Which one of the following is a filter feeder?
1. ACatfish
2. BOctopus
3. COyster
4. DPelican
Answer and explanation
Correct answer: C
* Filter feeders are a subgroup of suspension-feeding animals that feed by straining suspended matter and food particles from water, typically by passing the water over a specialised filtering structure.
* Some animals that use this method of feeding are clams, krill, sponges, baleen whales, and many fish (including some sharks). Some birds, such as flamingos and certain species of duck, are also filter feeders. Filter feeders can play an important role in clarifying water, and are therefore considered ecosystem engineers. They are also important in bioaccumulation and, as a result, as indicator organisms. * Oyster is one of the filter feeders.
Pearl Farming - Pearls are the only gemstones in the world that come from a living creature. Mollusks such as oysters and mussels produce these precious jewels. - Pearl culture practices are present in Gujarat, Maharashtra, Bihar, Odisha, Kerala, Rajasthan, Jharkhand, Goa, and Tripura.

What is the position of the Right to Property in India?
1. ALegal right available to citizens only
2. BLegal right available to any person
3. CFundamental Right available to citizens only
4. DNeither Fundamental Right nor legal right
Answer and explanation
Correct answer: B
Previously a Fundamental Right - Before 1978, the Indian Constitution guaranteed the right to property as a fundamental right under Article 19(1)(f) and Article 31. - This meant citizens had the right to acquire, hold, and dispose of their property. - Article 31 also ensured that the government couldn't take over private property without due compensation and for public purposes only.
Change in 1978 - The 44th Amendment Act of 1978 changed the status of the Right to Property. - Articles 19(1)(f) and 31 were removed from the list of fundamental rights. - A new Article, 300-A, was introduced under Part XII of the Constitution.
Current Status: A legal right available to any person. - Article 300-A states, "No person shall be deprived of his property save by authority of law." - This means the government can still acquire private property, but only under legal authorization. - The law should be fair and reasonable, and the government has the power to decide the quantum of compensation.

In the context of hereditary diseases, consider the following statements: 1. Passing on mitochondrial diseases from parent to child can be prevented by mitochondrial replacement therapy either before or after in vitro fertilization of egg. 2. A child inherits mitochondrial diseases entirely from mother and not from father. Which of the statements given above is/are correct?
1. A1 only
2. B2 only
3. CBoth 1 and 2
4. DNeither 1 nor 2
Answer and explanation
Correct answer: C
Statement 1 is correct. Mitochondrial replacement therapy (MRT) is a reproductive technique used to prevent the transmission of mitochondrial diseases from mother to child. It involves replacing defective mitochondria in an egg or embryo with healthy mitochondria from a donor. MRT can be performed either before or after in vitro fertilization to ensure that the resulting embryo does not inherit mitochondrial diseases.
Statement 2 is correct. Mitochondrial DNA (mtDNA), which is responsible for encoding genes essential for mitochondrial function, is inherited exclusively from the mother. Therefore, mitochondrial diseases caused by mutations in mtDNA are passed down maternally, and a child cannot inherit mitochondrial diseases from the father.
Therefore, both statements are correct.

Consider the following statements: 1. 'Right to the City' is an agreed human right and the UN-Habitat monitors the commitments made by each country in this regard. 2. 'Right to the City' gives every occupant of the city the right to reclaim public spaces and public participation in the city. 3. 'Right to the City' means that the State cannot deny any public service or facility to the unauthorized colonies in the city. Which of the statements given above is/are correct:
1. A1 only
2. B3 only
3. C1 and 2
4. D2 and 3
Answer and explanation
Correct answer: D
Statement 1 is incorrect. The "Right to the City" is not a formally agreed universal human right in international law. It is a normative and political concept. UN-Habitat uses the idea in the New Urban Agenda, but: it does not legally monitor binding national commitments.
Statement 2 is correct. The Right to the City is the right of all inhabitants (present and future, permanent and temporary) to inhabit, use, occupy, produce, transform, govern, and enjoy cities, towns, and human settlements that are just, inclusive, safe, sustainable and democratic, defined as common goods for enjoying life with dignity and peace. The right to the city further implies responsibilities on governments and people to claim, defend, and promote this right.
Statement 3 is correct. "Right to the City" is interpreted as an inclusive urban citizenship right. The concept says that all city dwellers, including: migrants, slum dwellers, residents of unauthorized colonies, have a claim to urban services and dignity. It views residents not as "encroachers" but as rights-bearing urban citizens who contribute to the city economy. Hence: denial of water, sanitation, waste management, etc. merely because a settlement is "unauthorized" is seen as violating the spirit of Right to the City. Indian courts have also held that basic services cannot be denied even to illegal settlements, as they are part of Article 21 – Right to Life.

2. BArticle 19
3. CArticle 21
4. DArticle 29
Answer and explanation
Correct answer: C
The right to privacy in India is not explicitly mentioned in a single article of the Constitution. However, it is considered an intrinsic part of the fundamental right to life and liberty guaranteed under Article 21.
This recognition came about through a landmark Supreme Court judgment in 2017, K.S. Puttaswamy (Retd) vs Union of India. The court ruled that the right to privacy is an inseparable part of the right to life and personal liberty, and is protected under Article 21.

The vegetation of savannah consists of grassland with scattered small trees, but extensive areas have no trees. The forest development in such areas is generally kept in check by one or more or a combination of some conditions. Which of the following are such conditions? 1. Burrowing animals and termites 2. Fire 3. Grazing herbivores 4. Seasonal rainfall 5. Soil properties Select the correct answer using the codes given below
1. A1 and 2
2. B4 and 5
3. C2, 3 and 4
4. D1, 3 and 5
Answer and explanation
Correct answer: C
The vegetation of savannah consists of grassland with scattered small trees. The forest development in such areas is generally kept in check by one or more or a combination of some conditions. These conditions include fire, grazing herbivores, and seasonal rainfall.
2. Fire is a common occurrence in savannahs and it helps to maintain the grassland by burning out tree saplings.
3. Grazing herbivores also help to maintain the grassland by eating young tree saplings before they can grow into mature trees.
4. Seasonal rainfall also plays a role as it affects the growth of trees and grasses.
1. Burrowing animals and termites, while they do have an impact on the ecosystem, are not the primary factors controlling forest development.
5. Similarly, soil properties can affect the types of vegetation that can grow, but they are not the primary factors controlling forest development in savannahs.
Therefore, the correct answer is (c) 2, 3 and 4.
Savannah Climate: - It is a transitional climate between equatorial rainforests and hot deserts. - It has wet and dry seasons like the monsoon climate but with much less rainfall. Unlike the monsoon climate, it lacks a distinct rainy season. - It has only two seasons—winter and summer, with rain occurring in summer.

Which among the following steps is most likely to be taken at the time of an economic recession?
1. ACut in tax rates accompanied by increase in interest rate.
2. BIncrease in expenditure on public projects.
3. CIncrease in tax rates accompanied by reduction of interest rate.
4. DReduction of expenditure on public projects.
Answer and explanation
Correct answer: B
During an economic recession, the goal is to stimulate economic activity and consumer spending.
A. Cut in Tax Rates & Increase in Interest Rates. Cutting taxes puts more money in people's pockets, potentially increasing spending. However, raising interest rates discourages borrowing and investment, potentially hindering economic growth. This combination could have offsetting effects.
B. Increase in Expenditure on Public Projects. This injects money into the economy through government spending, creating jobs and boosting demand for goods and services. This is a typical measure during recessions.
C. Increase in Tax Rates & Reduction of Interest Rates. Increasing taxes reduces disposable income, dampening consumer spending. Lowering interest rates encourages borrowing and investment, but it might not be effective if there's low confidence in the economy.
D. Reduction of Expenditure on Public Projects. This reduces government spending, taking money out of circulation and potentially worsening the recession.
Therefore, the most likely step during an economic recession is (B) Increase in expenditure on public projects

The term 'ACE2' is talked about in the context of
1. Agenes introduced in the genetically modified plants
2. Bdevelopment of India's own satellite navigation system
3. Cradio collar for wildlife tracking
4. Dspread of viral diseases
Answer and explanation
Correct answer: D
* The term 'ACE2' is talked about in the context of the spread of viral diseases, particularly COVID-19.
* ACE2 stands for Angiotensin-Converting Enzyme 2. It's a protein found on the surface of many cell types in the human body, including those in the lungs, heart, kidneys, and intestines.
* Here's why ACE2 is significant:
* Receptor for SARS-CoV-2: The spike protein on the surface of the SARS-CoV-2 virus, the virus that causes COVID-19, binds to the ACE2 receptor in human cells. This binding is a critical step in the process of how the virus infects cells. * Multiple organ infection: Since ACE2 is expressed in various organs, it provides the virus with multiple potential entry points. This can contribute to the multi-organ complications sometimes associated with COVID-19. * Focus of research: Understanding the interaction between the virus and ACE2 is a major area of research for scientists developing vaccines and treatments for COVID-19.

In the nature, which of the following is/are most likely to be found surviving on a surface without soil? 1. Fern 2. Lichen 3. Moss 4. Mushroom Select the correct answer using the code given below
1. A1 and 4 Only
2. B2 Only
3. C2 and 3
4. D1, 3 and 4
Answer and explanation
Correct answer: C
Fern: * Ferns typically require soil and moisture to grow, as they rely on water-conducting tissues and need a substrate to anchor their roots.
Lichen: * Lichens are a symbiotic association between a fungus and an algae or cyanobacteria. * Lichens are well-adapted to survive on surfaces without soil, such as rocks, tree bark, and even bare ground, as they can obtain their nutrients and moisture directly from the air and precipitation. * Lichens are sensitive to airborne pollutants, such as sulfur dioxide (SO2), nitrogen oxides (NOx), ozone (O3), and heavy metals (like lead and mercury). Sulfur dioxide, for instance, causes chlorosis (yellowing) and necrosis (cell death) in lichen thalli. This sensitivity makes lichens an effective indicator of air quality.
Moss: * Mosses are non-vascular plants that can grow on surfaces without soil, such as rocks, tree trunks, and even roofs. * Mosses have specialised structures that allow them to absorb water and nutrients directly from the environment.
Mushrooms: * Mushrooms are the reproductive structures of fungi, and they typically require a substrate, such as decaying organic matter, to grow. Mushrooms are not able to directly survive on a surface without soil or a nutrient-rich medium.
Therefore, among the given options, lichens and mosses are the most likely to be found surviving on a surface without soil in the natural environment.

Which one of the following effects of creation of black money in India has been the main cause of worry to the Government of India?
1. ADiversion of resources to the purchase of real estate and investment in luxury housing.
2. BInvestment in unproductive activities and purchase of precious stones, jewellery, gold, etc.
3. CLarge donations to political parties and growth of regionalism.
4. DLoss of revenue to the State Exchequer due to tax evasion.
Answer and explanation
Correct answer: D
A. Diversion to Real Estate: While this can happen, it still involves some economic activity and might generate taxes (though potentially not on the full value of the transaction if black money is used).
B. Investment in Unproductive Activities: This can hurt the economy, but the government loses tax revenue regardless of the type of investment if it's funded by black money.
C. Donations to Political Parties: This is a concern, but the lost tax revenue likely outweighs the impact of such donations.
D. Loss of Revenue: Black money, by definition, avoids taxes. This directly reduces the government's income, limiting its ability to fund public services, infrastructure, and social welfare programs.
Tax evasion through black money creation significantly hinders the government's ability to function effectively and meet the needs of its citizens. This is why it's a major concern.

Consider the following statements: 1. In the tropical zone, the western sections of the oceans are warmer than the eastern sections owing to the influence of trade winds. 2. In the temperate zone, westerlies make the eastern sections of oceans warmer than the western sections. Which of the statements given above is/are correct?
1. A1 Only
2. B2 Only
3. CBoth 1 and 2
4. DNeither 1 nor 2
Answer and explanation
Correct answer: C
Statement 1 is correct. The trade winds in the tropical zone blow from east to west, causing the western sections of the oceans to be warmer than the eastern sections. This is because these winds push the warm surface waters towards the west.
Statement 2 is correct. On the other hand, in the temperate zone, the westerlies blow from west to east. These winds push the warm waters towards the eastern sections of the oceans, making them warmer than the western sections.
Therefore, both statements are correct.

With reference to the Indus river system, of the following four rivers, three of them pour into one of them which joins the Indus direct. Among the following, which one is such river that joins the Indus direct?
1. AChenab
2. BJhelum
3. CRavi
4. DSutlej
Answer and explanation
Correct answer: D
The Sutlej is the river that joins the Indus directly after receiving the collective drainage of the other three rivers. According to NCERT Class 11 (India: Physical Environment), the Jhelum and Ravi rivers join the Chenab, and the Chenab subsequently joins the Sutlej in Pakistan. The Sutlej then flows into the Indus a few kilometres above Mithankot. Thus, the Sutlej acts as the final conduit for the combined waters of the Jhelum, Ravi, and Chenab before their confluence with the Indus. This geographical sequence is confirmed by the official UPSC Answer Key for the 2021 Prelims, which identifies Option D as the correct answer.

In India, the central bank's function as the 'lender of last resort' usually refers to which of the following? 1. Lending to trade and industry bodies when they fail to borrow from other sources. 2. Providing liquidity to the banks having a temporary crisis. 3. Lending to governments to finance budgetary deficits. Select the correct answer using the code given below:
1. A1 and 2
2. B2 Only
3. C2 and 3
4. D3 Only
Answer and explanation
Correct answer: B
Statement 1 is incorrect. The 'lender of last resort' (LoLR) function of the central bank primarily applies to commercial banks and financial institutions, not trade and industry bodies. Businesses and industries generally rely on commercial banks, financial institutions, and capital markets for funds. The Reserve Bank of India (RBI) does not directly lend to trade and industry bodies under its LoLR function.
Statement 2 is correct. The central bank (RBI) acts as the 'lender of last resort' for commercial banks facing liquidity shortages. This helps prevent bank failures and maintains financial stability. RBI provides liquidity through mechanisms like repo operations, open market operations (OMO), and special liquidity facilities.
Statement 3 is incorrect. The RBI does not directly lend to the government to cover budgetary deficits under the 'lender of last resort' function. The government primarily finances deficits through market borrowings, treasury bills, and bonds. However, RBI can indirectly support the government by purchasing government securities in the open market (OMO) or monetizing debt in special situations (historically, through ways and means advances - WMA).

With reference to recent developments regarding 'Recombinant Vector Vaccines', consider the following statements: 1. Genetic engineering is applied in the development of these vaccines. 2. Bacteria and viruses are used as vectors. Which of the statements given above is/are correct?
1. A1 Only
2. B2 Only
3. CBoth 1 and 2
4. DNeither 1 nor 2
Answer and explanation
Correct answer: C
Statement 1 is Correct: Genetic engineering is fundamental to the development of recombinant vector vaccines. This process involves isolating the gene that codes for a specific antigen (a protein that triggers an immune response) from a pathogen and inserting it into the genetic material of a harmless carrier, known as a vector. Unlike recombinant protein vaccines (like Hepatitis B) where the antigen is produced in a lab, recombinant vector vaccines use the vector to deliver the genetic instructions directly into the human body.
Statement 2 is Correct: Both viruses and bacteria can serve as vectors in these vaccines. Viral vectors, such as Adenoviruses (used in the AstraZeneca/Covishield COVID-19 vaccine) or the Vesicular Stomatitis Virus (used in Ebola vaccines), are common. Bacterial vectors, such as attenuated strains of Salmonella or Mycobacterium bovis (BCG), are also used in research and development to deliver antigens and stimulate a robust immune response.

Consider the following statements: Other things remaining unchanged, market demand for a good might increase if 1. Price of its substitute increases 2. Price of its complement increases 3. The good is an inferior good and income of the consumers increases 4. Its price falls Which of the statements given above is/are correct?
1. A1 and 4 only
2. B2, 3 and 4
3. C1, 2 and 3
4. D1, 2, 3 and 4
Answer and explanation
Correct answer: A
Statement 1 is Correct: Substitutes are goods that can be used in place of each other. When the price of a substitute (e.g., tea) increases, the good in question (e.g., coffee) becomes relatively cheaper, leading consumers to switch to it and increasing its market demand.
Statement 2 is Incorrect: Complementary goods are consumed together (e.g., cars and petrol). According to standard economic principles (NCERT Class 12 Microeconomics), an increase in the price of a complement leads to a decrease in the demand for the good, as the total cost of using the two together rises.
Statement 3 is Incorrect: For an inferior good, there is an inverse relationship between income and demand. As the income of consumers increases, they tend to switch to superior or normal goods, causing the demand for the inferior good to decrease.
Statement 4 is Correct: According to the Law of Demand, other things remaining equal (ceteris paribus), a fall in the price of a good leads to an increase in the quantity demanded by consumers.

Water can dissolve more substances than any other liquid because
1. Ait is dipolar in nature
2. Bit is a good conductor of heat
3. Cit has high value of specific heat
4. Dit is an oxide of hydrogen
Answer and explanation
Correct answer: A
Water molecules are polar, meaning they have a positive charge on one end (the hydrogen atoms) and a negative charge on the other end (the oxygen atom). This polarity allows water molecules to attract and interact with other polar or charged molecules, facilitating the dissolution of a wide range of substances in water.
Therefore, option (a) is correct.

63World Geography
"Leaf litter decomposes faster than in any other biome and as a result the soil surface is often almost bare. Apart from trees, the vegetation is largely composed of plant forms that reach up into the canopy vicariously, by climbing the trees or growing as epiphytes, rooted on the upper branches of trees". This is the most likely description of
1. Aconiferous forest
2. Bdry deciduous forest
3. Cmangrove forest
4. Dtropical rain forest
Answer and explanation
Correct answer: D
The description provided is characteristic of the Tropical Rain Forest (Tropical Evergreen Forest).
- Rapid Decomposition: Tropical rain forests are characterized by high temperatures and high humidity throughout the year. These conditions facilitate intense microbial activity, causing leaf litter to decompose much faster than in any other biome. As a result, nutrients are quickly reabsorbed by plants, leaving the soil surface almost bare of organic matter. - Vegetation and Epiphytes: Due to the dense, multi-layered canopy, very little sunlight reaches the forest floor. To survive, many plant forms have adapted by climbing trees (lianas) or growing as epiphytes (plants that grow on the branches of trees to access sunlight without being parasitic). - Key Species: Common trees include Mahogany, Rosewood, Aini, and Ebony. - Distribution in India: According to NCERT, these forests are found in regions with heavy rainfall (over 200 cm), specifically the Western Ghats, the Northeastern states, and the Andaman & Nicobar Islands.
In contrast, coniferous forests have slow decomposition due to cold climates; dry deciduous forests have seasonal leaf fall and less dense canopies; and mangrove forests are specialized for saline coastal environments with distinct stilt roots.

Which one of the following is a reason why astronomical distances are measured in light-years?
1. ADistances among stellar bodies do not change.
2. BGravity of stellar bodies does not change.
3. CLight always travels in a straight line.
4. DSpeed of light is always same.
Answer and explanation
Correct answer: D
Statement A is incorrect: The distance between stellar bodies does change, but often very slowly or in predictable orbits. Planets orbit stars, stars orbit galactic centers, and galaxies orbit each other, all causing continuous changes in distance. And this statement is not related to why distance is measured in light years.
Statement B is incorrect: While the gravitational constant is fundamental, the effective gravity of stellar bodies changes due to shifts in their mass (e.g., fusion, stellar winds), changes in their radius/size (expanding into red giants, collapsing into white dwarfs/neutron stars), and changes in the distance between them as they orbit. And this statement is not related to why distance is measured in light years.
Statement C is incorrect: Though mostly light travels in a straight line, it can be bent by Gravity- phenomenon known as Gravitational Lensing.
Statement D is correct: the speed of light does not change in a vacuum. So, it is a constant that can be used for measurement.

With reference to Indian economy, demand pull-inflation can be caused/increased by which of the following? 1. Expansionary policies 2. Fiscal stimulus 3. Inflation-indexing wages 4. Higher - purchasing power 5. Rising interest rates Select the correct answer using the codes given below.
1. A1, 2 and 4 Only
2. B3, 4 and 5 Only
3. C1, 2, 3 and 5 Only
4. D1, 2, 3, 4 and 5
Answer and explanation
Correct answer: A
Expansionary policies: Expansionary policies like increased government spending or lower interest rates can stimulate economic activity and consumer spending. This can lead to excess demand that outstrips supply, causing prices to rise.
Fiscal stimulus: Similar to expansionary policies, fiscal stimulus through government spending injections can create an inflationary gap if it's excessive.
Higher purchasing power: Higher purchasing power can contribute to demand-pull inflation. If people have more money to spend due to factors like wage increases or wealth accumulation, it can lead to increased demand for goods and services.
Inflation-indexing wages: While inflation-indexing wages can contribute to a wage-price spiral in some cases, it's not necessarily a direct cause of demand-pull inflation. It can be a consequence of inflation rather than a primary driver.
Rising interest rates: Rising interest rates generally act as a tool to cool down an economy and reduce inflation. They make borrowing more expensive and encourage saving, thereby reducing the money supply and aggregate demand.
Therefore, the correct code is 1, 2, and 4.

1. A1 Only
2. B2 Only
3. CBoth 1 and 2
4. DNeither 1 nor 2
Answer and explanation
Correct answer: B
Statement 1 is incorrect. When we consider the distribution of water on Earth, we find that the amount of water in rivers and lakes is actually less than the amount of groundwater. This is because groundwater is stored in the Earth's crust, in the pores and spaces between rocks and soil, and it accounts for a significant portion of the Earth's fresh water. On the other hand, rivers and lakes, while visible and important for many ecosystems, actually hold a relatively small amount of the Earth's total water.
![Earth's Water Distribution](https://d39jluplm5thpx.cloudfront.net//earth_water_a28f612fc8.jpg)
Statement 2 is correct. The amount of water in polar ice caps and glaciers is indeed more than the amount of groundwater. This is because these ice caps and glaciers, particularly those in Antarctica and Greenland, hold the majority of the Earth's fresh water.

1. Aclonal propagation of crop plants.
2. Bdeveloping genetically modified crop plants.
3. Cproduction of plant growth substances.
4. Dproduction of biofertilizers.
Answer and explanation
Correct answer: B
Bollgard I and Bollgard II technologies are mentioned in the context of developing genetically modified (GM) cotton plants resistant to insect pests.
* Bollgard I: This was India's first commercially approved GM crop technology introduced in 2002. It incorporates a single gene (Cry1Ac) from the bacterium Bacillus thuringiensis (Bt) into cotton plants. This Bt gene produces an insecticidal protein that targets and kills certain insect pests, particularly the American Bollworm (Helicoverpa armigera).
* Bollgard II: This is a more advanced technology introduced in mid-2006. It incorporates two genes (Cry1Ac and Cry2Ab) from Bt into cotton. This provides broader resistance against a wider spectrum of insect pests, including lepidopteran caterpillars like the Spodoptera species, in addition to the American Bollworm.

We adopted parliamentary democracy based on the British model, but how does our model differ from that model? 1. As regards legislation, the British Parliament is supreme or sovereign but in India, the power of the Parliament to legislate is limited. 2. In India, matters related to the constitutionality of the Amendment of an Act of the Parliament are referred to the Constitution Bench by the Supreme Court Select the correct answer using the codes given below.
1. A1 Only
2. B2 Only
3. CBoth 1 and 2
4. DNeither 1 nor 2
Answer and explanation
Correct answer: C
Statement 1 is Correct: The key difference lies in Parliamentary Supremacy. In the British model, Parliament is considered sovereign. This means its legislative powers are supreme, and its laws cannot be challenged by any other body. In India, the Constitution is supreme. Parliament's power to legislate is limited by the Constitution. The judiciary can review laws passed by Parliament and strike them down if they violate the Constitution.
Statement 2 is also Correct: This is a specific example of the limitation on Parliament's power in India. The Constitution Bench of the Supreme Court has the authority to review amendments made to existing laws (Acts) and determine if they are constitutional. This power of judicial review ensures the Constitution remains the supreme law.

What was the exact constitutional status of India on 26th January 1950?
1. AA Democratic Republic
2. BA Sovereign Democratic Republic
3. CSovereign Secular Democratic Republic
4. DA Sovereign Socialist Secular Democratic Republic
Answer and explanation
Correct answer: B
The exact constitutional status of India on 26th January 1950 was a Sovereign Democratic Republic.
- The Constitution of India was adopted on 26th November 1949, but it came into effect on 26th January 1950. - The Preamble of the Constitution, adopted in 1949, defined India as a "Sovereign Democratic Republic." - The terms "Socialist" and "Secular" were added to the Preamble much later, through the 42nd Amendment Act of 1976.
Therefore, on 26th January 1950, India wasn't yet classified as "Socialist" or "Secular" in its constitution.

Its design has given rise to a popular belief that it was the inspiration behind the Indian Parliament building. Which of the statements given above are correct?
1. A1 and 2
2. B2 and 3 Only
3. C1 and 4
4. D2, 3 and 4
Answer and explanation

In case of which one of the following biogeochemical cycles, the weathering of rocks is the main source of release of nutrient to enter the cycle?
1. ACarbon cycle
2. BNitrogen cycle
3. CPhosphorus Cycle
4. DSulphur Cycle
Answer and explanation
Correct answer: C
The Phosphorus Cycle is unique among major biogeochemical cycles because it does not involve a gaseous phase. Instead, phosphorus primarily moves through the lithosphere (rocks), hydrosphere (water), and biosphere (organisms).
- Weathering of Rocks: The main source of phosphorus in this cycle comes from the weathering of phosphate-rich rocks. Over time, geological processes break down these rocks, releasing phosphate ions (PO₄³⁻) into the soil and water. - Absorption by Plants: Plants absorb phosphorus from the soil, and it moves up the food chain as herbivores and carnivores consume plants and other organisms. - Return to the Soil: When organisms die, decomposition releases phosphorus back into the environment, where it can re-enter the cycle. ![Phosphorus Cycle](https://d39jluplm5thpx.cloudfront.net//phosphorus_cycle_46e60589a9.jpg)
- Carbon Cycle: The main source of carbon is atmospheric CO₂, released by respiration, combustion, and volcanic activity. ![Carbon Cycle](https://d39jluplm5thpx.cloudfront.net//carbon_cycle_326ba82622.jpg)
- Nitrogen Cycle: Nitrogen is primarily cycled through the atmosphere, with nitrogen fixation (by bacteria) being a key process. ![Nitrogen Cycle](https://d39jluplm5thpx.cloudfront.net//nitrogen_cycle_e29b12f7a6.JPG)
- Sulphur Cycle: Sulfur is mainly released from volcanic eruptions, decaying organic matter, and fossil fuel combustion, rather than rock weathering. ![Sulphur Cycle](https://d39jluplm5thpx.cloudfront.net//sulfur_cycle_ca4db2b2c8.jpg)

Consider the following statements: The effect of devaluation of a currency is that it necessarily:- 1. improves the competitiveness of the domestic exports in the foreign markets. 2. increases the foreign value of domestic currency. 3. improves the trade balance. Which of the above statements is/are correct?
1. A1 Only
2. B1 and 2
3. C3 Only
4. D2 and 3
Answer and explanation
Correct answer: A
Statement 1 is correct. When a country devalues its currency, it becomes cheaper for foreign buyers to purchase the country's exports. This can lead to increased demand for exports, making domestic producers more competitive in the international market.
Statement 2 is incorrect. Devaluation actually decreases the foreign value of the domestic currency. The whole point is to make the domestic currency less expensive relative to foreign currencies.
Statement 3 is also incorrect. While improved export competitiveness can lead to a better trade balance (more exports, fewer imports), it's not a guaranteed outcome. Other factors like import prices, global demand, and domestic production costs can also influence the trade balance. Devaluation can also lead to increased import costs if the country relies on imported raw materials.
Therefore, the correct code is 1 only.

Why is there a concern about copper smelting plants? 1. They may release lethal quantities of carbon monoxide into environment. 2. The copper slag can cause the leaching of some heavy metals into environment. 3. They may release sulphur dioxide as a pollutant. Select the correct answer using the codes given below.
1. A1 and 2 Only
2. B2 and 3 Only
3. C1 and 3 Only
4. D1, 2 and 3
Answer and explanation
Correct answer: B
Statement 1 is Incorrect: Copper smelting plants are not typically associated with the release of lethal quantities of carbon monoxide into the environment; the primary gaseous pollutant of concern is sulfur dioxide. Statement 2 is Correct: Copper slag is a byproduct of the smelting process that contains heavy metals such as arsenic, lead, and cadmium. These metals can leach into the environment, potentially contaminating soil and groundwater resources. Statement 3 is Correct: Copper smelting plants are a major source of sulfur dioxide (SO2) emissions. This occurs because most copper ores are sulfide minerals (like chalcopyrite), and the sulfur within the ore is oxidized and released as SO2 gas during the roasting and smelting processes.

Which one of the following factors constitutes the best safeguard of liberty in a liberal democracy?
1. AA committed judiciary
2. BCentralization of powers
3. CElected government
4. DSeparation of powers
Answer and explanation
Correct answer: D
* The Separation of Powers between the legislature, the executive, and the judiciary constitute an important safeguard of liberty in a liberal democracy.
* The doctrine of Separation of powers entails the division of the legislative, executive, and judicial functions of government among different organs. This separation minimizes the possibility of arbitrary excesses by the government since all three organs act as checks and balances on the powers of each other. Therefore, none of the three organs can usurp the essential functions of other organs.
* This demarcation prevents the concentration of excessive power by any branch of the Government. It thus helps to safeguard the liberty and rights of the people in a democracy.

In a pressure cooker, the temperature at which the food is cooked depends mainly upon which of the following? 1. Area of the hole in the lid. 2. Temperature of the flame 3. Weight of the lid Select the correct answer using the code given below.
1. A1 and 2 Only
2. B2 and 3 Only
3. C1 and 3 Only
4. D1, 2 and 3
Answer and explanation
Correct answer: C
Statement 1 is correct: The size of the hole in the lid regulates the amount of steam released. A larger hole permits more steam to escape, leading to reduced pressure and subsequently affecting the temperature.
Statement 2 is incorrect: Boiling water can never exceed 100 degrees Celsius, regardless of the intensity of the flame beneath the pot. However, within a pressure cooker, the temperature can elevate to as high as 121 degrees Celsius. The heightened cooking temperature serves to decrease the cooking duration rather than the temperature itself.
Statement 3 is correct: If the weight is heavier, it will require higher pressure to lift it, resulting in higher pressure inside the cooker before excess steam can escape. Higher pressure leads to a higher boiling point for the water inside the cooker, which in turn increases the cooking temperature. Conversely, if the weight is lighter, it results in a lower pressure inside the cooker and a lower boiling point for the water, leading to a lower cooking temperature.

With reference to 'Urban Cooperative Banks' in India, consider the following statements: 1. They are supervised and regulated by local boards set up by the State Governments. 2. They can issue equity shares and preference shares. 3. They were brought under the purview of the Banking Regulation Act, 1949 through an Amendment in 1966. Which of the statements given above is/are correct?
1. A1 only
2. B2 and 3 only
3. C1 and 3 only
4. D1, 2 and 3
Answer and explanation
Correct answer: B
Statement 1 is incorrect. Urban Cooperative Banks (UCBs) are not solely regulated by State Governments. They are jointly regulated by the Reserve Bank of India (RBI) and the respective State Governments. In 2020, the Banking Regulation (Amendment) Act, 2020 gave RBI more control over UCBs, bringing them largely under its regulatory framework for financial stability.
Statement 2 is correct. As per the Banking Regulation (Amendment) Act, 2020, Urban Cooperative Banks can raise funds by issuing equity shares, preference shares, and unsecured debentures with RBI approval. This allows UCBs to strengthen their capital base and improve financial health.
Statement 3 is correct. Initially, cooperative banks were regulated under state laws. In 1966, an amendment to the Banking Regulation Act, 1949, brought Urban Cooperative Banks (UCBs) under RBI's purview for banking-related functions. However, their management and administrative aspects remained under state cooperative laws.

The money multiplier in an economy increases with which one of the following?
1. AIncrease in the Cash Reserve Ratio in the banks.
2. BIncrease in the Statutory Liquidity Ratio in the banks.
3. CIncrease in the banking habit of the people.
4. DIncrease in the population of the country.
Answer and explanation
Correct answer: C
Statement A is incorrect: Increase in the Cash Reserve Ratio (CRR) in banks. CRR is the percentage of deposits banks must keep with the RBI. If CRR increases, banks have less money to lend, reducing the money multiplier.
Statement B is incorrect: Increase in the Statutory Liquidity Ratio (SLR) in banks. SLR is the percentage of deposits banks must keep in liquid assets like gold or government securities. A higher SLR means less lending capacity, reducing the money multiplier.
Statement C is correct: Increase in the banking habits of the people. If more people deposit money in banks instead of holding cash, banks get more reserves to lend, increasing the money multiplier. This expands the credit creation process, leading to a higher money supply.
Statement D is incorrect: Increase in the population of the country. A higher population does not directly impact the money multiplier unless it leads to a rise in banking habits or economic activity.

Foreign Direct Investment (FDI) refers to the investment through capital instruments by a person resident outside India in an unlisted Indian company, or in 10% or more of the post-issue paid-up equity capital of a listed Indian company.
* Statements 1 and 3 are correct: Foreign Currency Convertible Bonds (FCCBs) and Global Depository Receipts (GDRs) are instruments used by Indian companies to raise capital from foreign markets. Under the FDI policy of the Government of India, investments made through these instruments are treated as part of the FDI framework because they represent or convert into equity shares of the company. * Statement 2 is correct: While Foreign Institutional Investment (FII) is generally categorized as Portfolio Investment, the Arvind Mayaram Committee recommended that any investment by a foreign investor/FII/FPI that exceeds 10% of the equity of an Indian company should be treated as FDI. Thus, with the condition of reaching the 10% threshold, FII is included in FDI. * Statement 4 is incorrect: Non-Resident External (NRE) deposits are bank accounts maintained by NRIs in Indian banks. These are classified as 'Banking Capital' or 'External Debt' (if repatriable) and are not considered as Foreign Direct Investment in a productive enterprise.

With reference to 8th August 1942 in Indian history, which one of the following statements is correct?
1. AThe Quit India Resolution was adopted by the AICC.
2. BThe Viceroy's Executive council was expanded to include more Indians.
3. CThe Congress ministries resigned in seven provinces.
4. DCripps proposed an Indian Union with full Dominion Status once the Second World War was over.
Answer and explanation
Correct answer: A
On 8th August 1942, the Quit India Resolution was adopted by the All India Congress Committee (AICC). This was a significant event in the Indian freedom struggle as it marked the launch of the Quit India Movement, led by Mahatma Gandhi, demanding an end to British Rule in India.
The other options are not related to this specific date. - The Viceroy's Executive council was indeed expanded to include more Indians, but this was part of the August Offer in 1940, not on 8th August 1942. - The Congress ministries did resign in seven provinces, but this happened in 1939, not in 1942. - Lastly, Cripps did propose an Indian Union with full Dominion Status, but this was part of the Cripps Mission, which also did not occur on 8th August 1942.
Therefore, the correct answer is that the Quit India Resolution was adopted by the AICC on this date.

Which one of the following is likely to be the most inflationary in its effects?
1. ARepayment of Public debt.
2. BBorrowing from the public to finance a budget deficit.
3. CBorrowing from the banks to finance a budget deficit.
4. DCreation of new money to finance a budget deficit.
Answer and explanation
Correct answer: D
The most inflationary method of financing a budget deficit is the creation of new money.
Option A is incorrect: Repayment of public debt involves the government transferring money back to the creditors (the public). This increases the liquidity and money supply in the hands of the public. However, it is generally less inflationary than printing new money because the funds used for repayment often come from tax revenues, which reduces the disposable income of the public elsewhere.
Option B is incorrect: Borrowing from the public involves a transfer of existing money from individuals and private institutions to the government. Since the total money supply in the economy remains the same (it just changes hands), this is considered the least inflationary way to finance a deficit.
Option C is incorrect: Borrowing from commercial banks can lead to an increase in the money supply if banks use their excess reserves to lend to the government, potentially leading to credit creation. While more inflationary than borrowing from the public, its impact is still significantly lower than the direct creation of new money.
Option D is correct: Creation of new money (often called deficit financing or monetization of debt) occurs when the central bank prints new currency to fund government expenditure. This directly increases the 'high-powered money' or monetary base in the economy. This expansion of the money supply, without a corresponding increase in the production of goods and services, leads to a sharp rise in price levels, making it the most inflationary option.

India Government Bond Yields are influenced by which of the following? 1. Actions of the United States Federal Reserve. 2. Actions of the Reserve Bank of India. 3. Inflation and short-term interest rates. Which of the statements given above is/are correct?
1. A1 and 2 only
2. B2 Only
3. C3 Only
4. D1, 2 and 3
Answer and explanation
Correct answer: D
Statement 1 is correct: The Federal Reserve's monetary policy decisions, particularly regarding interest rates, can impact global capital flows. If the Fed raises interest rates, it can make US investments more attractive, potentially leading to some outflow of capital from India. This could affect demand for Indian government bonds and influence their yield.
Statement 2 is correct: The RBI's monetary policy plays a crucial role in influencing Indian government bond yields. The RBI's actions like setting repo rates, open market operations, and cash reserve ratio (CRR) can affect the overall liquidity in the banking system. Higher liquidity can lead to lower yields, and vice versa.
Statement 3 is correct: Inflation expectations and short-term interest rates are important factors for investors when considering the return on government bonds. Higher inflation expectations can lead investors to demand higher yields to compensate for the potential erosion of purchasing power. Similarly, short-term interest rates can act as a benchmark for bond yields.
Therefore, all three factors significantly influence the yields of Indian government bonds.
