Q1
Reading ComprehensionReading ComprehensionInference
PASSAGE

What climate change will undeniably do is cause or amplify events that hasten the reduction of resources. Competition over these diminishing resources would ensue in the form of political or even violent conflict. Resource-based conflicts have rarely been overt and are thus difficult to isolate. Instead, they take on veneers that appear more politically palatable. Conflicts over resources like water are often cloaked in the guise of identity or ideology.

What does the above passage imply?

AResource-based conflicts are always politically motivated.
BThere are no political solutions to resolve environmental and resource-based conflicts.
CEnvironmental issues contribute to resource stresses and political conflict.
DPolitical conflict based on identity or ideology cannot be resolved.
Show answer & explanation
ANSWERC
EXPLANATION

Climate change can intensify resource scarcity; competition over scarce resources can then produce political or violent conflict.

Q2
Reading ComprehensionReading ComprehensionMain Idea / Central Theme
PASSAGE

The man who is perpetually hesitating which of the two things he will do first, will do neither. The man who resolves, but suffers his resolution to be changed by the first counter-suggestion of a friend—who fluctuates from opinion to opinion and veers from plan to plan—can never accomplish anything. He will at best be stationary and probably retrograde in all. It is only the man who first consults wisely, then resolves firmly and then executes his purpose with inflexible perseverance, undismayed by those petty difficulties which daunt a weaker spirit—that can advance to eminence in any line.

The keynote that seems to be emerging from the passage is that

Awe should first consult wisely and then resolve firmly
Bwe should reject suggestions of friends and remain unchanged
Cwe should always remain broad-minded
Dwe should be resolute and achievement-oriented
Show answer & explanation
ANSWERA
EXPLANATION

The passage stresses wise consultation followed by firm resolution and persistent execution.

In the last three decades, the extent of summer ice has declined by about 30 per cent. The lengthening period of summer melt threatens to undermine the whole Arctic food web, atop which stand polar bears.

Which among the following is the most crucial message conveyed by the above passage?

AClimate change has caused Arctic summer to be short but temperature to be high.
BPolar bears can be shifted to South Pole to ensure their survival.
CWithout the presence of polar bears, the food chains in Arctic region will disappear.
DClimate change poses a threat to the survival of polar bears.
Show answer & explanation

Earlier and faster melting and later freezing threaten the Arctic food web, including polar bears at its top.

Q4
Reading ComprehensionReading ComprehensionMain Idea / Central Theme
PASSAGE

Why do people prefer open defecation and not want toilets or, if they have them, only use them sometimes? Recent research has shown two critical elements: ideas of purity and pollution, and not wanting pits or septic tanks to fill because they have to be emptied. These are the issues that nobody wants to talk about, but if we want to eradicate the practice of open defecation, they have to be confronted and dealt properly.

Which among the following is the most crucial message conveyed by the above passage?

AThe ideas of purity and pollution are so deep-rooted that they cannot be removed from the minds of the people.
BPeople have to perceive toilet use and pit-emptying as clean and not polluting.
CPeople cannot change their old habits.
DPeople have neither civic sense nor sense of privacy.
Show answer & explanation
ANSWERB
EXPLANATION

The passage identifies purity/pollution perceptions and pit-emptying concerns as barriers that must be confronted to eradicate open defecation.

Q5
Reading ComprehensionReading ComprehensionInference
PASSAGE

In the last two decades, the world's gross domestic product (GDP) has increased by 50 per cent, whereas inclusive wealth has increased by a mere 6 per cent. In recent decades, GDP-driven economic performance has only harmed inclusive wealth like human capital; and natural capital like forests, land and water. While the world's human capital which stands at 57 per cent of total inclusive wealth grew by only 8 per cent, the natural capital which is 23 per cent of total inclusive wealth declined by 30 per cent worldwide in the last two decades.

Which of the following is the most crucial inference from the above passage?

AMore emphasis should be laid on the development of natural capital.
BThe growth driven by GDP only is neither desirable nor sustainable.
CThe economic performance of the countries of the world is not satisfactory.
DThe world needs more human capital under the present circumstances.
Show answer & explanation
ANSWERB
EXPLANATION

GDP grew much faster than inclusive wealth, while human and natural capital suffered; the passage therefore questions GDP-only growth.

Q6
Reading ComprehensionReading ComprehensionInference
PASSAGE

By 2020, when the global economy is expected to run short of 56 million young people, India, with its youth surplus of 47 million, could fill the gap. It is in this context that labour reforms are often cited as the way to unlock double-digit growth in India. In 2014, India's labour force was estimated to be about 40 per cent of the population, but 93 per cent of this force was in unorganized sector. Over the last decade, the compound annual growth rate (CAGR) of employment has slowed to 0.5 per cent, with about 14 million jobs created during last year when the labour force increased by about 15 million.

Which of the following is the most rational inference from the above passage?

AIndia must control its population growth so as to reduce its unemployment rate.
BLabour reforms are required in India to make optimum use of its vast labour force productively.
CIndia is poised to achieve the double-digit growth very soon.
DIndia is capable of supplying skilled young people to other countries.
Show answer & explanation
ANSWERB
EXPLANATION

The passage links India's large youth surplus and weak employment growth to the need for labour reforms that improve productive use of labour.

Q7
Reading ComprehensionReading ComprehensionMain Idea / Central Theme
PASSAGE

The very first lesson that should be taught to us when we are old enough to understand it, is that complete freedom from the obligation to work is unnatural, and ought to be illegal, as we can escape our share of the burden of work only by throwing it on someone else's shoulders. Nature ordains that the human race shall perish of famine if it stops working. We cannot escape from this tyranny. The question we have to settle is how much leisure we can afford to allow ourselves.

The main idea of the passage is that

Ait is essential for human beings to work
Bthere should be a balance between work and leisure
Cworking is a tyranny which we have to face
Dhuman's understanding of the nature of work is essential
Show answer & explanation
ANSWERA
EXPLANATION

The passage treats work as an unavoidable human necessity and asks only how much leisure can be afforded.

PASSAGE

There is no harm in cultivating habits so long as they are not injurious. Indeed, most of us are little more than bundle of habits. Take away our habits and the residuum would hardly be worth bothering about. We could not get on without them. They simplify the mechanism of life. They enable us to do a multitude of things automatically, which, if we had to give fresh and original thought to them each time, would make existence an impossible confusion.

The author suggests that habits

Atend to make our lives difficult
Badd precision to our lives
Cmake it easier for us to live
Dtend to mechanize our lives
Show answer & explanation
ANSWERC
EXPLANATION

Habits simplify life by allowing many actions to be performed automatically.

Q26
Reading ComprehensionReading ComprehensionAssumption
PASSAGE

The greatest blessing that technological progress has in store for mankind is not, of course, an accumulation of material possessions. The amount of these that can be effectively enjoyed by one individual in one lifetime is not great. But there is not the same narrow limit to the possibilities of the enjoyment of leisure. The gift of leisure may be abused by people who have had no experience of making use of it. Yet the creative use of leisure by a minority in societies has been the mainspring of all human progress beyond the primitive level.

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

1. People always see the leisure time as a gift and use it for acquiring more material possessions.

2. Use of leisure by some people to produce new and original things has been the chief source of human progress.

Which of these assumptions is/are valid?

A1 only
B2 only
CBoth 1 and 2
DNeither 1 nor 2

Q27
Reading ComprehensionReading ComprehensionAssumption
PASSAGE

There is more than a modicum of truth in the assertion that “a working knowledge of ancient history is necessary to the intelligent interpretation of current events”. But the sage who uttered these words of wisdom might well have added something on the benefits of studying particularly the famous battles of history for the lessons they contain for those of us who lead or aspire to leadership. Such a study will reveal certain qualities and attributes which enabled the winners to win—and certain deficiencies which caused the losers to lose. And the student will see that the same pattern recurs consistently, again and again, throughout the centuries.

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

1. A study of the famous battles in history would help us understand the modern warfare.

2. Studying the history is essential for anyone who aspires to be a leader.

Which of these assumptions is/are valid?

A1 only
B2 only
CBoth 1 and 2
DNeither 1 nor 2

There has been a significant trend worldwide towards regionalism in government, resulting in a widespread transfer of powers downwards towards regions and communities since 1990s. This process, which involves the creation of new political entities and bodies at a sub-national level and an increase in their content and powers, is known as devolution. Devolution has been characterized as being made up of three factors—political legitimacy, decentralization of authority and decentralization of resources. Political legitimacy here means a mass demand from below for the decentralization process, which is able to create a political force for it to take place. In many cases, decentralization is initiated by the upper tier of government without sufficient political mobilization for it at the grassroots level, and in such cases the decentralization process often does not fulfil its objectives.

Which among the following is the most logical, rational and critical inference that can be made from the above passage?

AEmergence of powerful mass leaders is essential to create sub-national political entities and thus ensure successful devolution and decentralization.
BThe upper tier of government should impose devolution and decentralization on the regional communities by law or otherwise.
CDevolution, to be successful, requires a democracy in which there is free expression of the will of the people at lower level and their active participation at the grassroots level.
DFor devolution to take place, a strong feeling of regionalism in the masses is essential.

We live in digital times. The digital is not just something we use strategically and specifically to do a few tasks. Our very perception of who we are, how we connect to the world around us, and the ways in which we define our domains of life, labour and language are hugely structured by the digital technologies. The digital is everywhere and, like air, invisible. We live within digital systems, we live with intimate gadgets, we interact through digital media, and the very presence and imagination of the digital has dramatically restructured our lives. The digital, far from being a tool, is a condition and context that defines the shapes and boundaries of our understanding of the self, the society, and the structure of governance.

Which among the following is the most logical and essential message conveyed by the above passage?

AAll problems of governance can be solved by using digital technologies.
BSpeaking of digital technologies is speaking of our life and living.

The IMF has pointed out that the fast growing economies of Asia face the risk of falling into ‘middle-income trap’. It means that average incomes in these countries, which till now have been growing rapidly, will stop growing beyond a point—a point that is well short of incomes in the developed West. The IMF identifies a number of causes of middle-income trap—none of which is surprising—from infrastructure to weak institutions, to less than favourable macroeconomic conditions. But the broad, overall cause, says IMF, is a collapse in the growth of productivity.

Which among the following is the most logical, rational and critical inference that can be made from the above passage?

AOnce a country reaches middle-income stage, it runs the risk of falling productivity which leads to stagnant incomes.
BFalling into middle-income trap is a general characteristic of fast growing economies.
CThere is no hope at all for emerging Asian economies to sustain the growth momentum.
DAs regards growth of productivity, the performance of Asian economies is not satisfactory.

An innovative India will be inclusive as well as technologically advanced, improving the lives of all Indians. Innovation and R&D can mitigate increases in social inequality and relieve the pressures created by rapid urbanization. The growing divergence in productivity between agriculture and knowledge-intensive manufacturing and services threatens to increase income inequality. By encouraging India’s R&D labs and universities to focus on the needs of poor people and by improving the ability of informal firms to absorb knowledge, an innovation and research agenda can counter this effect. Inclusive innovation can lower the costs of goods and services and create income-earning opportunities for the poor people.

Which among the following is the most logical and rational assumption that can be made from the above passage?

AInnovation and R&D is the only way to reduce rural to urban migration.
BEvery rapidly growing country needs to minimize the divergence between productivity in agriculture and other sectors.

Climate change is likely to expose a large number of people to increasing environmental risks forcing them to migrate. The international community is yet to recognize this new category of migrants. There is no consensus on the definition and status of climate refugees owing to the distinct meaning the term refugees carry under international laws. There are still gaps in understanding how climate change will work as the root cause of migration. Even if there is recognition of climate refugees, who is going to provide protection? More emphasis has been given to international migration due to climate change. But there is a need to recognize the migration of such people within the countries also so that their problems can be addressed properly.

Which of the following is the most rational inference from the above passage?

AThe world will not be able to cope with large scale migration of climate refugees.

Many farmers use synthetic pesticides to kill infesting insects. The consumption of pesticides in some of the developed countries is touching 3000 grams/hectare. Unfortunately, there are reports that these compounds possess inherent toxicities that endanger the health of the farm operators, consumers and the environment. Synthetic pesticides are generally persistent in environment. Entering in food chain they destroy the microbial diversity and cause ecological imbalance. Their indiscriminate use has resulted in development of resistance among insects to insecticides, upsetting of balance in nature and resurgence of treated populations. Natural pest control using the botanical pesticides is safer to the user and the environment because they break down into harmless compounds within hours or days in the presence of sunlight. Plants with pesticidal properties have been in nature for millions of years without any ill or adverse effects on the ecosystem. They are easily decomposed by many microbes common in most soils. They help in the maintenance of biological diversity, of predators and the reduction of environmental contamination and human health hazards. Botanical pesticides formulated from plants are biodegradable and their use in crop protection is a practical sustainable alternative.

On the basis of the above passage, the following assumptions have been made:

1. Synthetic pesticides should never be used in modern agriculture.

2. One of the aims of sustainable agriculture is to ensure minimal ecological imbalance.

An air quality index (AQI) is a way to combine measurements of multiple air pollutants into a single number or rating. This index is ideally kept constantly updated and available in different places. The AQI is most useful when lots of pollution data are being gathered and when pollution levels are normally, but not always, low. In such cases, if pollution levels spike for a few days, the public can quickly take preventive action (like staying indoors) in response to an air quality warning. Unfortunately, that is not urban India. Pollution levels in many large Indian cities are so high that they remain well above any health or regulatory standard for large part of the year. If our index stays in the ‘Red/Dangerous’ region day after day, there is not much any one can do, other than getting used to ignoring it.

Which among the following is the most logical and rational inference that can be made from the above passage?

AOur governments are not responsible enough to keep our cities pollution free.
BThere is absolutely no need for air quality indices in our country.
CAir quality index is not helpful to the residents of many of our large cities.
DIn every city, public awareness about pollution problems should increase.

Productive jobs are vital for growth and a good job is the best form of inclusion. More than half of our population depends on agriculture, but the experience of other countries suggests that the number of people dependent on agriculture will have to shrink if per capita incomes in agriculture are to go up substantially. While industry is creating jobs, too many such jobs are low-productivity non-contractual jobs in the unorganized sector, offering low incomes, little protection, and no benefits. Service jobs are relatively of high productivity, but employment growth in services has been slow in recent years.

Which among the following is the most logical and rational inference that can be made from the above passage?

AWe must create conditions for the faster growth of highly productive service jobs to ensure employment growth and inclusion.
BWe must shift the farm workers to the highly productive manufacturing and service sectors to ensure the economic growth and inclusion.
CWe must create conditions for the faster growth of productive jobs outside of agriculture even while improving the productivity of agriculture.
DWe must emphasize the cultivation of high-yielding hybrid varieties and genetically modified crops to increase the per capita income in agriculture.

A landscape-scale approach to land use can encourage greater biodiversity outside protected areas. During hurricane ‘Mitch’ in 1998, farms using eco-agricultural practices suffered 58 per cent, 70 per cent and 99 per cent less damage in Honduras, Nicaragua and Guatemala, respectively, than farms using conventional techniques. In Costa Rica, vegetative windbreaks and fencerows boosted farmers’ income from pasture and coffee while also increasing bird diversity. Bee pollination is more effective when agricultural fields are closer to natural or seminatural habitat, a finding that matters because 87 per cent of the world’s 107 leading crops depend on animal pollinators. In Costa Rica, Nicaragua and Colombia silvopastoral systems that integrate trees with pastureland are improving the sustainability of cattle production, and diversifying and increasing farmers’ income.

Which among the following is the most logical and rational inference that can be made from the above passage?

AAgricultural practices that enhance biodiversity can often increase farm output and reduce the vulnerability to disasters.
BAll the countries of the world should be encouraged to replace ecoagriculture with conventional agriculture.
CEcoagriculture should be permitted in protected areas without destroying the biodiversity there.

The medium term challenge for Indian manufacturing is to move from lower to higher tech sectors, from lower to higher value-added sectors, and from lower to higher productivity sectors. Medium tech industries are primarily capital intensive and resource processing; and high tech industries are mainly capital and technology intensive. In order to push the share of manufacturing in overall GDP to the projected 25 per cent, Indian manufacturing needs to capture the global market in sectors showing a rising trend in demand. These sectors are largely high technology and capital intensive.

Which among the following is the most logical and rational inference that can be made from the above passage?

AIndia’s GDP displays high value-added and high productivity levels in medium tech and resource processing industries.
BPromotion of capital and technology intensive manufacturing is not possible in India.
