The correct answer is: B. Both A and R are true but R is not a correct explanation of A

The Mughal court culture was a fusion of Indian and Persian cultures. It was not an antithesis of Indian culture. The Mughals adopted many Indian customs and traditions, such as the use of the Hindi language, the wearing of Indian clothes, and the celebration of Indian festivals. However, they also retained some Persian customs and traditions, such as the use of the Persian language, the wearing of Persian clothes, and the celebration of Persian festivals.

The Mughal court culture was a complex and sophisticated culture that was influenced by both Indian and Persian cultures. It was not an antithesis of Indian culture, but rather a fusion of two different cultures.

Here is a brief explanation of each option:

• A. Both A and R are true and R is the correct explanation of A

This option is incorrect because R is not a correct explanation of A. The Mughal court culture was a fusion of Indian and Persian cultures, not an antithesis of Indian culture.

• B. Both A and R are true but R is not a correct explanation of A

This option is correct because A and R are both true, but R is not a correct explanation of A.

• C. A is true but R is false

This option is incorrect because R is true. The Mughal court culture was a fusion of Indian and Persian cultures.

• D. A is false but R is true

This option is incorrect because A is true. The Mughal court culture was a fusion of Indian and Persian cultures.

The correct answer is (c), Punjab.

The training and visit system (T&V) is a system of agricultural extension that was developed in the 1960s by the Indian Council of Agricultural Research (ICAR). The system was designed to provide farmers with timely and accurate information on agricultural practices, and to help them improve their yields.

The T&V system was first adopted in Punjab in 1966. The system was successful in Punjab, and it was later adopted by other states in India. The T&V system has also been adopted by other countries, including Bangladesh, Indonesia, and the Philippines.

The T&V system is based on the following principles:

• Farmers should be the focus of agricultural extension.
• Extension workers should be trained in the latest agricultural practices.
• Extension workers should visit farmers regularly to provide them with information and advice.
• Extension workers should work closely with research scientists to ensure that they are providing farmers with the latest information.

The T&V system has been successful in increasing agricultural productivity in India and other countries. The system has also helped to improve the lives of farmers by providing them with the information and resources they need to improve their yields.

The other options are incorrect because they are not the first state which adopted the training and visit system of agricultural expansion.

The correct answer is: A) Boycott of British goods.

The Swadeshi movement was a socio-political movement in India that originated in Bengal in 1905. It was a protest against the partition of Bengal and British rule in India. The movement advocated for the boycott of British goods, the promotion of Indian-made goods, and the use of the Bengali language. The movement was successful in achieving some of its goals, such as the reversal of the partition of Bengal. However, it was ultimately unsuccessful in overthrowing British rule in India.

Option B, promotion of Western education, is incorrect because the Swadeshi movement was a reaction against Western influence in India. The movement's leaders believed that India should develop its own culture and economy, independent of Western influence.

Option C, adoption of British culture, is incorrect for the same reason as option B. The Swadeshi movement was a reaction against Westernization. The movement's leaders believed that India should preserve its own culture and values.

Option D, support for British rule, is incorrect because the Swadeshi movement was a protest against British rule. The movement's leaders believed that India should be an independent country.

• Option C: 95 Matters/Items. This is incorrect. The Seventh Schedule contains 97 matters, not 95.
• Option D: 91 Matters/Items. This is incorrect. The Seventh Schedule contains 97 matters, not 91.

The correct answer is: no article.

The word "European" is a common noun, which means it refers to a general class of people. Common nouns are not usually preceded by articles.

In this case, the speaker is not referring to a specific European person, but rather to any European person. Therefore, the article "a" or "an" would not be appropriate.

The article "the" would also be incorrect, because it is used to refer to a specific person or thing. In this case, the speaker is not referring to a specific European person, so the article "the" would not be appropriate.

Therefore, the correct answer is: no article.

The correct answer is: Article-33

Article 33 of the Indian Constitution deals with the power of Parliament to make laws which may restrict the rights conferred by Articles 19, 21 and 22 of the Constitution in the case of members of the Armed Forces, the Police and other forces charged with the maintenance of public order.

Article 19 guarantees six fundamental rights to the citizens of India, namely:

• Freedom of speech and expression
• Freedom to assemble peaceably and without arms
• Freedom to form associations or unions
• Freedom to move freely throughout the territory of India
• Freedom to reside and settle in any part of the territory of India
• Freedom to practice any profession, or to carry on any occupation, trade or business

Article 21 guarantees the right to life and personal liberty.

Article 22 guarantees protection against arrest and detention in certain cases.

Article 33 states that Parliament may by law make any provision for the modification of any of the provisions of Articles 19, 21 and 22 in the case of members of the Armed Forces, the Police and other forces charged with the maintenance of public order, if such modification is necessary or expedient in the interests of the sovereignty and integrity of India, the security of the State, friendly relations with foreign States, public order, decency or morality, or in relation to contempt of court, defamation or incitement to an offence.

Thus, under Article 33, the fundamental rights of defence forces' personnel can be restricted specially if such restriction is necessary or expedient in the interests of the sovereignty and integrity of India, the security of the State, friendly relations with foreign States, public order, decency or morality, or in relation to contempt of court, defamation or incitement to an offence.

The correct answer is: A) North Bengal.

The Rusty-spotted Cat is the smallest wild cat species in the world, with a body length of only 20 to 30 centimeters and a tail length of 15 to 20 centimeters. It is found in the forests of North Bengal, India. The cat is a solitary animal and is active at night. It feeds on small mammals, birds, and reptiles.

The Sundarbans is a delta region in the Bay of Bengal, shared by India and Bangladesh. It is the largest mangrove forest in the world and is home to a variety of wildlife, including the Bengal tiger. The Rarh Region is a region in central India that is known for its fertile land and its production of rice and wheat. Coastal West Bengal is a region in West Bengal, India that is located on the Bay of Bengal. It is a popular tourist destination, known for its beaches and its seafood.

The Rusty-spotted Cat is not found in the Sundarbans, the Rarh Region, or Coastal West Bengal. It is only found in the forests of North Bengal.

The correct answer is A. Unrestrained.

Incontinent means unable to control one's bowel or bladder movements. It can also mean lacking in self-control or restraint.

Unrestrained means not controlled or limited. It can also mean free from restraint or control.

Restless means unable to keep still or quiet. It can also mean feeling or showing a lack of peace or quiet.

Inconstant means not staying the same for long. It can also mean changing frequently or suddenly.

Uncertain means not sure or definite. It can also mean not having or showing confidence.

In this case, the word "incontinent" is most closely related to the word "unrestrained." Both words mean not being able to control oneself. In the case of incontinent, this means not being able to control one's bowel or bladder movements. In the case of unrestrained, this means not being able to control one's behavior.

The other words are not as closely related to "incontinent." Restless means unable to keep still or quiet, which is not the same as not being able to control oneself. Inconstant means not staying the same for long, which is not the same as not being able to control oneself. Uncertain means not sure or definite, which is not the same as not being able to control oneself.

The correct answer is: C. Should

The word "should" is used to express a recommendation or suggestion. In this case, the speaker is recommending that the listener ask the speaker's son to come home at once.

The word "while" is used to express a time relationship. In this case, the speaker is not expressing a time relationship between the listener meeting the speaker's son and the listener asking the speaker's son to come home.

The word "would" is used to express a possibility or willingness. In this case, the speaker is not expressing a possibility or willingness that the listener will meet the speaker's son in the market.

The correct answer is Newton's first law of motion.

Newton's first law of motion states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. This is also known as the law of inertia.

Newton's second law of motion states that the acceleration of an object is directly proportional to the net force acting on the object, and inversely proportional to the mass of the object. This is also known as the law of acceleration.

Newton's third law of motion states that for every action, there is an equal and opposite reaction. This is also known as the law of action and reaction.

There is no such thing as Newton's fourth law of motion.

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

The correct answer is D. Oil.

Viscous liquids are those that resist flow. The more viscous a liquid is, the slower it will flow. Water is a very low-viscosity liquid, while oil is a high-viscosity liquid. This is why water flows easily, while oil is more likely to drip or pour slowly.

Diesel is a type of fuel that is made from petroleum. It is a thick, dark liquid that is more viscous than water but less viscous than oil. Milk is a white liquid that is made from the milk of mammals. It is a low-viscosity liquid that flows easily.

Therefore, the most viscous liquid is oil.

The concept of martial law has been borrowed in India from the English Common Law. The English Common Law is a body of law that has developed over time through judicial decisions. It is not codified in a single document, but is instead found in the decisions of judges in individual cases.

The English Common Law was introduced to India by the British during the colonial period. It was used to govern the Indian people, and it continues to be used in India today.

The other options are incorrect. The Government of India Act, 1935 is a British law that was passed to govern India during the colonial period. The US Constitution is the supreme law of the United States of America. The Canadian Constitution is the supreme law of Canada.

The correct answer is B. You asked me why I was talking so much.

The sentence "You said to me, 'Why are you talking so much?'" is in the past tense. This means that the speaker is referring to an event that happened in the past. In this case, the speaker is asking the listener why they are talking so much.

The answer A is incorrect because the speaker is asking the listener why they are talking so much, not why someone else is talking so much.

A devotee is a person who is devoted to a particular person, activity, or cause. A scholar is a learned person, especially one who is an expert in a particular subject.

A hoodlum is a synonym for a criminal because both are people who break the law. A pioneer is not a synonym for a hoodlum because a pioneer is someone who explores or settles in a new area, while a hoodlum is someone who breaks the law. A devotee is not a synonym for a hoodlum because a devotee is someone who is devoted to a particular person, activity, or cause, while a hoodlum is someone who breaks the law. A scholar is not a synonym for a hoodlum because a scholar is a learned person, while a hoodlum is someone who breaks the law.

The correct answer is B. Beginning.

A synonym is a word that has the same or nearly the same meaning as another word. In this case, the word "genesis" means "the beginning or origin of something." The other options do not have the same meaning as "genesis."

In this case, the tree is not specific or unique. It is just one of many tall trees. Therefore, we do not need to use an article.

The other options are incorrect because they are all articles. Articles are used to specify or identify a particular thing. In this case, there is no need to specify or identify the tree, so we do not need to use an article.

WBSTC was established in 1989 and is responsible for operating bus service in the state.

The correct answer is A. Rectification.

A diode is a two-terminal electronic component that allows current to flow in one direction only. It is commonly used to convert alternating current (AC) to direct current (DC). This is done by allowing current to flow through the diode in the positive half-cycle of the AC waveform, but blocking current flow in the negative half-cycle.

Amplification is the process of increasing the amplitude of a signal. This can be done using a variety of electronic components, including transistors, vacuum tubes, and op-amps. Amplification is often used in audio and video systems to increase the volume of sound or the brightness of an image.

Modulation is the process of changing one signal (the carrier signal) in accordance with another signal (the modulating signal). This can be done by varying the amplitude, frequency, or phase of the carrier signal. Modulation is often used in telecommunications to transmit information over long distances.

Filtering is the process of removing unwanted components from a signal. This can be done using a variety of electronic components, including capacitors, inductors, and resistors. Filtering is often used in audio and video systems to remove noise and interference.

In conclusion, diodes are generally used for rectification. This is because they allow current to flow in one direction only, which is necessary for converting AC to DC.

The correct answer is: **D) Gram Sabha**

A Gram Sabha is the lowest tier of the Panchayati Raj system in West Bengal. It is a body of all the adult members of a village.

The correct answer is (c).

The percentage change in population in India from 1991 to 2001 was 21.3%, which is the lowest among the given options. The percentage change in population from 1971 to 1981 was 24.66%, from 1981 to 1991 was 23.85%, and from 2001 to 2011 was 17.64%.

The decline in the percentage change in population from 1991 to 2001 can be attributed to a number of factors, including:

• A decline in the fertility rate. The total fertility rate in India declined from 3.2 in 1991 to 2.6 in 2001. This means that women are having fewer children on average.
• An increase in the average age of marriage. The average age of marriage for women in India increased from 18.3 in 1991 to 20.9 in 2001. This means that women are having children later in life, which also contributes to a decline in the fertility rate.
• An increase in the use of contraception. The use of contraception in India increased from 46% in 1991 to 56% in 2001. This means that more couples are using contraception to prevent pregnancy, which also contributes to a decline in the fertility rate.

The decline in the percentage change in population is a positive development for India. It means that the country is becoming more developed and that people are having fewer children. This will put less strain on the country's resources and will help to improve the quality of life for all Indians.

The correct answer is A. frictional resistance.

Frictional resistance is the force that opposes the relative motion of two surfaces in contact. It is caused by the roughness of the surfaces and the adhesion between them. Frictional resistance is a major factor in determining the rate at which particles move.

Particle cohesive bonds are the forces that hold particles together. They are caused by the attraction between the particles' molecules. Particle cohesive bonds are important in determining the strength of a particle system.

Particle adhesive bonds are the forces that hold particles to a surface. They are caused by the attraction between the particles' molecules and the surface's molecules. Particle adhesive bonds are important in determining the adhesion of a particle system.

Momentum is the product of an object's mass and velocity. It is a measure of an object's inertia and its ability to resist changes in motion. Momentum is not a force and does not provide resistance to particles towards entertainment.

The correct answer is: A. Rate of substitution.

An isoquant is a curve that shows all the combinations of inputs that produce the same level of output. The rate of substitution is the amount of one input that must be given up to obtain an additional unit of another input while keeping output constant. The rate of substitution is not constant along an isoquant, but it is diminishing. This means that as you use more of one input, you have to give up less of the other input to keep output constant.

The rate of substitution is important because it tells us how much one input can be substituted for another without changing output. This information is useful for firms that are trying to find the least-cost combination of inputs to produce a given level of output.

The other options are incorrect because they do not affect the relationship of the isoquant curve line. The cost rate is the amount of money that a firm spends on inputs. The rate of production is the amount of output that a firm produces. Neither of these factors affect the relationship between the inputs and outputs that are represented by an isoquant.

The correct answer is: A. World Tuberculosis Day

World Tuberculosis Day is observed on 24 March every year to raise awareness about the global tuberculosis epidemic and to encourage efforts to prevent and treat this disease. Tuberculosis (TB) is a communicable disease caused by bacteria that primarily affect the lungs. It is spread through the air when an infected person coughs, sneezes, or speaks.

TB is a serious disease that can be fatal if not treated. However, it is also a curable disease. The World Health Organization (WHO) estimates that 10 million people fell ill with TB in 2019 and 1.4 million people died from the disease.

World Tuberculosis Day is an opportunity to highlight the importance of TB control and prevention. It is also a time to remember the victims of TB and to pay tribute to the health workers who are working to fight this disease.

The other options are incorrect because:

• International Day of Family is celebrated on 15 May.
• World Information Society Day is celebrated on 17 May.
• None of these options is a day that is celebrated on 20 March.

The answer is D. QN.

The other three options, A. GE, B. MK, and C. WU, are all pairs of letters that are next to each other on the alphabet. QN is not a pair of letters that are next to each other on the alphabet.

The correct answer is (d). Guanine is a purine base.

Purine bases are nitrogenous bases that are found in DNA and RNA. They are double-ringed molecules that are made up of a pyrimidine ring and an imidazole ring. Purines are essential for the structure and function of DNA and RNA. They are also involved in the regulation of gene expression.

Thymine, cytosine, and uracil are pyrimidine bases. They are single-ringed molecules that are made up of a pyrimidine ring and a pyrimidine ring. Pyrimidine bases are also found in DNA and RNA. They are involved in the formation of base pairs.

Thymine is complementary to adenine. Cytosine is complementary to guanine. Uracil is complementary to adenine in RNA.

Purine bases are larger than pyrimidine bases. They are also more hydrophobic than pyrimidine bases. This difference in size and hydrophobicity is important for the structure and function of DNA and RNA.

Purine bases are essential for life. They are involved in the storage and transmission of genetic information. They are also involved in the regulation of gene expression.

The correct answer is: D. All of the above.

Economic liberalism started in India in the early 1990s, with the introduction of a series of economic reforms. These reforms included substantial changes in the licensing policy, removal of procedural hurdles for foreign direct investment, and significant reductions in the import tax rates.

The licensing policy was a system that required businesses to obtain a license from the government before they could start or expand operations. This system was very restrictive and made it difficult for businesses to operate. The reforms abolished the licensing policy, which made it easier for businesses to start and expand operations.

The reforms also removed procedural hurdles for foreign direct investment. This made it easier for foreign companies to invest in India. The reforms also significantly reduced the import tax rates. This made it cheaper for businesses to import goods and services.

The economic reforms of the early 1990s had a significant impact on the Indian economy. They led to increased economic growth, higher levels of foreign investment, and a more open and competitive economy.

Here are some additional details about each of the options:

• Option A: Substantial changes in the licensing policy.

A fixture is a device that holds and locates a workpiece during an inspection or for a manufacturing operation. It can also be used to check the accuracy of a workpiece. Fixtures are typically made of metal, but can also be made of plastic or wood. They are designed to hold the workpiece in a specific position so that it can be machined or inspected accurately.

There are many different types of fixtures, each designed for a specific purpose. Some common types of fixtures include:

• Vises: Vises are used to hold workpieces in place while they are being machined.
• Jigs: Jigs are used to guide cutting tools during machining operations.
• Fixture plates: Fixture plates are used to hold workpieces in place while they are being inspected.
• Clamping fixtures: Clamping fixtures are used to hold workpieces in place while they are being machined or inspected.

Fixtures are an essential part of many manufacturing processes. They help to ensure that workpieces are held in the correct position and that they are machined or inspected accurately. This helps to improve the quality of manufactured products and to reduce the cost of manufacturing.

The correct answer is: B. Potential energy

Potential energy is energy that is stored in an object due to its position or state. In the case of a watch spring, the potential energy is stored in the coils of the spring. When the spring is wound, the coils are compressed, and this compression stores energy. When the spring is released, the energy is converted into kinetic energy, which powers the watch.

Kinetic energy is energy that is due to an object's motion. An object with kinetic energy can do work, such as moving another object or causing damage.

Heat energy is energy that is due to the motion of atoms and molecules. Heat energy can be transferred from one object to another by conduction, convection, or radiation.

Chemical energy is energy that is stored in the bonds between atoms. Chemical energy can be released when these bonds are broken, such as in a chemical reaction.

The Asian-Pacific Trade Agreement (APTA) is a free trade agreement between 16 countries in the Asia-Pacific region. It was established in 1975 and is the oldest regional trade agreement in the Asia-Pacific region. The agreement aims to promote trade and investment between the member countries by reducing tariffs and other trade barriers.

The member countries of APTA are:

• Bangladesh
• Bhutan
• Brunei
• Cambodia
• China
• India
• Indonesia
• Japan
• Laos
• Malaysia
• Myanmar
• Nepal
• Pakistan
• Singapore
• Sri Lanka
• Thailand

India is not a member of APTA because it has not ratified the agreement. India has been a signatory to the agreement since 1997, but it has not yet ratified the agreement. The main reason for India's non-ratification of the agreement is that India wants to protect its domestic industries from competition from other countries in the region.

India is a large and growing economy, and it has a large domestic market. Indian companies are concerned that if they are exposed to competition from other countries in the region, they will not be able to compete and will lose market share. This is why India has not yet ratified the APTA agreement.

However, India is in the process of negotiating a free trade agreement with China. If this agreement is successful, it could lead to India ratifying the APTA agreement. This is because India would be able to protect its domestic industries from competition from China by negotiating special provisions in the free trade agreement.

Overall, India is not a member of APTA because it has not ratified the agreement. The main reason for India's non-ratification of the agreement is that India wants to protect its domestic industries from competition from other countries in the region. However, India is in the process of negotiating a free trade agreement with China, and if this agreement is successful, it could lead to India ratifying the APTA agreement.

The correct answer is D. All of the above are major challenges to fiscal management in West Bengal.

A high revenue deficit means that the state government is spending more money than it is taking in through taxes and other revenue sources. This can lead to a number of problems, including a decline in the state's credit rating, which makes it more difficult to borrow money. It can also lead to inflation, as the government is forced to print more money to cover its expenses.

Growing public debt is another major challenge to fiscal management in West Bengal. The state's debt has been increasing steadily in recent years, and it is now one of the highest in the country. This means that the state government is paying a lot of interest on its debt, which takes away money that could be used for other purposes, such as education and healthcare.

Increasing expenditure on subsidies is also a major challenge to fiscal management in West Bengal. The state government spends a lot of money on subsidies, such as food subsidies and fuel subsidies. These subsidies can be helpful to low-income households, but they can also put a strain on the state's budget.

All of these challenges make it difficult for the state government of West Bengal to manage its finances effectively. This can have a number of negative consequences, such as a decline in the quality of public services, an increase in taxes, and a decrease in investment.

The correct answer is D. All of the above.

Opportunity cost is the cost of an alternative that must be forgone in order to pursue a certain action. For example, if you choose to go to work, you are forgoing the opportunity to relax at home. Time reference is the idea that the value of something depends on when it is received. For example, $100 today is worth more than $100 in a year because you can invest the $100 today and earn interest on it. Equimarginal is the idea that you should allocate your resources in such a way that the marginal benefit of each resource is equal. For example, if you are trying to decide how much to spend on advertising, you should spend money on advertising until the marginal benefit of advertising is equal to the marginal cost of advertising.

Opportunity cost is a fundamental concept in economics. It is the cost of any activity that is given up in order to pursue another activity. Opportunity cost is often used to compare the costs and benefits of different choices. For example, if you are trying to decide whether to go to college or get a job, you need to consider the opportunity cost of each option. The opportunity cost of going to college is the income you could have earned if you had gotten a job instead. The opportunity cost of getting a job is the education you could have received if you had gone to college instead.

Time reference is another important concept in economics. It is the idea that the value of something depends on when it is received. For example, $100 today is worth more than $100 in a year because you can invest the $100 today and earn interest on it. This is because money has time value. The time value of money is the idea that money is worth more today than it will be in the future because you can earn interest on it.

Equimarginal is a concept in economics that states that you should allocate your resources in such a way that the marginal benefit of each resource is equal. For example, if you are trying to decide how much to spend on advertising, you should spend money on advertising until the marginal benefit of advertising is equal to the marginal cost of advertising. This is because you should not spend more money on advertising than you are getting in return.

The correct answer is: A. 1922

The first Central Legislative Assembly was constituted on 9 January 1922. It was a bicameral legislature, consisting of a Council of State and a House of Assembly. The Council of State had 60 members, of whom 30 were elected and 30 were nominated by the Governor-General. The House of Assembly had 140 members, of whom 100 were elected and 40 were nominated by the Governor-General.

Option B: 1923 is incorrect. The first Central Legislative Assembly was constituted in 1922, not 1923.

Option C: 1921 is incorrect. The first Central Legislative Assembly was constituted in 1922, not 1921.

Option D: 1920 is incorrect. The first Central Legislative Assembly was constituted in 1922, not 1920.

The correct answer is: The southwest monsoon.

The southwest monsoon is a seasonal wind that blows from the southwest towards the northeast across the Indian subcontinent during the summer months. It is caused by the difference in temperature between the land and the ocean. The land heats up faster than the ocean, causing the air above the land to rise. This creates an area of low pressure over the land. The air from the ocean, which is cooler and at a higher pressure, flows in to fill this low pressure area. This flow of air is the southwest monsoon.

The southwest monsoon brings significant rainfall to West Bengal. The state receives an average of 1,200 mm of rainfall during the monsoon season. This rainfall is essential for the agriculture and economy of the state.

The other options are incorrect because they are not monsoon winds. Trade winds are winds that blow from the northeast towards the southwest in the tropics. Westerlies are winds that blow from the west towards the east in the mid-latitudes. Southerlies are winds that blow from the south towards the north in the Southern Hemisphere. Nor'westers are winds that blow from the northwest towards the southeast in India.

The correct answer is: D. President in consultation with Chief Justice of India

The President can remove a judge of the High Court only on the recommendation of the Chief Justice of India. The President can also remove a judge of the Supreme Court only on the recommendation of the Chief Justice of India and the majority of the judges of the Supreme Court.

The President is the head of the executive branch of the government and is responsible for appointing and removing judges of the High Court and the Supreme Court. The Chief Justice of India is the head of the judiciary and is responsible for the administration of justice in the country.

The President and the Chief Justice of India are the two most important figures in the Indian judicial system. The President is responsible for ensuring that the judiciary is independent and impartial, while the Chief Justice of India is responsible for ensuring that the judiciary is efficient and effective.

The President and the Chief Justice of India work together to ensure that the Indian judicial system is fair and just for all citizens.

The biosphere is the part of Earth where life exists. It includes the land, water, and air, as well as the organisms that live in these areas. The biosphere is a thin layer that surrounds the Earth, and it is constantly changing.

The thickness of the biosphere varies depending on the definition used. Some scientists define the biosphere as the part of Earth where life can exist, while others define it as the part of Earth where life does exist. The thickness of the biosphere is also affected by the presence of water. Water is essential for life, and it is found in the atmosphere, on the land, and in the oceans. The thickness of the biosphere is therefore greater in areas where there is more water.

The biosphere is a dynamic system that is constantly changing. The Earth's climate is changing, and this is affecting the biosphere. The biosphere is also affected by human activities, such as pollution and deforestation. These activities are causing the biosphere to shrink, and they are also causing the biosphere to become more polluted.

The biosphere is a vital part of Earth, and it is important to protect it. We need to reduce pollution and deforestation, and we need to find ways to adapt to climate change. We also need to learn more about the biosphere, so that we can better understand how it works and how we can protect it.

The other options are incorrect because they do not accurately reflect the thickness of the biosphere. Option A is too high, and option B is too low. Option D is also too high, and it is not supported by scientific evidence.

The correct answer is: C. Phototactic.

Phototaxis is the movement of an organism in response to a light stimulus. It is a type of taxis, a general term for movement in response to a stimulus. Phototaxis can be positive, meaning that the organism moves towards the light, or negative, meaning that the organism moves away from the light.

In insects, phototaxis is often used to find food or mates. Some insects, such as moths, are attracted to light at night. This is because they use the moon to navigate, and they can become confused by artificial light sources. Other insects, such as fireflies, use light to attract mates.

Phototaxis can also be used to avoid predators. Some insects, such as grasshoppers, will jump away from light. This is because they are sensitive to ultraviolet light, which is emitted by many predators.

Phototaxis is a complex behavior that is controlled by a number of different genes. It is an important survival mechanism for many insects, and it plays a role in a variety of other behaviors, such as reproduction and migration.

A. Phototropism is the growth of a plant part in response to a light stimulus. It is a type of tropism, a general term for growth in response to a stimulus.

The 14 Points were a response to the failure of the Nehru Report, which had been drafted by the Indian National Congress and proposed a system of government for India that would have given Hindus a majority of seats in the central legislature.

The 14 Points demanded that Muslims be given a separate electorate, that they be guaranteed representation in all government bodies, that they be allowed to establish their own educational institutions, and that they be given control over their own religious affairs. The 14 Points also demanded that Muslims be given a greater share of government jobs and that they be allowed to form their own provinces.

The 14 Points were rejected by the Indian National Congress, and they led to a growing rift between the Hindus and Muslims in India. The 14 Points were one of the factors that led to the partition of India in 1947.

The other options are incorrect because they are not the years in which the 14 Points were presented.

The correct answer is B. $frac{1}{{{text{y}} - {text{x}}}}$.

A probability density function (PDF) is a function that describes the probability of a continuous random variable taking on a certain value. The PDF of a uniform distribution is a constant function over the interval of interest, and zero elsewhere. In this case, the interval of interest is $[x, y]$, so the PDF is $frac{1}{{{text{y}} - {text{x}}}}$.

Option A, $y - x$, is not a probability density function because it is not non-negative and does not integrate to 1. Option C, $x - y$, is also not a probability density function because it is not non-negative. Option D, $frac{1}{{{text{x}} - {text{y}}}}$, is not a probability density function because it is not defined for $x > y$.

The correct answer is (b).

CRR stands for Cash Reserve Ratio. It is the percentage of the total deposits that banks are required to keep with the Reserve Bank of India (RBI). When the RBI increases the CRR, banks have to keep more money with the RBI and less money available to lend to customers. This reduces the amount of money in circulation in the economy, which is known as liquidity.

A reduction in liquidity can have a number of effects on the economy. It can make it more difficult for businesses to get loans, which can lead to slower economic growth. It can also lead to higher interest rates, as banks will need to charge more to compensate for the fact that they have less money to lend.

However, a reduction in liquidity can also be used to control inflation. When there is too much money in circulation, prices tend to rise. By reducing liquidity, the RBI can help to bring down inflation.

In conclusion, an increase in CRR by the Reserve Bank of India results in a reduction in liquidity in the economy. This can have a number of effects on the economy, including slower economic growth, higher interest rates, and lower inflation.

The correct answer is A. Fundamental right.

A fundamental right is a right that is considered to be essential to a person's freedom and dignity. It is a right that is protected by the law and cannot be taken away by the government.

The right to property is a fundamental right in India. It is guaranteed by Article 300A of the Constitution. This article states that no person shall be deprived of his property except by due process of law.

The right to property is important because it allows people to own and control their own property. This includes land, houses, cars, and other assets. The right to property also allows people to earn a living and to provide for their families.

The right to property is not absolute. It can be limited by the government in certain circumstances. For example, the government can take away property for public purposes, such as building a road or a school. However, the government must pay compensation for any property that it takes away.

The right to property is a fundamental right that is important for the freedom and dignity of individuals. It is a right that is protected by the law and cannot be taken away by the government without due process of law.

The other options are incorrect because:

• A natural right is a right that is believed to be inherent in all people, regardless of their nationality, race, or religion.
• A legal right is a right that is created by law.
• A moral right is a right that is based on what is considered to be right and wrong.

In addition, remittances can also help to reduce poverty, improve gender equality, and promote social cohesion.

The correct answer is: A perfectly competitive firm should reduce output or shut down in the short run if market price is equal to marginal cost, and the price is less than average variable cost.

A perfectly competitive firm is a price taker, which means that it cannot influence the market price of its product. The firm's marginal cost curve intersects its average variable cost curve at the minimum point of the average variable cost curve. If the market price is equal to or greater than the average variable cost, the firm will produce at the point where marginal cost equals price. However, if the market price is less than the average variable cost, the firm will not produce any output, because it will lose money on every unit produced.

Here is a diagram that illustrates the concept:

[Diagram of a perfectly competitive firm's cost curves]

The firm's marginal cost curve is MC, its average total cost curve is ATC, and its average variable cost curve is AVC. The market price is P. If the market price is equal to or greater than the average variable cost, the firm will produce at the point where marginal cost equals price. However, if the market price is less than the average variable cost, the firm will not produce any output, because it will lose money on every unit produced.

In conclusion, a perfectly competitive firm should reduce output or shut down in the short run if market price is equal to marginal cost, and the price is less than average variable cost.

The correct answer is (a) 1580.

The correct answer is A. Spleen.

The spleen is an organ in the human body that is located in the upper left abdomen. It is part of the lymphatic system, which helps to fight infection. The spleen also helps to remove old red blood cells from the blood.

The pituitary gland is a small, pea-sized gland located at the base of the brain. It is often called the "master gland" because it produces hormones that control many other glands in the body.

The thyroid gland is a butterfly-shaped gland located in the neck. It produces hormones that regulate metabolism, growth, and development.

The adrenal glands are two small glands located on top of the kidneys. They produce hormones that help to regulate the body's response to stress, as well as hormones that regulate blood sugar levels.

The spleen is not an endocrine gland because it does not produce hormones.

The correct answer is C. Ship.

A knot is a unit of speed equal to one nautical mile per hour. It is commonly used to measure the speed of ships and boats. One nautical mile is equal to 1.852 kilometers or 1.150778 miles.

Option D is incorrect because sound waves are not measured in knots. They are typically measured in meters per second or kilometers per second.

The correct answer is A. Lamarck.

Jean-Baptiste Lamarck was a French naturalist who proposed the theory of use and disuse to explain evolution. He believed that organisms could pass on acquired characteristics to their offspring. For example, he thought that giraffes developed long necks because they stretched their necks to reach leaves on tall trees.

Charles Darwin was a British naturalist who proposed the theory of natural selection to explain evolution. He believed that organisms that are better adapted to their environment are more likely to survive and reproduce. This leads to the gradual evolution of species.

Hugo de Vries was a Dutch botanist who proposed the theory of mutation to explain evolution. He believed that evolution occurs in large jumps, or mutations, rather than gradually.

Alfred Russel Wallace was a British naturalist who independently developed the theory of natural selection. He was a contemporary of Darwin and they corresponded extensively.

The theory of use and disuse is no longer accepted by the scientific community. However, it was an important step in the development of our understanding of evolution.

The correct answer is (d), Delhi.

The South-West Monsoon is a seasonal wind pattern that brings heavy rains to India and other parts of South Asia. The monsoon season typically runs from June to September, and the amount of rainfall varies from place to place.

Kolkata, Mangalore, and Chennai are all located on the coast of India, and they receive a significant amount of rainfall during the monsoon season. Delhi, on the other hand, is located in the northern part of India, and it receives much less rainfall during the monsoon season.

In fact, Delhi is one of the driest cities in India. The average annual rainfall in Delhi is only about 700 mm, while the average annual rainfall in Kolkata is about 1,500 mm, the average annual rainfall in Mangalore is about 3,000 mm, and the average annual rainfall in Chennai is about 1,200 mm.

The reason why Delhi receives less rainfall than other parts of India is because it is located in a rain shadow. A rain shadow is an area that receives less rainfall than the surrounding areas because of the presence of mountains. In the case of Delhi, the Himalayas block the moisture-laden winds from the Bay of Bengal, which results in less rainfall in Delhi.

The correct answer is C) Susunia Hill.

Susunia Hill is a Paleolithic site located in the Bankura district of West Bengal, India. It is one of the oldest and most important Paleolithic sites in the country. The site has yielded a rich collection of stone tools, including hand axes, cleavers, and scrapers. These tools have been dated to the Lower Paleolithic period, which is between 2.5 million and 1 million years ago.

The discovery of Susunia Hill was made in 1926 by a team of archaeologists led by N. K. Bose. The team found a large number of stone tools at the site. These tools were made from a variety of materials, including quartz, chert, and chalcedony. The tools were found in association with animal fossils, including those of elephants, rhinoceroses, and hippopotamuses.

The discovery of Susunia Hill has provided valuable insights into the early history of human occupation in India. The site shows that humans were living in the region at least 2.5 million years ago. The tools found at the site provide evidence of the early development of human technology.

The other options are incorrect because they are not Paleolithic sites. Birbhanpur is a Buddhist site, Pandu Rajar Dhibi is an Iron Age site, and Mahasthangarh is a medieval city.

The correct answer is C. Spinal cord.

The spinal cord is a long, thin, tubular bundle of nervous tissue that extends from the brain down the back through the spinal canal. It is made up of millions of nerve fibers that carry messages between the brain and the rest of the body.

The spinal cord is responsible for controlling many of the body's automatic functions, such as breathing, heart rate, and digestion. It also plays a role in movement, sensation, and reflexes.

Reflexes are involuntary actions that occur in response to a stimulus. For example, when you touch a hot stove, your hand will jerk away automatically. This reflex is controlled by the spinal cord, without any input from the brain.

The spinal cord is also responsible for transmitting messages from the brain to the muscles. These messages control voluntary movements, such as walking, talking, and eating.

The spinal cord is a vital part of the nervous system. It is responsible for controlling many of the body's automatic functions, as well as movement, sensation, and reflexes.

The correct answer is A. Rises.

Income elasticity of demand is a measure of how responsive the demand for a good or service is to changes in consumer income. It is calculated as the percentage change in the quantity demanded divided by the percentage change in income.

A positive income elasticity of demand means that the demand for a good or service increases as income increases. This is because as people have more money, they are able to afford to buy more of the good or service.

A negative income elasticity of demand means that the demand for a good or service decreases as income increases. This is because as people have more money, they are able to afford to buy more of other goods and services, and so they buy less of the good or service in question.

An income elasticity of demand of zero means that the demand for a good or service does not change as income changes. This is because the good or service is considered to be a necessity, and so people will buy the same amount of it regardless of their income.

In conclusion, the correct answer is A. Rises.

The correct answer is D.

Robbins' definition of economics is "the science of human behavior as a relationship between ends and scarce means which have alternative uses." This means that economics is the study of how people make choices when they have limited resources.

Option A is incorrect because it is a definition of economics given by Adam Smith.

Option B is incorrect because it is too broad. Economics is not just the study of the ordinary business of human life. It is also the study of how people make choices when they have limited resources.

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

The answer is D. Cow : Shed.

A garage is a building or structure where vehicles are kept, a sty is a pen or enclosure for pigs, and a stable is a building or enclosure for horses. A shed is a small building or shelter, typically used for storage or as a workshop.

While a shed can be used to house a cow, it is not the most common or traditional type of housing for cows. Cows are typically housed in barns, which are larger and more well-suited to their needs. Sheds are more commonly used for housing smaller animals, such as chickens or rabbits.

Therefore, the odd word in the list is "shed".

The correct answer is D. No error.

The sentence "The warden forbade the student from leaving the hostel" is grammatically correct. The word "forbade" is a verb that means "to order someone not to do something." The word "student" is a noun that refers to a person who is enrolled in a school. The word "from" is a preposition that indicates that the student is not allowed to leave the hostel. The word "leaving" is a verb that means "to go away from a place." The word "hostel" is a noun that refers to a building where students live.

The sentence is grammatically correct because it follows the rules of English grammar. The word order is correct, and the verbs agree with the subjects. The sentence also makes sense, and it is clear what the writer is trying to say.

The other options are incorrect because they contain grammatical errors. Option A is incorrect because the word "the" is not necessary before the word "warden." Option B is incorrect because the word "forbade" is not a verb. Option C is incorrect because the word "from" is not a preposition.

The correct answer is: C. Mean of f(x) and g(x) are different; Variance of f(x) and g(x) are same.

The mean of a probability density function is given by:

$$mu = int_{-infty}^{infty} x f(x) dx$$

The variance of a probability density function is given by:

$$sigma^2 = int_{-infty}^{infty} (x - mu)^2 f(x) dx$$

For $f(x)$ and $g(x)$ as given in the question, we have:

$$mu_f = int_{-a}^0 x frac{x}{a} + 1 dx = frac{a^2}{4} + 0 = frac{a^2}{4}$$

$$mu_g = int_{-a}^0 x frac{-x}{a} + 1 dx = -frac{a^2}{4} + 0 = -frac{a^2}{4}$$

Therefore, $mu_f neq mu_g$.

The variance of $f(x)$ is given by:

$$sigma^2_f = int_{-a}^0 (x - mu_f)^2 frac{x}{a} + 1 dx = frac{a^4}{16} + 0 = frac{a^4}{16}$$

The variance of $g(x)$ is given by:

$$sigma^2_g = int_{-a}^0 (x - mu_g)^2 frac{-x}{a} + 1 dx = frac{a^4}{16} + 0 = frac{a^4}{16}$$

Therefore, $sigma^2_f = sigma^2_g$.

Therefore, the mean of $f(x)$ and $g(x)$ are different, but the variance of $f(x)$ and $g(x)$ are the same.

The correct answer is: C. Same as the weight of the man.

When a man stands in a lift which accelerates upwards, the man experiences two forces: the force of gravity pulling him down, and the reaction force of the floor of the lift pushing him up. The reaction force of the floor of the lift is equal in magnitude but opposite in direction to the force of gravity, so the net force on the man is zero. This means that the man does not accelerate, and his weight remains the same.

Option A is incorrect because the reaction force of the floor of the lift cannot be greater than the force of gravity. The force of gravity is a fundamental force of nature, and it is impossible for any other force to be greater than it.

Option B is incorrect because the reaction force of the floor of the lift cannot be less than the force of gravity. The man is standing on the floor of the lift, and the floor of the lift is supporting his weight. If the reaction force of the floor of the lift were less than the force of gravity, the man would fall through the floor.

Option D is incorrect because the reaction force of the floor of the lift cannot be zero. The man is standing on the floor of the lift, and the floor of the lift is supporting his weight. If the reaction force of the floor of the lift were zero, the man would float in the air.

The correct answer is B. Work and Power.

Work is the product of force and distance, while power is the rate at which work is done. Both work and power have the dimensions of force times distance, or $ML^2T^{-2}$.

Force is the product of mass and acceleration, while momentum is the product of mass and velocity. Both force and momentum have the dimensions of mass times acceleration, or $MLT^{-2}$.

Energy is the ability to do work, while momentum is the product of mass and velocity. Both energy and momentum have the dimensions of mass times length squared times time squared, or $ML^2T^{-2}$.

Therefore, the only pair of physical quantities that have the same dimensions is work and power.

Hydrogen fuel is a renewable resource of energy because it can be produced from water, which is a renewable resource. Wind energy is a renewable resource of energy because it comes from the wind, which is a natural force. Solar energy is a renewable resource of energy because it comes from the sun, which is a natural source of energy.

Here are some additional details about each option:

• Hydrogen fuel is a renewable resource of energy because it can be produced from water, which is a renewable resource. Water is a naturally occurring substance that is constantly being recycled through the Earth's water cycle. This means that there is a virtually unlimited supply of water available for the production of hydrogen fuel.
• Wind energy is a renewable resource of energy because it comes from the wind, which is a natural force. The wind is caused by the uneven heating of the Earth's surface by the sun. This uneven heating creates differences in air pressure, which in turn causes the wind to blow. The wind is a constantly changing force, which means that wind energy is a variable source of energy. However, the wind is a renewable resource, and it can be harnessed to generate electricity.
• Solar energy is a renewable resource of energy because it comes from the sun, which is a natural source of energy. The sun is a star that emits a vast amount of energy in the form of light and heat. This energy can be harnessed to generate electricity, heat water, or power other devices. Solar energy is a clean and sustainable source of energy, and it is becoming increasingly popular as the cost of solar panels decreases.

The correct answer is: (A) and (R) both are true.

In the long run, all firms in a perfectly competitive market will earn only normal profit. This is because firms will enter the market if there are profits to be made, and will exit the market if there are losses to be made. As firms enter the market, the supply of the good will increase, which will drive down the price of the good. As the price of the good decreases, firms will experience a decrease in marginal revenue, which will cause them to decrease output. This process will continue until all firms are earning only normal profit.

In the long run, all firms in a perfectly competitive market will incur minimum average cost. This is because firms will have had time to adjust their plant size to the level that minimizes average cost. In addition, firms will not incur any selling costs, as there is no product differentiation in a perfectly competitive market.

Therefore, both assertion (A) and reason (R) are true.

It extends from the Earth's surface to about 12 kilometers (7.5 miles) above sea level. The temperature of the troposphere decreases with altitude. This is because the air in the troposphere is heated by the Earth's surface. The stratosphere is the second layer of Earth's atmosphere. It extends from about 12 to 50 kilometers (7.5 to 31 miles) above sea level. The temperature of the stratosphere increases with altitude. This is because the ozone layer in the stratosphere absorbs ultraviolet radiation from the Sun. The exosphere is the outermost layer of Earth's atmosphere. It extends from about 500 to 10,000 kilometers (310 to 6,200 miles) above sea level. The temperature of the exosphere decreases with altitude. This is because the air in the exosphere is very thin and there is not enough matter to absorb heat from the Sun.

There are a number of factors that contribute to the low sex-ratio in Haryana. One factor is the practice of female foeticide, which is the selective abortion of female fetuses. This is often done due to a preference for sons, who are seen as being more valuable than daughters. Another factor is the high rate of female infant mortality, which is the death of a girl child before her first birthday. This is often due to neglect or malnutrition.

The low sex-ratio in Haryana has a number of negative consequences. It can lead to a shortage of women in the workforce, which can impact the economy. It can also lead to social problems, such as an increase in crime and violence.

The government of Haryana has taken a number of measures to address the issue of the low sex-ratio. These measures include awareness campaigns, stricter laws against female foeticide, and programs to improve the health and well-being of girls and women.

Despite these measures, the problem of the low sex-ratio in Haryana remains a serious one. It is important to continue to raise awareness of the issue and to take steps to address it.

The correct answer is: C. ream : paper

A skein is a length of yarn wound on a reel or in a ball. A ream is a quantity of paper consisting of 500 sheets. Both a skein and a ream are units of measurement for a raw material that is used to create a finished product. In the case of a skein, the finished product is yarn. In the case of a ream, the finished product is paper.

The other options do not have a similar relationship. A squeeze is not a unit of measurement for a lemon. Fire is not a raw material that is used to create coal. A tree is not a unit of measurement for lumber. A plow is not a raw material that is used to create an acre.

The correct answer is (c), Sarath (BMP-II).

The correct answer is: B. It uses Deuterium, a heavier isotope of hydrogen, rather than Protium.

Heavy water is water that contains a higher than normal proportion of the heavy isotope of hydrogen, deuterium. It is also called deuterium oxide. The chemical formula of heavy water is $D_2O$, while the chemical formula of normal water is $H_2O$.

Heavy water is denser than normal water because the deuterium atom is heavier than the hydrogen atom. The density of heavy water is 1.107 grams per cubic centimeter, while the density of normal water is 0.997 grams per cubic centimeter.

Heavy water is not used by heavy industries such as steel, chemicals, etc. It is used in nuclear reactors as a moderator and coolant. It is also used in research and medical applications.

Here is a brief explanation of each option:

• Option A: Heavy water is not three times denser than normal water. The density of heavy water is 1.107 grams per cubic centimeter, while the density of normal water is 0.997 grams per cubic centimeter.
• Option B: Heavy water uses deuterium, a heavier isotope of hydrogen, rather than protium. This is the correct answer.
• Option C: Heavy water is not used by heavy industries such as steel, chemicals, etc. It is used in nuclear reactors as a moderator and coolant. It is also used in research and medical applications.
• Option D: Heavy water is used in nuclear reactors as a moderator and coolant. It is also used in research and medical applications. This is not the correct answer because it does not explain why heavy water is called heavy water.

The correct answer is (c) U.S.A.

The federal system of India was inspired by the Constitution of the United States of America. The Indian Constitution was adopted on 26 November 1949 and came into effect on 26 January 1950. It is the longest written constitution of any country in the world.

The Indian Constitution is based on the principle of federalism, which means that power is shared between the central government and the state governments. The central government has power over matters such as defense, foreign affairs, and currency. The state governments have power over matters such as education, health, and agriculture.

The Indian Constitution also provides for a system of checks and balances between the central government and the state governments. This means that no one branch of government can become too powerful.

The federal system of India has been successful in promoting unity and diversity in the country. It has also helped to protect the rights of the people.

The other options are incorrect because:

(a) Canada is a federal state, but its constitution was not the main inspiration for the Indian Constitution.
(b) The United Kingdom is a unitary state, which means that power is concentrated in the central government.
(c) Ireland is a unitary state.

The correct answer is: A) Rural to urban migration.

Rural to urban migration is a major trend observed in West Bengal. This is due to a number of factors, including the following:

* The state's economy is growing rapidly, and there are more job opportunities in urban areas.
* Urban areas offer better infrastructure and amenities than rural areas.
* Many people are moving to urban areas in search of a better quality of life.

Rural to urban migration can have a number of positive and negative effects on the state. On the positive side, it can lead to economic growth and development. It can also lead to the spread of new ideas and technologies. However, rural to urban migration can also lead to overcrowding, pollution, and social problems.

The state government is taking a number of steps to address the challenges of rural to urban migration. These include the following:

* Investing in rural infrastructure and amenities.
* Creating more job opportunities in rural areas.
* Promoting education and awareness about the benefits of living in rural areas.

It is important to manage rural to urban migration in a way that benefits both the state and the migrants. The state government needs to ensure that there are adequate job opportunities and infrastructure in urban areas. It also needs to provide support to migrants who are struggling to adjust to life in urban areas.

The correct answer is (c).

The two trains travel in opposite directions, so they will cross each other when they are at the same point on the track. The first train travels for 1 hour, and the second train travels for 30 minutes. Therefore, the two trains will cross each other at 5:45 P.M.

Option (a) is incorrect because the first train only travels for 1 hour, so it cannot reach place B at 6:30 P.M.

Option (b) is incorrect because the first train only travels for 1 hour, so it cannot reach place B at 5:48 P.M.

Option (d) is incorrect because the first train only travels for 1 hour, so it cannot reach place B at 5:36 P.M.

The correct answer is: for.

The baby is crying for help because they need something. It could be that they are hungry, tired, or need a diaper change. The baby is crying because they are not able to communicate their needs to the adult in the room, so they are using crying as a way to get attention.

The other options are not correct because they do not make sense in the context of the sentence. The baby is not crying of help, because they are not crying because of help. They are crying to get help, but they are not crying to help. They are not crying since help, because they are not crying because help has been given.

The correct answer is: All of the above.

Perfect price discrimination is a theoretical concept in which a monopolist can charge each consumer the maximum price they are willing to pay for a good or service. This is also known as first-degree price discrimination.

Second degree price discrimination occurs when a monopolist charges different prices for different units of a good or service, but all consumers pay the same price for each unit. This is also known as block pricing.

Third degree price discrimination occurs when a monopolist charges different prices to different groups of consumers, based on their willingness to pay. This is also known as market segmentation.

All three types of price discrimination can be considered optimal pricing, as they allow the monopolist to extract more surplus from consumers. However, perfect price discrimination is the most efficient form of price discrimination, as it results in the highest level of consumer surplus.

Here is a more detailed explanation of each type of price discrimination:

• Perfect price discrimination is a theoretical concept in which a monopolist can charge each consumer the maximum price they are willing to pay for a good or service. This is also known as first-degree price discrimination. Perfect price discrimination is the most efficient form of price discrimination, as it results in the highest level of consumer surplus. However, it is also the most difficult to achieve, as it requires the monopolist to have perfect information about each consumer's willingness to pay.
• Second degree price discrimination occurs when a monopolist charges different prices for different units of a good or service, but all consumers pay the same price for each unit. This is also known as block pricing. Second degree price discrimination is less efficient than perfect price discrimination, as it results in a lower level of consumer surplus. However, it is easier to achieve than perfect price discrimination, as it does not require the monopolist to have perfect information about each consumer's willingness to pay.
• Third degree price discrimination occurs when a monopolist charges different prices to different groups of consumers, based on their willingness to pay. This is also known as market segmentation. Third degree price discrimination is less efficient than perfect price discrimination, but it is more efficient than second degree price discrimination. It is also easier to achieve than perfect price discrimination or second degree price discrimination, as it does not require the monopolist to have perfect information about each consumer's willingness to pay.

The correct answer is A. Fungus.

Yeast is a single-celled fungus that is used in baking to make bread rise. It is a living organism that converts sugar into carbon dioxide and alcohol. The carbon dioxide bubbles cause the dough to rise, and the alcohol evaporates during baking.

Bacteria are also single-celled organisms, but they are not fungi. Bacteria are much smaller than yeast cells, and they do not have a nucleus. Bacteria can cause diseases, but they can also be used to make yogurt, cheese, and other fermented foods.

Seeds are the reproductive units of plants. They contain an embryo plant and a food supply that the embryo uses to grow. Seeds are usually enclosed in a protective coat.

Plants are multicellular organisms that are photosynthetic. They make their own food using sunlight, water, and carbon dioxide. Plants have roots, stems, leaves, and flowers.

In conclusion, yeast is a fungus that is used in baking to make bread rise. It is a living organism that converts sugar into carbon dioxide and alcohol. The carbon dioxide bubbles cause the dough to rise, and the alcohol evaporates during baking.

The correct answer is (a), only one of the statements is correct.

The Jhelum River passes through the Wular Lake. The Krishna River does not directly feed the Kolleru Lake, but it does feed the Nagarjuna Sagar Dam, which in turn feeds the Kolleru Lake. The meandering of the Gandak River did not form the Kanwar Lake, but it did form the Triveni Sangam, which is a confluence of the Ganges, Yamuna, and Saraswati rivers.

Here is a more detailed explanation of each statement:

• The Jhelum River is a major river in the Indian subcontinent. It originates in the Himalayas and flows through the Indian state of Jammu and Kashmir before entering Pakistan. The river passes through the Wular Lake, which is the largest freshwater lake in Jammu and Kashmir.
• The Krishna River is a major river in India. It originates in the Western Ghats and flows through the states of Maharashtra, Karnataka, Andhra Pradesh, and Telangana.

The Kolleru Lake is a large freshwater lake located in the state of Andhra Pradesh.
• The Gandak River is a major river in the Indian subcontinent. It originates in the Himalayas and flows through the Indian states of Uttarakhand, Uttar Pradesh, Bihar, and Jharkhand before entering Nepal. The meandering of the Gandak River did not form the Kanwar Lake, but it did form the Triveni Sangam, which is a confluence of the Ganges, Yamuna, and Saraswati rivers. The Kanwar Lake is a small freshwater lake located in the state of Uttar Pradesh.

The correct answer is A. Water : Boat.

A train travels on a track, just as a boat travels on water. A bullet travels through a barrel, but it is not necessary for the bullet to have a barrel in order to travel. An idea does not need a brain in order to exist, and fame does not need television in order to exist.

In addition, trains and boats are both vehicles that are used for transportation. Bullets and barrels are both tools that are used for shooting. Ideas and brains are both things that are used for thinking. Fame and television are both things that are used for recognition.

Therefore, the answer that best completes the analogy "Train : Track" is "Water : Boat."
