the marginal productivity of that labor. In other words, the wage rate is equal to the value of the additional output that a worker produces.

Mill was one of the first economists to develop the marginal productivity theory of wages. He argued that the wage rate is determined by the marginal productivity of labor because employers are only willing to pay workers as much as they are worth. If workers are paid more than their marginal productivity, then employers will lose money and will eventually go out of business. On the other hand, if workers are paid less than their marginal productivity, then employers will be able to make more money by hiring more workers. This will drive up the wage rate until it reaches the point where the marginal productivity of labor is equal to the wage rate.

The marginal productivity theory of wages is a widely accepted theory of wages. It is used to explain the wages of workers in a variety of industries and occupations. It is also used to explain the differences in wages between different workers.

The other options are incorrect because they are not theories of wages that are associated with John Stuart Mill.

• The wages-fund theory is a theory of wages that states that the wage rate is determined by the amount of capital that is available to pay wages. This theory was popular in the 19th century, but it is no longer widely accepted.
• The subsistence theory of wages is a theory of wages that states that the wage rate is determined by the cost of living. This theory was popular in the 18th century, but it is no longer widely accepted.
• The iron law of wages is a theory of wages that states that the wage rate will always tend to fall to the subsistence level. This theory was popular in the 19th century, but it is no longer widely accepted.

The correct answer is: A) Blocks cold northerly winds.

The Himalayas act as a barrier to cold northerly winds from Central Asia, which helps to keep the climate of West Bengal relatively warm and humid. The Himalayas also cause a rain shadow effect, which means that the eastern side of the mountains receives much more rainfall than the western side. This is because the moisture-laden air from the Indian Ocean is forced to rise up over the Himalayas, causing it to cool and condense. The resulting rain falls on the eastern side of the mountains, while the western side is left relatively dry.

Option B is incorrect because the Himalayas do not create a rain shadow effect on the western side of the mountains. Option C is incorrect because the Himalayas help to keep the climate of West Bengal relatively warm and humid. Option D is incorrect because the Himalayas do not reduce humidity levels.

The correct answer is: C. The demand curve is a downward curve.

The law of demand states that, all other things being equal, the quantity demanded of a good or service will decrease as the price of that good or service increases. This is because, as the price of a good or service increases, consumers will have less money to spend on other goods and services, so they will demand less of the good or service whose price has increased.

The demand curve is a graphical representation of the law of demand. It shows the relationship between the price of a good or service and the quantity demanded of that good or service. The demand curve is always downward-sloping, which means that the quantity demanded of a good or service decreases as the price of that good or service increases.

Option A is incorrect because the demand curve is always downward-sloping, not upward-sloping.

Option B is incorrect because the demand curve is a curve, not a straight line.

Option D is incorrect because the demand curve is not a vertical line. A vertical line would mean that the quantity demanded of a good or service is not affected by the price of that good or service, which is not the case.

The correct answer is: B. Ribosomes.

Ribosomes are organelles that are found in the cytoplasm of cells. They are responsible for protein synthesis, which is the process of building proteins from amino acids. Proteins are essential for all living things, and they are involved in a wide variety of functions, including cell structure, metabolism, and gene expression.

The nucleus is the control center of the cell. It contains the cell's DNA, which is the blueprint for all of the cell's proteins. However, the nucleus does not actually synthesize proteins. Instead, it sends the information encoded in DNA to the ribosomes, which are the organelles that actually build proteins.

The cell wall is a rigid structure that surrounds the cell membrane. It is made of cellulose, a type of carbohydrate. The cell wall provides support and protection for the cell. However, it does not play a role in protein synthesis.

The correct answer is D. All of the above are major challenges to reducing gender inequality in West Bengal.

* Low female labor force participation: The female labor force participation rate in West Bengal is 22.5%, which is lower than the national average of 23.3%. This means that fewer women in West Bengal are participating in the workforce than men. There are a number of reasons for this, including social norms that discourage women from working outside the home, lack of access to education and training, and discrimination in the workplace.
* High maternal mortality rate: The maternal mortality rate in West Bengal is 170 per 100,000 live births, which is higher than the national average of 120 per 100,000 live births. This means that for every 100,000 women who give birth in West Bengal, 170 of them will die. There are a number of reasons for this, including lack of access to quality healthcare, poor nutrition, and high rates of anemia among pregnant women.
* Limited access to education for girls: The literacy rate for girls in West Bengal is 72.3%, which is lower than the national average of 74.0%. This means that fewer girls in West Bengal are literate than boys. There are a number of reasons for this, including social norms that discourage girls from going to school, lack of access to schools, and poverty.

These are just some of the major challenges to reducing gender inequality in West Bengal. There are many other challenges, such as violence against women, discrimination in the workplace, and lack of representation in decision-making bodies. It is important to address all of these challenges in order to achieve gender equality in West Bengal.

The correct answer is A. 25% change in total revenue.

Unitary elastic demand means that the percentage change in quantity demanded is equal to the percentage change in price. In other words, if the price increases by 25%, the quantity demanded will decrease by 25%. This will result in a 25% change in total revenue, because the price and quantity demanded are changing by the same percentage.

Option B is incorrect because a 25% increase in price will not result in no change in quantity demanded. If demand is unitary elastic, a 25% increase in price will result in a 25% decrease in quantity demanded.

Option C is incorrect because a 25% increase in price will not result in a 1% decrease in quantity demanded. If demand is unitary elastic, a 25% increase in price will result in a 25% decrease in quantity demanded.

Option D is incorrect because a 25% increase in price will not result in a 25% decrease in quantity demanded. If demand is unitary elastic, a 25% increase in price will result in a 25% decrease in quantity demanded.

The speed of sound in water is about 1,500 m/s. The speed of sound in air is about 343 m/s. The speed of sound in glass is about 5,000 m/s. The speed of sound in glycerine is about 1,200 m/s.

Therefore, the speed of sound is greatest in water.

• Sound travels faster in solids than in liquids because the molecules in a solid are closer together than the molecules in a liquid. This means that the sound waves can travel from one molecule to the next more easily in a solid than in a liquid.
• Sound travels faster in liquids than in gases because the molecules in a liquid are closer together than the molecules in a gas. This means that the sound waves can travel from one molecule to the next more easily in a liquid than in a gas.
• Sound travels slowest in gases because the molecules in a gas are far apart from each other. This means that the sound waves have to travel a longer distance between each molecule, which makes them travel slower.

The correct answer is: **C) Social security**

The Banglar Manush scheme is a social security scheme launched by the Government of West Bengal in 2016. The scheme aims to provide financial assistance to the poor and vulnerable sections of the society.

* Option D: Housing. The Banglar Manush scheme is not a housing scheme. It is a social security scheme.

The correct answer is A. A single diode.

A NOT gate is a logic gate that inverts its input. This means that if the input is 1, the output will be 0, and if the input is 0, the output will be 1.

A diode is a semiconductor device that allows current to flow in one direction only. When a voltage is applied to a diode, the current will flow from the anode to the cathode. If the voltage is applied in the opposite direction, the current will not flow.

A NOT gate can be implemented by using a single diode. The diode is connected in series with a resistor. The input voltage is applied to the anode of the diode, and the output voltage is taken from the cathode of the diode. When the input voltage is high, the diode will conduct and the output voltage will be low. When the input voltage is low, the diode will not conduct and the output voltage will be high.

Options B, C, and D are incorrect because they cannot implement a NOT gate. A NOT gate requires a device that can invert its input, and a single resistor, a single transistor, or two diodes cannot do this.

The correct answer is D. The law of conservation of energy.

The first law of thermodynamics states that energy can neither be created nor destroyed, only transferred from one form to another. This means that the total amount of energy in a closed system remains constant.

Charles's law states that the volume of a gas is directly proportional to its temperature, if pressure is kept constant.

Newton's law of cooling states that the rate of heat transfer between two objects is proportional to the difference in their temperatures.

The law of heat exchange states that heat always flows from a hotter object to a colder object.

All of these laws are related to the first law of thermodynamics, but they are not the same thing. The first law of thermodynamics is a more general law that encompasses all of these other laws.

The correct answer is: Only conclusion II follows.

The statement "Adversity makes a man wise" does not necessarily mean that the poor are wise. It is possible for someone to experience adversity and not become wise, and it is also possible for someone to become wise without experiencing adversity.

The statement does, however, suggest that man learns from bitter experience. This is because adversity can be a source of learning and growth. When we experience adversity, we are forced to confront our weaknesses and limitations. We may also be forced to make difficult choices. These experiences can help us to develop wisdom and resilience.

Therefore, only conclusion II follows.

The Indian National Army (INA) was formed by Subhas Chandra Bose.

A. Mahatma Gandhi was a leader of the Indian independence movement who employed nonviolent civil disobedience to lead India to independence from British rule. He is internationally honored for his philosophy of nonviolence and his leadership of the Indian independence movement.

D. Sardar Vallabhbhai Patel was an Indian politician who played a leading role in the Indian independence movement. He was a close associate of Mahatma Gandhi and Jawaharlal Nehru. After India's independence, Patel was the first Deputy Prime Minister of India and the Minister of Home Affairs. He is known as the "Iron Man of India" for his role in unifying the princely states into the Indian Union.

The correct answer is: B. Pangurian : Porcupine

A colubrine is a snake, and a pangurian is a porcupine. Both colubrine and pangurian are names of animals that belong to a specific group. Colubrine snakes are all members of the family Colubridae, while pangurians are all members of the family Hystricidae.

A lupine is a plant, and a wolf is an animal. Lupines and wolves are not members of the same group. Lupines are plants, while wolves are animals.

A psittacine is a parrot, and ophiolatry is the worship of snakes. Psittacines and ophiolatry are not members of the same group. Psittacines are birds, while ophiolatry is a religious practice.

The correct answer is C. for.

• In is used to indicate a location or position inside something. For example, "The bracelet is in the box."
• On is used to indicate a location or position on top of something. For example, "The bracelet is on my wrist."
• For is used to indicate a purpose or goal. For example, "I am keen for the bracelet."
• With is used to indicate a relationship or association. For example, "I am keen with the bracelet."

In this case, the speaker is asking if the listener is interested in the bracelet. The correct answer is "for" because the listener is interested in the bracelet for a specific purpose, which is to wear it.

The correct answer is B) Xuanzang.

Xuanzang was a Chinese Buddhist monk who traveled to India in the 7th century CE. He left behind a detailed account of his travels, which includes descriptions of the people, places, and customs he encountered. His writings are an important source of information about India during the Gupta period.

Fa Xian was another Chinese Buddhist monk who traveled to India in the 5th century CE. He also left behind a detailed account of his travels, but his writings are not as comprehensive as Xuanzang's.

Yijing was a Chinese Buddhist monk who traveled to India in the 7th century CE. He was a contemporary of Xuanzang, but his travels took him to different parts of India. His writings are also an important source of information about India during the Gupta period.

However, Xuanzang's writings are considered to be more reliable than Fa Xian's and Yijing's, as he spent more time in India and traveled to more places. He also had a better command of the local language, which allowed him to interact with the people more easily.

Xuanzang's writings provide a valuable glimpse into the life and culture of India during the Gupta period. They are an important source of information for historians and scholars alike.

The correct answer is B. Gravitational Force.

Gravitational force is the force of attraction between any two bodies by virtue of their masses. It is the weakest of the four fundamental forces of nature, but it is the most important force on a large scale. The gravitational force between two objects is proportional to the product of their masses and inversely proportional to the square of the distance between them. This means that the more massive two objects are, the stronger the gravitational force between them, and the closer two objects are, the stronger the gravitational force between them.

The gravitational force is responsible for the Earth's orbit around the Sun, the Moon's orbit around the Earth, and the tides. It is also responsible for the formation of stars and planets.

The other options are incorrect.

• Option A, Electromagnetic Force, is the force that holds atoms together. It is a much stronger force than gravitational force.
• Option C, Centripetal Force, is the force that keeps an object moving in a circle. It is not a force of attraction.
• Option D, Nuclear Force, is the force that holds the nucleus of an atom together. It is a much stronger force than gravitational force.

Pandit Jawaharlal Nehru visited Dugadda in 1936 on the invitation of the Garhwal Congress Committee. He was accompanied by his daughter Indira Gandhi. The purpose of the visit was to address a public meeting and to assess the political situation in the region.

Nehru's visit was significant because it was the first time that a national leader had visited Dugadda. It was also a sign of the growing importance of the Garhwal region in the national political scene.

The meeting was attended by a large crowd of people from all over the Garhwal region. Nehru spoke about the importance of independence and the need for unity among the people of India. He also spoke about the need for social and economic reforms.

Nehru's visit was a major boost for the Garhwal Congress Committee. It helped to raise the profile of the party in the region and to increase its support base. It also helped to create a sense of unity and purpose among the people of Garhwal.

The other options are incorrect because they are not the years in which Pandit Jawaharlal Nehru visited Dugadda.

West Bengal Vidhan Sabha comprises 295 members of Legislative Assembly. It includes 294 members directly elected from single-seat constituencies and one nominated from the Anglo-Indian community.

The park is home to a variety of wildlife, including tigers, leopards, elephants, and deer. However, it is not famous for conservation of snow-leopard.

The correct answer is: Ordinal utility.

Ordinal utility is a concept in economics that states that consumers can rank their preferences for different goods and services, but they cannot assign specific numerical values to those preferences. This means that consumers can say that they prefer A to B, or that they are indifferent between A and B, but they cannot say that they prefer A to B by a factor of 2.

Ordinal utility is the basis for indifference curve analysis, which is a tool used to analyze consumer behavior. Indifference curves are curves that show all the combinations of goods and services that a consumer would be equally happy with. The slope of an indifference curve indicates the marginal rate of substitution, which is the rate at which a consumer is willing to trade one good for another.

The other options are incorrect because:

• Independent utility is the concept that the utility a consumer derives from one good is not affected by the consumption of another good. This is not a necessary assumption for indifference curve analysis.
• Cardinal utility is the concept that consumers can assign specific numerical values to their preferences for different goods and services. This is not a necessary assumption for indifference curve analysis.
• Diminishing marginal utility is the concept that the additional utility a consumer derives from consuming one more unit of a good declines as the consumer consumes more of that good. This is a concept that is often used in indifference curve analysis, but it is not a necessary assumption.

The correct answer is: A. MU is negative.

Marginal utility (MU) is the additional satisfaction or benefit that a consumer receives from consuming one more unit of a good or service. Total utility (TU) is the total satisfaction or benefit that a consumer receives from consuming all units of a good or service.

The MU curve will intersect the x-axis when MU is negative. This is because when MU is negative, the consumer is receiving less satisfaction from consuming an additional unit of the good or service. As a result, the consumer will not continue to consume the good or service, and the MU curve will intersect the x-axis.

Option B is incorrect because TU is maximum when MU is equal to zero. This is because when MU is equal to zero, the consumer is receiving the maximum amount of satisfaction from consuming the good or service. As a result, the consumer will not continue to consume the good or service, and the TU curve will reach a maximum point.

Option C is incorrect because both A and B are not always true. For example, if the consumer's MU is negative, but their TU is still increasing, then the MU curve will not intersect the x-axis.

Option D is incorrect because the MU curve will intersect the x-axis when MU is negative.

The correct answer is: C. The fundamental rights of the Indian Citizen

Article 31(A) of the Indian Constitution states that "No law providing for the acquisition by the State of any estate or of any rights therein or for the extinguishment or modification of any such rights shall be deemed to be void on the ground that it is inconsistent with any of the provisions of this Part (Part III of the Constitution, which deals with Fundamental Rights)".

This means that the State can acquire any property, even if it violates the fundamental rights of the owner, as long as the acquisition is done in accordance with the law.

The other options are incorrect because:

• Option A is incorrect because Article 31(A) does not deal with the State Government.
• Option B is incorrect because Article 31(A) does not deal with the Union Government.
• Option D is incorrect because Article 31(A) does not deal with the Directive Principles of State Policy.

The correct answer is: C. in

The preposition "in" is used to indicate a location inside a place. In this case, the hospital is a place, and the man is inside the hospital.

The other options are incorrect because they do not indicate a location inside a place.

• "With" is used to indicate a relationship between two people or things. In this case, the man is not in a relationship with the hospital.
• "At" is used to indicate a location at a specific point in time. In this case, the man is not at a specific point in time in the hospital.
• "To" is used to indicate a movement towards a place. In this case, the man is not moving towards the hospital.

The correct answer is: C. the most generous of all my friends.

The other options are incorrect because they do not accurately reflect the degree of generosity that the speaker is trying to convey. Option A, "more generous among all my friends," does not make it clear that the speaker's friend is the most generous of all their friends. Option B, "more generous of all my friends," is grammatically incorrect. Option D, "No improvement," is incorrect because the sentence could be improved by using the superlative form of the adjective "generous."

The superlative form of an adjective is used to compare one thing to all other things in a group. In this case, the speaker is comparing their friend to all of their other friends. The superlative form of "generous" is "most generous." Therefore, the correct sentence is: "He is the most generous of all my friends."

The correct answer is: A. International Volunteers Day

International Volunteers Day is a United Nations observance held annually on 5 December. It was established in 1985 by the United Nations General Assembly to recognize the efforts of volunteers in promoting peace and development.

World Soil Day is an international observance held annually on 5 December to raise awareness of the importance of soil and to promote sustainable soil management. It was established by the Food and Agriculture Organization of the United Nations in 2002.

Therefore, 5 December is celebrated as International Volunteers Day, not World Soil Day.

The correct answer is C. Methane and Air.

Methane is a colorless, odorless, and flammable gas that is found in natural gas and coal mines. When methane is mixed with air, it can form an explosive mixture. If a spark or flame ignites the mixture, it can cause a mine explosion.

Oxygen is a colorless, odorless, and tasteless gas that is essential for combustion. When oxygen is mixed with methane, it can increase the risk of a mine explosion.

Acetylene is a colorless, flammable gas that is used in welding and cutting. When acetylene is mixed with oxygen, it can form a highly explosive mixture. However, acetylene is not typically found in mines, so it is not a major cause of mine explosions.

Carbon dioxide is a colorless, odorless, and tasteless gas that is heavier than air. It is not flammable, but it can displace oxygen in the air, which can make it difficult to breathe. Carbon dioxide is not a major cause of mine explosions.

In conclusion, the correct answer is C. Methane and Air.

The correct answer is A. Apple.

A true fruit is a seed-bearing structure that develops from the ovary of a flowering plant, whereas a false fruit is a fruit that develops from other parts of the flower, such as the receptacle or the calyx.

Apples are false fruits because they develop from the receptacle of the flower, not from the ovary. The receptacle is the part of the flower that supports the other parts, such as the petals, sepals, and stamens. In apples, the receptacle becomes enlarged and fleshy, and it is this part that we eat. The true fruit of an apple is the small, hard core inside the apple, which contains the seeds.

Dates, grapes, and plums are all true fruits because they develop from the ovary of the flower. The ovary is the part of the flower that contains the ovules, which develop into seeds. In dates, grapes, and plums, the ovary becomes enlarged and fleshy, and it is this part that we eat. The seeds of these fruits are located inside the flesh of the fruit.

In conclusion, the correct answer to the question "Which among the following is not a true fruit?" is A. Apple.

The correct answer is B. impracticability.

Feasibility is the ability to be done or carried out successfully. Something that is impracticable is not possible or not practical to do.

A. unsuitability is not the correct answer because it means not appropriate or fitting for a particular purpose.

C. impropriety is not the correct answer because it means not in accordance with accepted standards of behavior.

D. cheapness is not the correct answer because it means low in price.

The correct answer is: B. Stimulated emission.

Stimulated emission is a process in which an atom or molecule in an excited state is stimulated by a photon of the same frequency to emit a second photon of the same frequency. This process is the basis of laser operation.

Blackbody radiation is the electromagnetic radiation emitted by a black body, an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence. The radiation is characterized by a continuous spectrum that peaks at a wavelength that depends on the temperature of the black body.

Planck's radiation law is a law that describes the spectral distribution of electromagnetic radiation emitted by a black body. The law was first proposed by Max Planck in 1900, and it is one of the most important laws in quantum mechanics.

Einstein oscillation is a process in which an atom or molecule in an excited state oscillates between two energy levels. The oscillation is caused by the absorption and emission of photons.

Stimulated emission is the only process that can amplify light. Blackbody radiation, Planck's radiation law, and Einstein oscillation are all processes that describe the emission of light, but they do not amplify light.

Option C is incorrect because the capital of British India was not shifted from Calcutta to Delhi in 1921. The capital was actually shifted in 1912.

Option D is incorrect because the capital of British India was not shifted from Calcutta to Delhi in 1931. The capital was actually shifted in 1912.

In uniform circular motion, the linear velocity is perpendicular to the radius vector. This is because the velocity is always tangent to the circle, and the radius vector is always pointing from the center of the circle to the point in question.

The radius is the distance from the center of the circle to any point on the circle. The force is the centripetal force that keeps the object moving in a circle. The momentum is the product of the mass of the object and its velocity.

The radius vector is a vector that points from the center of the circle to any point on the circle. The linear velocity is a vector that points in the direction of motion and has a magnitude equal to the distance traveled divided by the time it takes to travel that distance.

In uniform circular motion, the linear velocity is perpendicular to the radius vector because the velocity is always tangent to the circle, and the radius vector is always pointing from the center of the circle to the point in question.

The correct answer is (c).

The correct answer is A) Land reform and social justice.

The Zamindari system was a system of land tenure in India in which the Zamindars, or landlords, held large tracts of land and collected revenue from the peasants who worked the land. The system was abolished in 1950 by the Land Reforms Act, which redistributed land to the peasants and gave them greater control over their own lives.

The abolition of the Zamindari system was a significant step towards land reform and social justice. It helped to break the power of the landlords and gave the peasants a greater say in how their land was used. It also helped to improve the lives of the peasants by giving them more control over their own resources and by providing them with a greater opportunity to improve their economic status.

The other options are incorrect. Option B, Promoting industrialization, is incorrect because the abolition of the Zamindari system did not have a significant impact on industrialization. Option C, Strengthening the power of landlords, is incorrect because the abolition of the Zamindari system weakened the power of the landlords. Option D, Increasing agricultural productivity, is incorrect because the abolition of the Zamindari system did not have a significant impact on agricultural productivity.

The correct answer is connective tissue. Connective tissue is the most abundant tissue in the human body, making up about 50% of our body weight. It is found throughout the body, supporting and connecting other tissues and organs. Connective tissue is made up of cells, fibers, and ground substance. The cells in connective tissue are called fibroblasts. Fibroblasts produce the fibers and ground substance that make up connective tissue. The fibers in connective tissue are made of collagen and elastin. Collagen is a strong, tough fiber that provides strength and support. Elastin is a flexible fiber that allows connective tissue to stretch. The ground substance in connective tissue is a gel-like substance that helps to cushion and protect the tissues and organs.

Muscular tissue is the second most abundant tissue in the human body, making up about 40% of our body weight. It is found in the muscles that move our bones. Muscular tissue is made up of cells called muscle fibers. Muscle fibers are long, thin cells that can contract and relax. When muscle fibers contract, they pull on the bones, causing them to move.

Epithelial tissue is the third most abundant tissue in the human body, making up about 10% of our body weight. It is found on the surface of the body and in the lining of the organs and cavities. Epithelial tissue is made up of cells that are tightly packed together. The cells in epithelial tissue form a barrier that protects the body from the environment.

Nervous tissue is the least abundant tissue in the human body, making up about 1% of our body weight. It is found in the brain, spinal cord, and nerves. Nervous tissue is made up of cells called neurons. Neurons are cells that transmit nerve impulses. Nerve impulses are electrical signals that carry information throughout the body.

In conclusion, the most abundant tissue in the human body is connective tissue. Connective tissue is found throughout the body, supporting and connecting other tissues and organs. It is made up of cells, fibers, and ground substance.

Mayawati was the first and only woman to serve as the Chief Minister of Uttar Pradesh. She was elected to the position in 1995, 2002, and 2007. She is a member of the Bahujan Samaj Party (BSP) and is known for her strong support for the Dalit community.

The other options are incorrect because they are not the number of women who have served as the Chief Minister of Uttar Pradesh.

The correct answer is D. Hydrogen.

Greenhouse gases are gases that trap heat in the atmosphere, causing the planet to warm. The main greenhouse gases are water vapor, carbon dioxide, methane, nitrous oxide, and ozone.

Water vapor is the most abundant greenhouse gas in the atmosphere, but it is not the most important contributor to climate change. This is because water vapor is a short-lived gas, meaning that it does not stay in the atmosphere for very long. Carbon dioxide, on the other hand, is a long-lived gas, meaning that it can stay in the atmosphere for hundreds or even thousands of years.

Carbon dioxide is the second most abundant greenhouse gas in the atmosphere, and it is the most important contributor to climate change. This is because carbon dioxide is released into the atmosphere when fossil fuels are burned. Fossil fuels include coal, oil, and natural gas.

Methane is the third most abundant greenhouse gas in the atmosphere. It is released into the atmosphere from a variety of sources, including natural gas production, landfills, and agriculture.

Nitrous oxide is the fourth most abundant greenhouse gas in the atmosphere. It is released into the atmosphere from a variety of sources, including agriculture, fossil fuel combustion, and industrial processes.

Ozone is a greenhouse gas that is found in the stratosphere. The stratosphere is the layer of the atmosphere that is located above the troposphere. The troposphere is the layer of the atmosphere that is closest to the Earth's surface.

Hydrogen is not a greenhouse gas. This is because hydrogen is a light gas that escapes from the atmosphere very quickly.

The correct answer is C. impossible.

An ultra is a person who is extremely enthusiastic about a particular activity or cause. They are often passionate and vocal about their beliefs, and they may be seen as being over the top or even fanatical.

It would be very difficult for one person to have a quiet meal with a set of ultras around them. The ultras would likely be talking loudly and excitedly about their cause, and they may even be chanting or singing. This would make it very difficult for the person to have a conversation or enjoy their meal.

The other options are not as accurate. Option A, "unthinkable," is too strong. It is possible, though difficult, for one person to have a quiet meal with a set of ultras around them. Option B, "undesirable," is also too strong. It is not necessarily undesirable for one person to have a quiet meal with a set of ultras around them. It may be difficult, but it could also be an interesting or even enjoyable experience. Option D, "unbecoming," is not accurate because there is nothing wrong with one person having a quiet meal with a set of ultras around them.

The correct answer is: C. MR = 0.

Marginal revenue (MR) is the additional revenue that a firm earns from selling one more unit of its product. It is calculated by taking the derivative of total revenue (TR) with respect to quantity (Q).

Price elasticity of demand (e) is a measure of how responsive consumers are to changes in price. It is calculated by taking the percentage change in quantity demanded divided by the percentage change in price.

When e = 1, demand is unit elastic. This means that a 1% increase in price will lead to a 1% decrease in quantity demanded. In this case, marginal revenue will be equal to zero.

Here is a diagram that illustrates the relationship between price, marginal revenue, and elasticity of demand:

[Diagram of a demand curve with a price elasticity of demand of 1]

As you can see, when the price elasticity of demand is equal to 1, the demand curve is a straight line. This means that the percentage change in quantity demanded is equal to the percentage change in price. In this case, marginal revenue will be equal to zero.

Here is a brief explanation of each option:

• Option A: MR > 0. This is not possible when e = 1. When e = 1, demand is unit elastic. This means that a 1% increase in price will lead to a 1% decrease in quantity demanded. In this case, marginal revenue will be equal to zero.
• Option B: MR < 0. This is possible when e < 1. When e < 1, demand is inelastic. This means that a 1% increase in price will lead to a less than 1% decrease in quantity demanded. In this case, marginal revenue will be negative.
• Option C: MR = 0. This is possible when e = 1. When e = 1, demand is unit elastic. This means that a 1% increase in price will lead to a 1% decrease in quantity demanded. In this case, marginal revenue will be equal to zero.
• Option D: MR = 1. This is not possible. Marginal revenue can never be greater than price.

The correct answer is D. quietly.

Secretly means in a way that is not known to other people. Openly means in a way that is known to other people. Silently means in a way that does not make any noise. Quietly means in a way that is not loud.

Scarcely means almost not at all. Impolitely means in a way that is not respectful. Noisily means in a way that makes a lot of noise.

The answer D. quietly is the best choice because it is the closest antonym of the word "silently." The other options are not as close in meaning.

The probability of an event is the number of outcomes favorable to the event divided by the total number of possible outcomes. In this case, the event is "the sum is neither 8 nor 9." There are 36 possible outcomes when a die is thrown twice, and 10 of those outcomes are favorable to the event (namely, (1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (2,1), (2,2), (2,3), (2,4), (2,5), (2,6), (3,1), (3,2), (3,3), (3,4), (3,5), (3,6), (4,1), (4,2), (4,3), (4,4), (4,5), (4,6), (5,1), (5,2), (5,3), (5,4), (5,5), (5,6), (6,1), (6,2), (6,3), (6,4), (6,5), (6,6)). Therefore, the probability of the event is $frac{10}{36} = boxed{frac{5}{18}}$.

Option A is incorrect because it is the probability of the sum being 8. Option B is incorrect because it is the probability of the sum being 9. Option C is incorrect because it is the probability of the sum being 1, 2, 3, 4, 5, or 6. Option D is incorrect because it is the probability of the sum being anything other than 7.

The correct answer is: A. Alkine: CnH2n - 2, Alkyne: CnH2n, Alkane: CnH2n + 2

An alkane is a hydrocarbon that contains only carbon and hydrogen atoms and is saturated, meaning that it has all of its carbon atoms bonded to the maximum number of hydrogen atoms possible. The general formula for an alkane is CnH2n+2, where n is the number of carbon atoms in the molecule.

An alkene is a hydrocarbon that contains at least one double bond between carbon atoms. The general formula for an alkene is CnH2n, where n is the number of carbon atoms in the molecule.

An alkyne is a hydrocarbon that contains at least one triple bond between carbon atoms. The general formula for an alkyne is CnH2n-2, where n is the number of carbon atoms in the molecule.

Therefore, the correct match is:

• Alkine: CnH2n - 2

The correct answer is B. Beats.

Beats are a phenomenon that occurs when two sound waves of slightly different frequencies are heard at the same time. The waves interfere with each other, causing the loudness of the sound to alternate between louder and softer. The frequency of the beats is equal to the difference between the frequencies of the two waves.

Doppler effect is the change in frequency of a wave for an observer moving relative to the wave source. The Doppler effect is commonly heard as the change in pitch of a train whistle as it passes by.

Resonance is the phenomenon of a system oscillating with greater amplitude at some frequencies than at others. When an external force is applied at a resonant frequency, the system will oscillate with a larger amplitude than if the same force were applied at a different frequency.

Echo is the repetition of a sound caused by the reflection of sound waves from a surface. Echoes are often used to determine the distance to an object.

The correct answer is: B. rich, muddy and saturated with water.

Rice is a semiaquatic plant that grows best in flooded soils. The ideal soil for rice is a rich, muddy loam that is saturated with water. This type of soil provides the nutrients and moisture that rice plants need to thrive.

Clayey loam is a type of soil that is composed of a mixture of clay, silt, and sand. Clayey loams are typically rich in nutrients and have good drainage. However, they can be too heavy for rice plants to grow in.

Deep, loamy, well drained soil is a good type of soil for many plants, but it is not ideal for rice. Rice plants need to grow in flooded soils, so deep, loamy, well drained soil will not provide the necessary moisture.

Humus, rich in Fe and potash is a type of soil that is high in organic matter. Organic matter helps to improve soil structure and drainage. However, it does not provide the nutrients and moisture that rice plants need to thrive.

Therefore, the best type of soil for rice is a rich, muddy loam that is saturated with water.

The correct answer is A. Local minimum.

A local minimum is a point in a function's domain where the function's value is less than or equal to the values of the function in all neighboring points. In other words, a local minimum is a point where the function "bottoms out."

The function $f(x, y) = x^2 - y^2$ is defined on the entire plane $R^2$. To find the local minima of $f$, we need to find the points where its gradient is equal to zero. The gradient of $f$ is given by the vector $(2x, -2y)$.

The gradient of $f$ is equal to zero at the point $(0, 0)$. Therefore, $(0, 0)$ is a critical point of $f$. To determine whether $(0, 0)$ is a local minimum or a local maximum, we need to evaluate $f$ at points in the neighborhood of $(0, 0)$.

The value of $f$ at the point $(1, 0)$ is $1$. The value of $f$ at the point $(0, 1)$ is $-1$. Therefore, we can see that the value of $f$ decreases as we move away from $(0, 0)$ in the direction of $(1, 0)$, and the value of $f$ increases as we move away from $(0, 0)$ in the direction of $(0, 1)$. This tells us that $(0, 0)$ is a local minimum.

In conclusion, the point $(0, 0)$ is a local minimum of the function $f(x, y) = x^2 - y^2$.

The correct answer is D. No improvement.

The correct answer is: C. increase its electrical conductivity.

Suitable impurities are added to a semiconductor depending on its use. This is done in order to increase its electrical conductivity. The impurities are called dopants, and they can either increase or decrease the conductivity of the semiconductor.

Dopants that increase the conductivity are called donors. They donate electrons to the semiconductor, which makes it more conductive. Dopants that decrease the conductivity are called acceptors. They accept electrons from the semiconductor, which makes it less conductive.

The type of dopant that is used depends on the desired application of the semiconductor. For example, semiconductors that are used in transistors need to have a high conductivity, so they are doped with donors. Semiconductors that are used in solar cells need to have a low conductivity, so they are doped with acceptors.

Here is a brief explanation of each option:

• A. increase its life: This is not the main reason why impurities are added to semiconductors. The main reason is to increase their electrical conductivity. However, impurities can also affect the life of a semiconductor. For example, impurities can cause the semiconductor to degrade over time.
• B. enable it to withstand higher voltages: This is not the main reason why impurities are added to semiconductors. The main reason is to increase their electrical conductivity. However, impurities can also affect the ability of a semiconductor to withstand high voltages. For example, impurities can make a semiconductor more susceptible to breakdown.
• D. increase its electrical resistivity: This is not the main reason why impurities are added to semiconductors. The main reason is to increase their electrical conductivity. However, impurities can also affect the electrical resistivity of a semiconductor. For example, impurities can make a semiconductor more resistant to current flow.

The correct answer is: D. a-3, b-4, c-2, d-1

• Expansion in demand is a rightward shift of the demand curve. This means that at any given price, consumers are willing and able to buy more of the good.
• Contraction in demand is a leftward shift of the demand curve. This means that at any given price, consumers are willing and able to buy less of the good.
• Increase in demand is a movement along the demand curve to the right. This means that at the current price, consumers are willing and able to buy more of the good.
• Decrease in demand is a movement along the demand curve to the left. This means that at the current price, consumers are willing and able to buy less of the good.

Here are some examples of factors that can cause a change in demand:

• Changes in income: If people's incomes increase, they will typically be able and willing to buy more goods and services. This will lead to an increase in demand.
• Changes in the price of related goods: If the price of a substitute good decreases, consumers will be more likely to buy that good instead of the good in question. This will lead to a decrease in demand for the good in question.
• Changes in tastes and preferences: If people's tastes and preferences change, they may be more or less willing to buy a particular good. This will lead to an increase or decrease in demand, respectively.
• Changes in expectations: If people expect the price of a good to increase in the future, they may be more likely to buy it now. This will lead to an increase in demand. Conversely, if people expect the price of a good to decrease in the future, they may be less likely to buy it now. This will lead to a decrease in demand.

I hope this helps!

The correct answer is (a) Section 83.

The M'Naghten Rules are a set of rules used by English and other common law jurisdictions to determine whether the defendant was insane at the time of the crime and therefore not criminally responsible. The rules were established in 1843 by the House of Lords in the case of Daniel M'Naghten, who had shot and killed Edward Drummond, the private secretary of Prime Minister Robert Peel, believing that Drummond was the prime minister.

The M'Naghten Rules state that a person is not responsible for criminal conduct if at the time of such conduct, as a result of a defect of reason from disease of the mind, he did not know the nature and quality of the act he was doing; or, if he did know it, that he did not know that what he was doing was wrong.

Section 83 of the Indian Penal Code (IPC) is titled "Insanity". It states that "Nothing is an offence which is done by a person who, at the time of doing it, by reason of unsoundness of mind, is incapable of knowing the nature and quality of the act he is doing, or of knowing that he is doing what is wrong".

The M'Naghten Rules are similar to Section 83 of the IPC in that they both require the defendant to be suffering from a defect of reason from disease of the mind. However, the M'Naghten Rules are more restrictive than Section 83 in that they require the defendant to not know the nature and quality of the act he was doing, or to not know that what he was doing was wrong. Section 83, on the other hand, only requires the defendant to be incapable of knowing the nature and quality of the act he was doing, or of knowing that he is doing what is wrong.

The M'Naghten Rules have been criticized for being too narrow and for not taking into account the defendant's mental state at the time of the crime. Section 83 of the IPC has also been criticized for being too narrow, but it has been amended to include a provision that allows for the consideration of the defendant's mental state at the time of the crime.

The correct answer is: A) Tropical deciduous and mangrove forests.

West Bengal is a state in eastern India. It is located in the Ganges Delta, which is a large river delta formed by the Ganges, Brahmaputra, and Meghna rivers. The state has a tropical climate with a monsoon season that lasts from June to September.

The major forest types found in West Bengal are tropical deciduous forests and mangrove forests. Tropical deciduous forests are found in the drier parts of the state, while mangrove forests are found in the coastal areas.

Tropical deciduous forests are characterized by a seasonal rainfall pattern. During the monsoon season, the forests are lush and green. However, during the dry season, the trees shed their leaves and the forests become brown and dry.

Mangrove forests are found in the coastal areas of West Bengal. These forests are adapted to the salty water and muddy soil of the coastal environment. Mangrove forests are important for protecting the coastline from erosion and for providing a habitat for a variety of wildlife.

The other options are incorrect because they do not describe the major forest types found in West Bengal. Coniferous and temperate forests are found in the cooler parts of the world, while tropical evergreen forests are found in the wettest parts of the world. Thorn forests and scrublands are found in the drier parts of the world.

The Concurrent List includes subjects such as criminal law, marriage and divorce, and trade and commerce.

Forests are listed in the Union List. This means that the Union government has exclusive power to make laws on forests. The State government can only make laws on forests with the permission of the Union government.

The other options are incorrect. Option B, State, is incorrect because forests are listed in the Union List, not the State List. Option C, Global, is incorrect because forests are a national issue, not a global issue. Option D, Concurrent, is incorrect because forests are listed in the Union List, not the Concurrent List.

The correct answer is: Steam has latent heat of vaporisation.

When water boils, it turns into steam. This process requires energy, which is called the latent heat of vaporisation. The latent heat of vaporisation is the amount of energy required to change a liquid into a gas at a constant temperature.

The latent heat of vaporisation of water is 2260 kJ/kg. This means that 2260 kJ of energy is required to convert 1 kg of water into steam at 100°C.

When steam comes into contact with skin, it transfers this latent heat of vaporisation to the skin. This causes the skin to cool rapidly, which can lead to severe burns.

Water does not have a latent heat of vaporisation. This means that when water comes into contact with skin, it does not transfer as much energy to the skin as steam does. As a result, water is less likely to cause severe burns than steam.

The latent heat of fusion is the amount of energy required to melt a solid at a constant temperature. The latent heat of fusion of water is 334 kJ/kg. This means that 334 kJ of energy is required to melt 1 kg of ice at 0°C.

The latent heat of fusion does not play a role in the severity of burns caused by steam or water.

The correct answer is: A. Prologue : Epilogue

A propensity is a natural tendency or inclination to do something. A tendency is a natural inclination or disposition towards a particular action or course of behavior. A prologue is an introductory section or speech that comes before the main part of a book, play, or film. An epilogue is a concluding section or speech that comes after the main part of a book, play, or film.

In both cases, the first word describes something that comes before the second word. A propensity is a tendency that comes before an action, and a prologue is an introductory section that comes before the main part of a book.

The other options do not have the same relationship. A master is someone who has control over a slave, while audacity is boldness or daring. Conduct is behavior, while immorality is wickedness or evil.

The correct answer is (b) Patwadangar.

The other options are incorrect. To humiliate someone means to make them feel ashamed or embarrassed. To annoy someone means to make them feel irritated or frustrated. To act in a friendly way means to be kind and welcoming.

The correct answer is C. MC=MR.

A firm is in equilibrium when it is maximizing its profits. This occurs when the marginal revenue (MR) is equal to the marginal cost (MC). If MR>MC, the firm can increase its profits by producing more output. If MC>MR, the firm can increase its profits by producing less output. When MR=MC, the firm is producing the optimal amount of output and is making the maximum profit possible.

Option A is incorrect because if MR>MC, the firm can increase its profits by producing more output.

Option B is incorrect because if MC>MR, the firm can increase its profits by producing less output.

Option D is incorrect because MC=AC is the condition for a firm to be in a long-run equilibrium position. In the short run, a firm can be in equilibrium even if MC>AC.

The correct answer is D. The rent earned by a factor of production is equal to the difference between what this factor is currently earning and what this factor can obtain in its next best use.

Option A is incorrect because the rent earned by a factor of production is not equal to what this product can earn in its next best use. For example, if a farmer is currently earning $100 per acre for growing corn, and the next best use for that land is to grow soybeans, and the farmer could earn $90 per acre for growing soybeans, then the rent earned by the land is $10 per acre.

Option B is incorrect because the rent earned by a factor of production is not equal to the sum of this output accrues in its present use and what it can earn in its next best use. For example, if a farmer is currently earning $100 per acre for growing corn, and the next best use for that land is to grow soybeans, and the farmer could earn $90 per acre for growing soybeans, then the rent earned by the land is $10 per acre, not $190 per acre.

Option C is incorrect because the rent earned by a factor of production is not equal to his present earnings. For example, if a farmer is currently earning $100 per acre for growing corn, and the next best use for that land is to grow soybeans, and the farmer could earn $90 per acre for growing soybeans, then the rent earned by the land is $10 per acre, not $100 per acre.

The correct answer is: C. an upward shift of the demand curve.

When income rises, people have more money to spend on goods and services. This includes oranges. As a result, the demand for oranges will increase, and the demand curve will shift to the right.

Option A is incorrect because it describes a movement along the demand curve, not a shift in the demand curve. A movement along the demand curve occurs when the price of the good changes, while other things remain unchanged. In this case, the price of oranges is not changing, so there is no reason for the demand curve to shift.

Option B is incorrect because it describes a movement along the supply curve, not a shift in the supply curve. A movement along the supply curve occurs when the price of the good changes, while other things remain unchanged. In this case, the price of oranges is not changing, so there is no reason for the supply curve to shift.

Option D is incorrect because it describes a decrease in demand, not an increase in demand. A decrease in demand occurs when the price of the good decreases, while other things remain unchanged. In this case, the price of oranges is not changing, so there is no reason for the demand to decrease.

The correct answer is C. Platyhelminthes.

Platyhelminthes are a phylum of bilaterally symmetrical, unsegmented, soft-bodied invertebrates. They are the simplest animals with a true gastrointestinal tract. Platyhelminthes are found in both marine and freshwater habitats, and some are parasitic.

Nerve cells are found in all platyhelminthes, but nerves are not. Nerve cells are individual cells that are specialized for the transmission of nerve impulses. Nerves are bundles of nerve cells that are organized to transmit nerve impulses over long distances.

In platyhelminthes, nerve cells are scattered throughout the body. They are not organized into nerves. This means that nerve impulses cannot be transmitted over long distances in platyhelminthes.

The other options are incorrect because they all have nerves.

• Porifera are sponges. They do not have true tissues or organs, and they do not have nerve cells.
• Coelenterata are cnidarians. They have a simple nervous system that is organized into a nerve net.
• Nemathelminthes are roundworms. They have a well-developed nervous system that is organized into a central nervous system and a peripheral nervous system.

The correct answer is: A. PRSQ

3. But she did not.
4. We found it locked.
5. Even after that we waited for her quite a few days.
6. Eventually we reported to the police.

Option A, PRSQ, is the only option that follows this sequence of events. Option B, QPSR, is incorrect because it places the event in which the police are reported to before the event in which the police station is visited. Option C, QPRS, is incorrect because it places the event in which the police station is visited before the event in which the police are reported to. Option D, SQPR, is incorrect because it places the event in which the police station is visited before the event in which the police are reported to.
