Read the passage (Passage—1) — this item is based on it

We often hear about conflicts among different States in India over river waters. Of the 20 major river systems, 14 are already water-stressed; 75% of the population lives in water-stressed regions, a third of whom live in water-scarce areas. Climate change, the demands of rising population and the need for agriculture to keep pace, and increased rate of urbanization and industrialization will exacerbate water stress. According to the Constitution of India, water is a State subject and not that of the Union, except for regulation of inter-State rivers. Key to ensuring balance between competing demands of various stakeholders is a basin-based approach to allocate water amongst constituent regions and States. Allocating fair share of water to them requires assessments based on objective criteria, such as specificities of the river basin, size of dependent population, existing water use and demand, efficiency of use, projected future use, etc. while ensuring the environmental needs of the river and aquifers.

Which one of the following statements best reflects the most rational, practical and immediate action required to ensure fair and equitable allocation of water to different stakeholders?

Answer & explanation

Answer: (a) A national, pragmatic, legal and policy framework for water allocation should be made.

The passage says fair sharing needs a basin-based approach and shares fixed on objective criteria, which means agreed rules for allocation. A national legal and policy framework is the only option that supplies such rules; the others are engineering or demand-side ideas the passage never proposes.

✓ (a) The passage's key is 'a basin-based approach' with shares assessed on 'objective criteria'. A national legal and policy framework is the practical way to apply such rules across States, especially as water is a State subject.
✗ (b) Linking every river and creating huge aquifers is a vast engineering project, neither immediate nor mentioned; the passage is about sharing existing water fairly.
✗ (c) Channels from surplus to deficit regions move water, but they do not settle who gets how much; the passage never suggests them.
✗ (d) Cutting demand may ease stress, but the question asks how to allocate water fairly among stakeholders, which demand cuts do not decide.

Remember · For 'most rational, practical, immediate action', pick the option that puts the passage's own solution into practice; reject grand projects it never mentions.

Read the passage (Passage—2) — this item is based on it

More than half of Indian women and almost a quarter of Indian men of working age suffer from anaemia. According to studies, they are anywhere from 5 – 15% less productive than they could be, as a result thereof. India also has the largest tuberculosis burden in the world, costing 170 million workdays to the country annually. But what is just as important as lost productivity now is lost potential in the future. It is becoming increasingly clear that on many measures of cognitive ability, malnourished Indian children perform two or three times worse than their adequately nourished peers. For an economy that will be more dependent on highly skilled workers, this poses a significant challenge. And it is one that really should be addressed given India's demographic outlook.

Which one of the following statements best reflects what is implied by the passage?

Answer & explanation

Answer: (d) For rapid economic growth as envisaged by us, attention should be paid to health and nutrition of the people.

Anaemia and tuberculosis cut today's productivity, and child malnutrition cuts tomorrow's cognitive potential, which matters for an economy that will need skilled workers. The implied message is that growth depends on attention to people's health and nutrition.

✗ (a) Education and rural areas are not discussed; the problem identified is ill-health and malnutrition.
✗ (b) Skill programmes are not the remedy offered; the passage argues that malnutrition limits the very capacity to become highly skilled.
✗ (c) 'Only skilled workers' is wrong: the passage speaks of women, men of working age and children.
✓ (d) Lost productivity (anaemia, TB) and lost future potential (malnourished children) both point to health and nutrition as the base of economic growth.

Remember · When a passage lists a problem and its economic cost, the implication is to fix that root problem, not a neighbouring policy.

Easy

Read the passage (Passage—3) — this item is based on it

In India, a majority of farmers are marginal and small, less educated and possess low adaptive capabilities to climate change, perhaps because of credit and other constraints. So, one cannot expect autonomous adaptation to climate change. Even if it was possible, it would not be sufficient to offset losses from climate change. To deal with this, adaptation to climate change is paramount, alongside a fast mitigation response. Another solution is to have a planned or policy-driven adaptation, which would require the government to come up with policy recommendations. Perception is a necessary pre-requisite for adaptation. Whether farmers are adapting agricultural practices to climate change depends on whether they perceive it or not. However, this is not always enough for adaptation. It is important how a farmer perceives the risks associated with climate change.

Which one of the following statements best reflects the most logical and rational message conveyed by the author of the passage?

Answer & explanation

Answer: (c) Risk perceptions of farmers are important for motivating them for taking adaptation decisions.

The passage builds up to the point that perception is a pre-requisite for adaptation and that what matters is how a farmer perceives the risks of climate change. So farmers' risk perception drives their decision to adapt.

✗ (a) Policy-driven adaptation is called 'another solution'; the passage never makes adaptation and mitigation basically the government's job.
✗ (b) Land-use policies are not mentioned at all.
✓ (c) 'Perception is a necessary pre-requisite for adaptation' and 'It is important how a farmer perceives the risks' say exactly this.
✗ (d) The passage wants adaptation 'alongside a fast mitigation response'; it never says mitigation is not possible.

Remember · The author's message usually sits where the argument ends; test extreme words such as 'basically', 'only' and 'not possible' against the text.

Easy

Read the passage (Passage—1) — this item is based on it

The emissions humans put into the atmosphere now will affect the climate in the middle of the century and onwards. Technological change, meanwhile, could make a future transition away from fossil fuels cheap or it might not, leaving the world with a terrible choice between sharply reducing emissions at huge cost or suffering through the effects of unabated warming. Businesses that do not hedge against the threat of uncertain outcomes fail. The world cannot afford such recklessness on climate change.

Which one of the following statements best reflects the crucial message conveyed by the author of the passage?

Answer & explanation

Answer: (c) Waiting to deal with carbon emissions until technology improves is not a wise strategy.

Emissions released now shape the climate decades later, and cheap clean technology may or may not arrive. Just as businesses that do not hedge against uncertainty fail, the world cannot gamble on future technology, so waiting for it before cutting emissions is unwise.

✗ (a) Closing down or paying for pollution is not discussed; businesses appear only as an example of hedging against uncertainty.
✗ (b) The passage says technology 'could make a future transition ... cheap or it might not', so it denies that technology is a sure, let alone the only, solution.
✓ (c) Betting on uncertain future technology instead of acting now is the 'recklessness' the world 'cannot afford'.
✗ (d) New industries and renewables are not the point; the passage is about hedging against uncertainty by acting on emissions now.

Remember · When a passage uses an analogy, the message is the analogy's lesson applied to the main subject.

Read the passage (Passage—2) — this item is based on it

Environmental problems cause health problems. Substantial changes in lifestyle can reduce environmental or health problems, but this idea appears almost impossible to adopt. With environmental problems, individual efforts can be perceived as having a negligible effect and therefore lead to inertia. With health, on the other hand, individual choices can make the difference between life and death, literally. And yet, barring a few, there seems to be the same collective lethargy towards making their choices.

Which one of the following statements best implies the most rational assumption that can be made from the passage?

Answer & explanation

Answer: (a) We are likely to spend more money on cure than prevention.

Lifestyle changes could prevent environmental and health problems, yet people show 'collective lethargy' even where their own choices decide life and death. When prevention is neglected, the problems arrive and must be treated, so more is likely to be spent on cure than on prevention.

✓ (a) Inertia towards healthy lifestyle choices means prevention is neglected; the logical result is heavier spending on cure later.
✗ (b) The government is not mentioned; the passage is about individual choices and collective lethargy.
✗ (c) The opening line, 'Environmental problems cause health problems', rules out protecting health while environmental problems are ignored.
✗ (d) Traditional lifestyles and western values are outside the passage.

Remember · A valid assumption follows from the passage's own logic; options that bring in new actors or causes (government, western values) usually fail.

Easy

Read the passage (Passage—3) — this item is based on it

Many people are not eating the right food. For some, it is simply a decision to stick with food they enjoy but which is not too healthy. This is leading to an increase in non-communicable diseases. This in turn leads to major burden on our health-care systems that have the potential to derail the economic progress which is essential for the poor to improve their lives. For others, it is about limited access to nutritious food or a lack of affordability, leading to monotonous diets that do not provide the daily nutrients for them to develop fully. Part of the reason nutrition is under threat worldwide is that our food systems are not properly responding to nutritional needs. Somewhere along that long road from farm to fork, there are serious detours taking place.

Which one of the following statements best reflects the crux of the passage?

Answer & explanation

Answer: (b) We must place food-based nutrition at the centre of our policy debate.

The passage traces poor nutrition to unhealthy food choices, poor access and poor affordability, and blames food systems that are not responding to nutritional needs 'from farm to fork'. Its crux is that nutrition through food must be central to policy.

✗ (a) Universal Basic Income is not mentioned; affordability is only one of several causes described.
✓ (b) The closing idea, that 'our food systems are not properly responding to nutritional needs', calls for making food-based nutrition the centre of policy.
✗ (c) Genetically modified crops are outside the passage.
✗ (d) Fortification is a specific technique the passage does not discuss, and it would not address the choice and access problems described.

Remember · The crux covers all the causes a passage lists; specific technical fixes such as GM crops or fortification are usually too narrow.

CSAT 2023 · Q21

Easy

Read the passage (Passage—1) — this item is based on it

To tackle the problem of pollution in cities, policy makers think that drastic actions like temporary use of odd-even number scheme for vehicles, closing schools, factories, construction activities, and banning the use of certain type of vehicles are a way forward. Even then the air is not clean. Vehicles more than 15 years old comprise one percent of the total; and taking them off the road will not make any difference. Banning certain fuels and car types arbitrarily is not proper. Diesel engines produce more PM 2.5 and less CO₂ than petrol or CNG engines. On the other hand, both diesel and CNG engines produce more NOₓ than petrol engines. No one has measured the amount of NOₓ that CNG engines are emitting. Arbitrary bans on vehicles that have passed mandated fitness tests and periodic pollution tests are unfair. What is needed is the scientific and reliable information about the source of pollutants on a continuing basis and the technologies that will work to reduce pollution from them.

Which one of the following statements best reflects the most logical and rational implication conveyed by the passage?

Answer & explanation

Answer: (b) Knee-jerk reactions cannot solve the problem of pollution but an evidence-based approach will be more effective.

The author finds drastic, arbitrary measures (odd-even, bans on old vehicles and certain fuels) ineffective and unfair, and closes by asking for scientific, reliable information on pollution sources and on technologies that work. In short: evidence, not knee-jerk action.

✗ (a) The passage calls arbitrary bans ineffective, 'not proper' and 'unfair', not difficult to implement.
✓ (b) Drastic actions leave 'the air ... not clean', and the author ends with 'What is needed is the scientific and reliable information' — an evidence-based approach.
✗ (c) No penalty is proposed; the passage defends vehicles that have passed fitness and pollution tests.
✗ (d) The passage never says pollution laws are absent or that this causes arbitrary decisions.

Remember · Read the closing 'what is needed' sentence; the implication usually restates it. Reject options about ease, penalties or laws never discussed.

Read the passage (Passage—2) — this item is based on it

Good corporate governance structures encourage companies to provide accountability and control. A fundamental reason why corporate governance has moved onto the economic and political agenda worldwide has been the rapid growth in international capital markets. Effective corporate governance enhances access to external financing by firms, leading to greater investment, higher growth and employment. Investors look to place their funds where the standards of disclosure, of timely and accurate financial reporting, and of equal treatment to all stakeholders are met.

Which of the following statements best reflects the logical inference from the passage given above?

Answer & explanation

Answer: (b) Good corporate governance improves the credibility of the firms.

Good governance brings accountability and control, and investors put money where disclosure, accurate reporting and fair treatment of stakeholders are assured, which is why such firms get easier external finance. The inference is that good governance makes firms more credible.

✗ (a) The passage says corporate governance moved onto the global agenda; it does not say ensuring access to external financing is countries' agenda.
✓ (b) Accountability, control, timely and accurate reporting and equal treatment are the standards investors trust, so good governance raises a firm's credibility and its access to funds.
✗ (c) This reverses the link: the growth of capital markets is why governance became important; markets are not said to ensure good governance.
✗ (d) Supply chains are not mentioned.

Remember · Watch for reversed cause and effect: an option that swaps the passage's cause and result is a classic trap.

Easy

Read the passage (Passage—3) — this item is based on it

Elephants are landscape architects, creating clearings in the forest, preventing overgrowth of certain plant species and allowing space for the regeneration of others, which in turn provide sustenance to other herbivorous animals. Elephants eat plants, fruits and seeds, propagating the seeds when they defecate in other places as they travel. Elephant dung provides nourishment to plants and animals and acts as a breeding ground for insects. In times of drought, they access water by digging holes which benefits other wildlife.

Which one of the following statements best reflects the most logical and rational inference that can be drawn from the passage?

Answer & explanation

Answer: (b) Elephants are the keystone species and they benefit the biodiversity.

Elephants make clearings, check overgrowth, spread seeds, enrich the soil with dung and dig water holes, and each of these helps other plants and animals. A species whose activities shape the whole ecosystem in this way is a keystone species that benefits biodiversity.

✗ (a) The size or richness of the elephants' home range is not discussed.
✓ (b) Every example shows elephants sustaining other plants, herbivores, insects and wildlife — the role of a keystone species.
✗ (c) 'Cannot be maintained without elephants' goes too far; the passage shows benefit, not that biodiversity is impossible without them.
✗ (d) Regeneration is a side-effect of their feeding and movement; 'as per their requirement' implies a deliberate design the passage never claims.

Remember · Choose the inference that sums up all the examples; reject 'cannot', 'only' and intentions the passage never attributes.

Read the passage (Passage—1) — this item is based on it

In India, the segregation of municipal waste at source is rare. Recycling is mostly with the informal sector. More than three-fourths of the municipal budget goes into collection and transportation, which leaves very little for processing/resource recovery and disposal. Where does waste-to-energy fit into all this? Ideally it fits in the chain after segregation (between wet waste and the rest), collection, recycling, and before getting to the landfill. Which technology is most appropriate in converting waste to energy depends on what is in the waste (that is biodegradable versus non-biodegradable component) and its calorific value. The biodegradable component of India's municipal solid waste is a little over 50 per cent, and biomethanation offers a major solution for processing this.

Based on the above passage, the following assumptions have been made:

1.Collection, processing and segregation of municipal waste should be with government agencies.
2.Resource recovery and recycling require technological inputs that can be best handled by private sector enterprises.

Which of the assumptions given above is/are correct?

Answer & explanation

Answer: (d) Neither 1 nor 2

The passage describes rare segregation, informal recycling and a budget swallowed by collection and transport, and explains where waste-to-energy fits and how technology should be chosen. It never says who — government agencies or private firms — should do these jobs, so neither assumption is made.

✗ 1. The passage notes that recycling is with the informal sector and how the municipal budget is spent, but it never says which agency should collect, process or segregate waste.
✗ 2. Technology choice is tied to the waste's composition and calorific value; the private sector is not mentioned at all.

Remember · An assumption must be needed for the author's argument; statements that assign a job to a new actor (government, private sector) usually are not.

Read the passage (Passage—1) — this item is based on it

Which one of the following statements best reflects the crux of the passage?

Answer & explanation

Answer: (c) Segregation of municipal solid waste is the first step in ensuring the success of waste-to-energy plants.

Waste-to-energy fits in the chain after segregation, and the right technology depends on what the waste contains, yet segregation at source is rare in India. So segregation is the first requirement for waste-to-energy plants to work.

✗ (a) The cost of waste-to-energy is not discussed; the budget point is that collection and transport take most of the money.
✗ (b) Biomethanation is 'a major solution' for the biodegradable part, not the most ideal way for all municipal waste.
✓ (c) Waste-to-energy 'fits in the chain after segregation', and technology depends on the waste's make-up, which cannot be handled well while segregation at source is 'rare'.
✗ (d) The biodegradable share is 'a little over 50 per cent' and biomethanation can process it — the opposite of 'not adequate'.

Remember · The crux links the passage's problem (rare segregation) to its solution chain; reject superlatives like 'most ideal' that the passage never uses.

Read the passage (Passage—2) — this item is based on it

There is a claim that organic farming is inherently safer and healthier. The reality is that because the organic farming industry is still young and not well-regulated in India, farmers and consumers, alike, are not only confused about what products are best for them, but sometimes use products in ways that could harm them as well. For example, since organic fertilizers are difficult to obtain on a large scale in India, farmers often use farmyard manure, which may contain toxic chemicals and heavy metals. Certain plant sprays, such as Datura flower and leaf spray, have an element called atropine. If it is not applied in the right dose, it can act on the nervous system of the consumer. Unfortunately, how much and when to use it are not well-researched or regulated issues.

Based on the above passage, the following assumptions have been made:

1.Organic farming is inherently unsafe for both farmers and consumers.
2.Farmers and consumers need to be educated about eco-friendly food.

Which of the assumptions given above is/are correct?

Answer & explanation

Answer: (b) 2 only

The author disputes the claim that organic farming is inherently safer, but traces the dangers to a young, poorly regulated industry and to confusion and misuse by farmers and consumers. So the passage assumes they need to be better informed, not that organic farming is unsafe by nature.

✗ 1. The risks come from poor regulation, substitutes such as contaminated manure and wrong doses of sprays, not from organic farming itself; 'inherently unsafe' goes too far.
✓ 2. Farmers and consumers are 'confused about what products are best for them' and use products in harmful ways, which presumes that educating them would help.

Remember · Rejecting 'inherently safe' does not mean 'inherently unsafe'; watch for options that flip a claim to its extreme opposite.

Which one of the following statements best reflects the most logical, rational and practical message conveyed by the author of the passage?

Answer & explanation

Answer: (c) In India, farmers need to be guided and helped to make their organic farming sustainable.

Farmers misuse inputs such as farmyard manure and Datura spray because the sector is young, poorly regulated and under-researched. The practical message is that farmers need guidance and support to make organic farming safe and sustainable.

✗ (a) The passage does not compare organic with conventional farming or argue against promoting organic farming.
✗ (b) 'No safe organic alternatives' is too extreme; the problem is misuse and weak regulation, not the absence of safe options.
✓ (c) Confusion, harmful use and unresearched doses all point to the need to guide and help farmers.
✗ (d) Profits and global markets are outside the passage.

Remember · For a 'practical message', choose the constructive remedy that answers the problems described; reject blanket negatives and outside topics.

Read the passage (Passage—3) — this item is based on it

Food consumption patterns have changed substantially in India over the past few decades. This has resulted in the disappearance of many nutritious foods such as millets. While food grain production has increased over five times since independence, it has not sufficiently addressed the issue of malnutrition. For long, the agriculture sector focussed on increasing food production particularly staples, which led to lower production and consumption of indigenous traditional crops/grains, fruits and other vegetables, impacting food and nutrition security in the process. Further, intensive, monoculture agriculture practices can perpetuate the food and nutrition security problem by degrading the quality of land, water and food derived through them.

Based on the above passage, the following assumptions have been made:

1.To implement the Sustainable Development Goals and to achieve zero-hunger goal, monoculture agriculture practices are inevitable even if they do not address malnutrition.
2.Dependence on a few crops has negative consequences for human health and the ecosystem.
3.Government policies regarding food planning need to incorporate nutritional security.
4.For the present monoculture agriculture practices, farmers receive subsidies in various ways and government offers remunerative prices for grains and therefore they do not tend to consider crop diversity.

Which of the above assumptions are valid?

Answer & explanation

Answer: (b) 2 and 3 only

The passage blames the long focus on staples and intensive monoculture for the decline of nutritious crops and for degrading land, water and food, even as grain output rose without ending malnutrition. It therefore assumes that dependence on a few crops harms health and ecosystems, and that food planning must include nutrition.

✗ 1. The passage criticises monoculture for perpetuating the nutrition problem; it never calls it inevitable for the SDGs or zero hunger.
✓ 2. The focus on staples pushed out nutritious crops (health), and monoculture degrades 'land, water and food' (ecosystem).
✓ 3. Grain output rose over five times yet malnutrition persists, so food planning must aim at nutrition, not quantity alone.
✗ 4. Subsidies and remunerative prices are not mentioned; this explanation is brought in from outside the passage.

Remember · Valid assumptions follow from the passage's own reasoning; reject facts brought in from outside, even if true in real life.

Read the passage (Passage—1) — this item is based on it

Scientists studied the vernal window — transition period from winter to the growing season. They found that warmer winters with less snow resulted in a longer lag time between spring events and a more protracted vernal window. This change in the spring timetable has ecological, social and economic consequences — for agriculture, fisheries and tourism. As the ice melts earlier, the birds don't return, causing a delay, or lengthening in springtime ecological events.

With reference to the above passage, the following assumptions have been made:

1.Global warming is causing spring to come early and for longer durations.
2.Early spring and longer period of spring is not good for bird populations.

Which of the above assumptions is/are correct?

Answer & explanation

Answer: (a) 1 only

The passage links warmer winters with less snow to earlier ice-melt and a longer, more drawn-out vernal window, which takes a warming climate to be making spring come early and last longer. It reports that birds do not return on time, but says nothing about harm to bird populations.

✓ 1. 'Warmer winters with less snow' produce 'a more protracted vernal window' and ice that 'melts earlier': the passage takes it that warming brings spring earlier and stretches it out.
✗ 2. The passage says the birds don't return, delaying springtime events; it says nothing about bird numbers, so harm to bird populations is not assumed.

Remember · Separate what a passage reports (birds' timing changes) from a further judgement it never makes (populations suffer).

Read the passage (Passage—2) — this item is based on it

A global analysis of nitrogen use efficiency — a measure of the amount of nitrogen a plant takes in to grow versus what is left behind as pollution — says that using too much fertilizers will lead to increased pollution of waterways and the air. Currently, the global average for nitrogen use efficiency is approximately 0.4, meaning 40 per cent of the total nitrogen added to cropland goes into the harvested crop while 60 per cent is lost to the environment, says a study. More than half of the world's population is nourished by food grown with fertilizers containing synthetic nitrogen, which is needed to produce high crop yields. Plants take the nitrogen they need to grow, and the excess is left in the ground, water and air. This results in significant emissions of nitrous oxide, a potent greenhouse and ozone depleting gas, and other forms of nitrogen pollution, including eutrophication of lakes and rivers and contamination of river water.

Which one of the following statements best reflects the most logical, rational and crucial message implied by the passage?

Answer & explanation

Answer: (a) An enhanced efficiency of use of nitrogen is imperative for both food production and environment.

Synthetic nitrogen feeds more than half the world, yet 60 per cent of the nitrogen applied is lost as pollution. The balanced message is to use nitrogen more efficiently, keeping yields up while cutting pollution.

✓ (a) The passage is built around 'nitrogen use efficiency': synthetic nitrogen is 'needed to produce high crop yields', but low efficiency (0·4) pollutes air and water. Higher efficiency serves both food and environment.
✗ (b) Stopping fertilizer production is never discussed; the option defends a point the passage does not raise.
✗ (c) Replacing crops is not suggested; the problem is excess application, not the crops themselves.
✗ (d) Replacing conventional agriculture is too drastic when the passage says synthetic nitrogen nourishes over half the world.

Remember · When a passage shows both a need and a harm, the crucial message usually balances them rather than dropping either.

Read the passage (Passage—3) — this item is based on it

Along with sustainable lifestyles, climate justice is regarded as a significant principle in environmental parlance. Both the principles have bearings on political and economic choices of the nation. So far, in our climate change summits or compacts, both the principles have eluded consensus among nations. Justice, in the judicial sense, is well defined. However, in the context of climate change, it has scientific as well as socio-political connotations. The crucial question in the next few years will be how resources, technologies and regulations are used to support the victims of climate change. Justice in climate is not confined to actions relating to mitigation, but includes the wider notion of support for adaptation to climate change and compensation for loss and damage.

Which one of the following statements best reflects the most logical, rational and crucial message conveyed by the passage?

Answer & explanation

Answer: (a) Climate justice should be ingrained in detail in the rules of all the new climate compacts/agreements.

Climate justice has so far eluded consensus at climate summits, and the crucial question ahead is how resources, technologies and regulations will support victims through mitigation, adaptation and compensation for loss and damage. The message is that climate justice must be built into the rules of future climate agreements.

✓ (a) The principle has 'eluded consensus' in 'summits or compacts', and the passage lists what justice must include (mitigation, adaptation support, compensation). Writing it into new agreements follows.
✗ (b) Uneven distribution of environmental resources is not discussed.
✗ (c) The passage speaks of supporting victims, but not of an impending problem of huge numbers of climate refugees.
✗ (d) Blame on developed countries and burden-sharing are outside the passage.

Remember · When a passage names an unresolved principle and spells out what it must cover, the message is usually to build it into future rules.

Sourcing food from non-agricultural lands (uncultivated systems such as forests, wetlands, pastures, etc) in addition to agricultural lands enables a systemic approach to food consumption. It allows rural and tribal communities to sustain themselves for the whole year and steer clear of natural disasters and season-induced shortfalls of agricultural food. Since the productivity of trees is often more resilient to adverse weather conditions than annual crops, forest foods often provide a safety net during periods of food shortages caused by crop failure; forest foods also make important contributions during seasonal crop production gaps.

Which one of the following statements best reflects the most logical and rational message conveyed by the author of the passage?

Answer & explanation

Answer: (d) Agroecosystems should be developed in addition to or along with conventional agriculture.

The passage recommends sourcing food from forests, wetlands and pastures in addition to farmland, because such foods are resilient and fill gaps when crops fail or between seasons. So these food systems should be developed alongside conventional agriculture, not in place of it.

✗ (a) Replacing other trees with food-yielding trees is not proposed.
✗ (b) 'Cannot be ensured' is too strong; the passage offers a supplement to agriculture, not a verdict against it.
✗ (c) Converting wastelands is not discussed; the passage speaks of existing uncultivated systems such as forests and wetlands.
✓ (d) The key phrase is 'in addition to agricultural lands': uncultivated food systems act as a safety net alongside conventional farming.

Remember · Watch small phrases like 'in addition to': they rule out options that replace rather than supplement.

Read the passage (Passage—2) — this item is based on it

While awareness on use/misuse and abuse of antibiotics is common knowledge, as is the impact of dosing poultry with antibiotics, the environmental impact of antibiotics-manufacturing companies not treating their waste has scarcely been discussed at any length or seriousness thus far. Pollution from antibiotics factories is fuelling the rise of drug-resistant infections. The occurrence of drug-resistant bacteria surrounding the pharma manufacturing plants is well known.

Which one of the following statements best reflects the most logical and practical message conveyed by the passage?

Answer & explanation

Answer: (a) It is necessary to put proper effluent treatment protocols in place.

The passage's new point is that antibiotic factories that do not treat their waste are fuelling drug-resistant infections around their plants. The practical remedy is proper treatment of their effluents.

✓ (a) The problem named is 'companies not treating their waste'; effluent treatment protocols tackle it directly.
✗ (b) Awareness of antibiotic misuse is already 'common knowledge'; the neglected issue is factory waste, not public awareness.
✗ (c) The passage ties resistance to untreated factory pollution, which can be fixed; it does not call the spread inherent or unavoidable.
✗ (d) Moving factories to remote areas would shift the pollution, not treat it.

Remember · For a 'practical message', choose the remedy that targets the exact cause named; relocation or awareness drives miss it.

Read the passage (Passage—3) — this item is based on it

Benefits of good quality school education accrue only when students complete and leave school after having acquired the gateway skills. Like one learns to walk before running, similarly one picks up advanced skills only after picking the basic foundational skills. The advent of the knowledge economy poses new challenges, and one of the severe consequences of having an uneducated workforce will be our inability to keep pace with the global economy. Without a strong learning foundation at the primary level, there can be no improvement in higher education or skill development.

Which one of the following statements best reflects the crux of the passage?

Answer & explanation

Answer: (a) To become a global power, India needs to invest in universal quality education.

Advanced skills rest on foundational learning; without a strong primary base there can be no improvement in higher education or skills, and an uneducated workforce cannot keep pace with the global economy. The crux is that India must invest in quality education for all to compete globally.

✓ (a) Quality schooling that gives every student the 'gateway skills' is presented as the base for keeping pace with the global, knowledge-based economy.
✗ (b) The passage does not say India is unable to become a global power or that it neglects the knowledge economy.
✗ (c) It says the opposite: improvement in higher education and skills depends on a strong primary foundation.
✗ (d) Parents' literacy is not mentioned.

Remember · The crux keeps the passage's own order of priorities; an option that reverses it (higher education before foundations) is wrong.

Read the passage (Passage—1) — this item is based on it

The paradox of choice is illustrated by the story of Buridan's ass. Jean Buridan, the 14th century philosopher, wrote about free will and the inability to choose due to numerous choices and uncertainties. In the story, a donkey stands between two equally appealing stacks of hay. Unable to decide which to eat, it starves to death. Changes in technology and innovations such as smart phones and tablets only exacerbate our glut of choices. Constant connectivity and overconsumption of real-time data and social media can leave little room for self-reflection and rest, making decisions more difficult. Life is about choices. Many people are overwhelmed with attractive life choices, yet find themselves unhappy and anxious.

Which one of the following statements best reflects the most logical message implied by the above passage?

Answer & explanation

Answer: (d) In our lives, having too few choices may not be a good thing, but having too many can be equally as difficult.

Buridan's ass starves between two equally good choices, and modern technology only adds to our glut of choices, leaving people overwhelmed, unhappy and anxious. The implied message is the paradox of choice: too many choices can be as troublesome as too few.

✗ (a) Technology is said to worsen our glut of choices, not to weaken the structure of society.
✗ (b) The passage is about the burden of too many attractive choices, not a life of endless uncertainty and difficulty in general.
✗ (c) Other people's opinions and lack of courage are not discussed.
✓ (d) People 'overwhelmed with attractive life choices, yet ... unhappy and anxious' show that an excess of choice brings its own difficulty — the paradox of choice.

Remember · When a passage opens with a named idea (here, the paradox of choice), the right option usually restates that idea.

Read the passage (Passage—2) — this item is based on it

Household finance in India is unique. We have a tendency to invest heavily in physical assets such as gold and property. Steps to encourage the financialization of savings are critical. A populace accustomed to traditional processes will not simply jump into financialization. Hurdles to change include onerous bureaucracy, a scepticism of organized financial institutions, a lack of basic information about which of the myriad services and providers is best for each family, and how (and even if) one can make the transition between them if necessary.

Regarding the financialization of household savings, which of the following statements best reflect the solutions that are implied by the passage?

1.A flexible environment is needed to develop solutions.
2.Households need customised solutions.
3.Innovations in financial technology are required.

Select the correct answer using the code given below:

Answer & explanation

Answer: (d) 1, 2 and 3

The passage lists the hurdles to financialization: onerous bureaucracy, scepticism of formal institutions, lack of information about which of many services suits each family, and difficulty in switching between them. Each suggested solution answers one of these hurdles, so all three are implied.

✓ 1. 'Onerous bureaucracy' is a named hurdle; a flexible, less rigid environment is the implied answer.
✓ 2. People lack information on which service 'is best for each family', so solutions must be suited to each household.
✓ 3. Financial technology can give easy information, simpler access and smoother switching between providers — the remaining hurdles.

Remember · For implied solutions, match each hurdle the passage lists to a remedy; a remedy that answers a named hurdle is implied.

Read the passage (Passage—3) — this item is based on it

Pharmaceutical patents grant protection to the patentee for the duration of the patent term. The patentees enjoy the liberty to determine the prices of medicines, which is time-limited to the period of monopoly, but could be unaffordable to the public. Such patent protection offered to the patentees is believed to benefit the public over the longer term through innovations and research and development (R&D), although it comes at a cost, in the nature of higher prices for the patented medicine. The patent regime and price protection — through a legally validated high price for the medicine during the currency of the patent — provide the patentee with a legitimate mechanism to get returns on the costs incurred in innovation and research.

Based on the above passage, the following assumptions have been made:

1.Patent protection given to patentees puts a huge burden on public's purchasing power in accessing patented medicines.
2.Dependence on other countries for pharmaceutical products is a huge burden for developing and poor countries.
3.Providing medicines to the public at affordable prices is a key goal during the public health policy design in many countries.
4.Governments need to find an appropriate balance between the rights of patentees and the requirements of the patients.

Which of the above assumptions are valid?

Answer & explanation

Answer: (b) 1 and 4

Patents let firms set high prices that may be unaffordable, justified as a return on innovation that benefits the public later. This assumes a real burden on buyers of patented medicines and a need for governments to balance patentees' rights with patients' needs.

✓ 1. Prices during the monopoly 'could be unaffordable to the public' and the benefit 'comes at a cost ... of higher prices' — a burden on buyers.
✗ 2. Dependence on other countries for medicines is not discussed.
✗ 3. How countries design public health policy is outside the passage, which only describes the patent trade-off.
✓ 4. The patentee's 'legitimate mechanism to get returns' stands against prices the public may not afford; resolving this tension calls for a balance.

Remember · Assumptions come from tensions inside the passage; reject statements about topics (imports, policy design) it never touches.

Read the passage (Passage—4) — this item is based on it

India should ensure the growth of the digital economy while keeping personal data of citizens secure and protected. No one will innovate in a surveillance-oriented environment or in a place where an individual's personal information is compromised. The ultimate control of data must reside with the individuals who generate it; they should be enabled to use, restrict or monetise it as they wish. Therefore, data protection laws should enable the right kind of innovation — one that is user-centric and privacy protecting.

Based on the above passage, the following assumptions have been made:

1.Protection of privacy is not just a right, but it has value to the economy.
2.There is a fundamental link between privacy and innovation.

Which of the above assumptions is/are valid?

Answer & explanation

Answer: (c) Both 1 and 2

The passage ties the protection of personal data to growth of the digital economy and says no one will innovate where personal information is compromised. So privacy has economic value and is closely linked to innovation; both assumptions hold.

✓ 1. India should grow the digital economy 'while keeping personal data ... secure', and individuals may 'monetise' their data — privacy carries economic value.
✓ 2. 'No one will innovate in a surveillance-oriented environment', and laws should enable 'privacy protecting' innovation — a direct link.

Remember · If the argument rests on a chain of links (privacy → innovation → digital economy), each link is a valid assumption.

Read the passage (Passage—1) — this item is based on it

In India, while the unemployment rate is a frequently used measure of poor performance of the economy, under conditions of rising school and college enrolment, it paints an inaccurate picture. The reported unemployment rate is dominated by the experience of younger Indians who face higher employment challenges and exhibit greater willingness to wait for the right job than their older peers. The unemployment challenge is greater for people with secondary or higher education, and rising education levels inflate unemployment challenges.

Which one of the following statements most likely reflects as to what the author of the passage intends to say?

Answer & explanation

Answer: (b) Unemployment must be seen as a function of rising education and aspirations of young Indians.

The author says the unemployment rate misleads when enrolment is rising: educated young Indians wait for the right job, and rising education levels inflate unemployment. So unemployment has to be read against rising education and aspirations, not only as a sign of a weak economy.

✗ (a) The passage says nothing about the quality of education; it only notes rising enrolment.
✓ (b) The rate 'paints an inaccurate picture' because the young 'wait for the right job' and 'rising education levels inflate unemployment challenges' — unemployment tracks education and aspirations.
✗ (c) Labour-intensive industries are not mentioned; this brings in an outside cause.
✗ (d) The passage diagnoses how to read the unemployment rate; it offers no remedy such as redesigning education for self-employment.

Remember · For 'what the author intends to say', pick the option that restates the central claim; reject causes or remedies the passage never mentions.

Read the passage (Passage—2) — this item is based on it

“Science by itself is not enough, there must be a force and discipline outside the sciences to coordinate them and point to a goal. It is not possible to run a course aright when the goal itself has not been rightly placed. What science needs is philosophy — the analysis of scientific method and the coordination of scientific purposes and results; without this, any science must be superficial. Government suffers, precisely like science, for lack of philosophy. Philosophy bears to science the same relationship which statesmanship bears to politics: movement guided by total knowledge and perspective, as against aimless and individual seeking. Just as the pursuit of knowledge becomes scholasticism when divorced from the actual needs of men and life, so the pursuit of politics becomes a destructive bedlam when divorced from science and philosophy.”

Which one of the following statements best reflects the most rational, logical and practical message conveyed by the passage?

Answer & explanation

Answer: (b) It is not desirable to have Governments managed by empirical statesmen unless well mixed with others who are grounded in learning and reflect wisdom.

The passage says government, like science, suffers for lack of philosophy, and that politics divorced from science and philosophy becomes a 'destructive bedlam'. The practical lesson is that government should not be left to merely empirical statesmen; they must work alongside people grounded in learning and wisdom.

✗ (a) Tempting, but the passage does not ask every statesman to be trained in scientific method; it asks that politics be guided by knowledge and perspective — a narrower, less practical prescription.
✓ (b) 'Government suffers ... for lack of philosophy' and politics becomes 'bedlam when divorced from science and philosophy' — so rule by the merely empirical needs the balance of the learned and wise.
✗ (c) An education system training all citizens from an early age goes far beyond anything the passage discusses.
✗ (d) 'All scientists' must be philosophers is extreme; the passage wants philosophy as a coordinating discipline 'outside the sciences', and its real concern is government.

Remember · When asked for the 'most practical' message, prefer the moderate, workable conclusion; drop options that demand training for everyone or use 'all'.

Read the passage (Passage—3) — this item is based on it

“The last end of the state is not to dominate men, nor to restrain them by fear; rather it is so to free each man from fear that he may live and act with full security and without injury to himself or his neighbour. The end of the state, I repeat, is not to make rational beings into brute beasts and machines. It is to enable their bodies and their minds to function safely. It is to lead men to live by, and to exercise, a free reason; that they may not waste their strength in hatred, anger and guile, nor act unfairly toward one another.”

Based on the above passage, which one of the following terms best expresses the ultimate goal of the state?

Answer & explanation

Answer: (d) Liberty

The passage says the end of the state is to free each man from fear, to let bodies and minds function safely, and to lead men to exercise a free reason. Every one of these aims is a form of freedom, so liberty is the term that covers them all.

✗ (a) Security 'without injury' is part of the aim, but it serves the larger end of freeing each man from fear — too narrow.
✗ (b) Bodies and minds functioning 'safely' is a means; the passage never names health as the end.
✗ (c) Not acting 'unfairly toward one another' is a result of free reason, not the ultimate goal.
✓ (d) 'To free each man from fear', to 'live by, and to exercise, a free reason' — the state's end is liberty.

Remember · For 'ultimate goal' questions, choose the single term that covers every aim the passage lists; partial aims are traps.
