    Natural selection cannot anticipate future environments on the
    earth. Therefore, the set of existing organisms can never be fully
    prepared for environmental catastrophes that await life. An outcome of
    this is the extinction of those species which cannot overcome
    environmental adversity. This failure to survive, in modem terms, can be
    attributed to the genomes which are unable to withstand geological.
    vagaries or biological mishaps (infections, diseases and so on). In
    biological evolution on 'the earth, extinction of species has been a
    major feature. The earth may presently have up to ten million species,
    yet more than 90% of species that have ever lived on the earth are now
    extinct. Once again, the creationist doctrines fail to satisfactorily
    address why a divine creator will firstly bother to create millions of
    species and then allow them to perish: The Darwinian explanation for
    extinct life is once again simple, elegant and at once
    convincing-organisms go extinct as a function of environmental or
    biological assaults for which their inheritance deems them ill-equipped.
    Therefore, the so-called Darwinian theory of evolution is not a theory
    at all. Evolution happens-this is a fact. The mechanism of evolution
    (Darwin proposed natural selection) is amply supported by scientific
    data. Indeed, to date no single zoological, botanical, geological,
    pale-ontological, genetic or physical evidence has refuted either of the
    central two main Darwinian ideas. If religion is not taken into
    consideration, Darwinian Jaws are acceptable just like the laws proposed
    by Copernicus, Galileo, Newton and Einstein-sets of natural laws that
    explain natural phenomena in the universe.
    According to the passage, natural selection cannot anticipate -
    future environments on the earth as:

    1. species not fully prepared to -face the environmental changes that await them will face extinction.
    2. all the existing species would get extinct as their genomes will not withstand biological mishaps.
    3. inability of the genome to withstand environmental changes would - result in extinction.
    4. extinction of species is a common feature.

    In some places in the world the productivity of staples such as rice and wheat has reached a plateau. Neither new Strains nor fancy agrochemicals are raising the yields. Nor is there much unfarmed land left that is suitable to be bought under the plough. If global temperature continues to rise, some places will become unsuitable for farming. Application of-technology can 'help overcome these problems. Agricultural technology is changing fast. Much of this change is brought about by affluent farmers in the West Americas. Techniques developed in the West are being adapted in some places to make tropical crops more productive. Technology is of little use if it is not adapted. In the developing world, that applies as much to existing farming techniques as it does to the latest advances in genetic modification. Extending to the small holders and subsistence farmers of Africa and Asia the best of today's. agricultural practices, in such simple matters as how much fertilizers to apply and when, would lead to a greatly increased availability of food for humanity. So would things like better roads and storage facilities, to allow for the carriage of-surpluses to markets and reduce wastage.

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

    1. Poor countries need to bring about change in their existing farming techniques.
    2. Developed countries have better infrastructure and they waste less food.

    Which of the above assumptions is/are valid?

    A social and physical environment riddled with poverty, inequities, unhygienic and insanitary conditions generates the risk of infectious diseases, Hygiene has different levels : Personal, domestic and community hygiene. There is no doubt that personal cleanliness brings down the rate of infectious diseases. But the entry of the market into this domain has Created a false sense of security that gets Conditioned and reinforced by the onslaught of advertisements. Experience in Western Europe Shows that along with personal hygiene, general improvements in environmental conditions and components like clean water, sanitation and food security have brought down infant/child death/infection rates considerably. The obsession with hand hygiene also brings in the persisting influence of the market on personal health, overriding or marginalising the negative impact on ecology and the emergence of resistant germs.

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

    1. People who are obsessed with personal hygiene tend to ignore the community hygiene.
    2. Emergence of multi-drug resistant germs can be prevented by personal cleanliness.
    3. Entry of the market in the domain of hygiene increases the risk of infectious diseases.
    4. Scientific and micro-level, interventions are not sufficient to bring down the burden of infectious diseases.
    5. It is community hygiene implemented through public - health measures that is really effective in the battle against infectious diseases.

    In the immediate future, we will see the increasing commodification of many new technologies-artificial intelligence and robotics, 3D manufacturing, custom made biological and pharmaceutical products, lethal autonomous weapons and driverless cars. This will pose conundrums. The moral question of how a driverless car will decide between hitting jaywalker and swerving and damaging the car has often been debated. The answer is both simple save the human life and complex. At which angle should the car swerve just enough to save the jaywalker or more than enough? If the driverless car is in Dublin, who would take the decision? The Irish Government, or the car’s original code writer in California, or a software programmer in Hyderabad to whom maintenance is outsourced? If different national jurisdictions have different fine print on prioritizing a human life, how will it affect insurance and investment decisions, including transnational ones?

    Which of the following statements best reflect the rational, plausible, and practical implications that can be derived from the passage given above?

    1. Too much globalization is not in the best interests of any country.
    2. Modern technologies are increasingly blurring the economic borders.
    3. Innovation and capital have impinged on the domain of the state.
    4. Public policy of every country should focus on developing its own supply chains.
    5. Geopolitics will have to reconcile to many ambiguities and uncertainties.

    Although most of the Genetically Modified (GM) crops cultivated now are genetically engineered for a single trait, in future, crops genetically engineered for more than one trait will be the norm. Thus, biotechnology's role in agriculture and the regulation of the same cannot be understood solely in the context of the current generation of GM crops. Instead, there is a need to take a comprehensive look, taking into account various aspects, including socio-economic impacts, so that the potential of the technology can be harnessed while minimizing negative impacts. Given the importance of biotechnology in developing varieties that can help in climate change mitigation and adaptation, not using biotechnology as a part of the climate change action plan; Domestic regulation of biotechnology cannot be viewed in isolation of trade policy and obligations under various international treaties and conventions.

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

    1. Biotechnology regulation is an evolving process.
    2. Participation of people is needed in policy decisions regarding biotechnology regulation;
    3. Biotechnology regulation should take into account socio economic aspects in decision-making.
    4. Wider involvement of political executive in biotechnology regulation improves its effectiveness in dealing with the country's trade policies and international obligations.

    The pulse variety 'Pusa Arhar 16' has the potential to be grown in the paddy-growing regions of Punjab, Haryana and Uttar Pradesh and eventually in all of India. Its yield (about 2000 .kg/hectare) will be significantly greater than those of the existing varieties and because its size will be uniform, it will be amenable to mechanical harvesting, an attractive feature for farmers in northern. India who currently use this technology for paddy. Most important, Arhar straw, unlike paddy straw, is green and can be ploughed back into the soil. In paddy straw, the problem is the high silica content, which does not allow for easy decomposition. In the case of Arhar, the farmer, even after combine harvesting, just needs to run a rotovator to cut the leftover straw into pieces, which can be ploughed back and will decompose very fast. All this is difficult with leftover paddy stalks that cannot be easily salvaged or ploughed back. Farmers, therefore, choose the easiest option of simply burning it.

    Which of the following are the most rational inferences that can be made from the passage?

    1. Farmers' income will be higher with pulse cultivation than with paddy cultivation.
    2. Pulse cultivation causes less pollution as compared to paddy cultivation.
    3. Pulse straw can be used to improve soil quality.
    4. In the context of northern Indian agriculture, paddy straw has no usefulness.
    5. Mechanized agriculture is the main cause for stubble burning.

    In India, agriculture still engages about half of its workforce, and about 85 percent of its farms are small and marginal. Compared to China and Vietnam, which have experienced fast structural and rural transformation, India's story is of slow transformation. As a result, poverty reduction in India was at a much slower pace during 1988-2014, compared to China and Vietnam. India's poverty reduction was slow during 1988-2005, but during 2005-2012, it accelerated dramatically—almost three times faster than during the earlier period. What did India do during this period? Research reveals that the relative price scenario changed significantly (by more than 50%) in favour of agriculture in the wake of rising global prices. This boosted private investments in agriculture by more than 50%. As a result, agri-GDP growth touched 4.1% during 2007-20 12 as against 2.4% during 2002-2007. The net surplus of agri-trade touched $25 billion in 2013-2014; real farm wages rose 6y 7% per annum. All this led to unprecedented fall in poverty.

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

    1. Structural and rural transformation is impossible when farms are mainly small and marginal.
    2. A good price incentive can trigger investments in agriculture.
    3. India needs to build value chains for high-value agriproducts like livestock and horticulture.
    4. Higher global prices of agricultural commodities are essential for India's poverty reduction.

    Food varieties extinction is happening all over the world — and its happening fast. For example, of the 7,000 apple varieties that were grown during the nineteenth century. fewer than a hundred remain. In the Philippines, thousands of varieties of rice once thrived now only up to a hundred are grown there. In China, 90 percent of the wheat varieties cultivated just a century ago have disappeared. Farmers in the past painstakingly bred and developed crops well suited to the peculiarities of their local climate and environment. In the recent past; our heavy dependence on a few high yielding varieties and technology-driven production and distribution of food is causing the dwindling of diversity in food crops. If some mutating crop disease or future climate change decimates the few crop plants we have come to depend onto feed our growing population, we might desperately need some of those varieties we have let go extinct.

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

    1. 'Humans have been the main reason for the large scale extinction of plant species.
    2. Consumption of food mainly from locally cultivated crops ensures crop diversity.
    3. The present style of production and distribution of food will finally lead to the problem of food scarcity in the near future.
    4. Our food security may depend on our ability to preserve the locally cultivated varieties, of crops.

    Which of the above assumptions are valid?
