UPSC Critical Reading

We are witnessing a dangerous dwindling of biodiversity in our food supply. The green revolution is a mixed blessing. Over time farmers have come to rely heavily on broadly adapted, high yield crops to the exclusion of varieties adapted to the local conditions. Monocropping vast fields with the same genetically uniform seeds helps boost yield and meet immediate hunger needs. Yet high-yield varieties are also genetically weaker crops that require expensive chemical fertilizers and toxic pesticides. In our focus on increasing the amount of food we produce today, we have accidentally put ourselves at risk for food shortages in future.

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

  1. In our agricultural practices, we have become heavily dependent on expensive chemical fertilizers and toxic pesticides only due to green revolution
  2. Monocropping vast fields with high-yield varieties is possible due to green revolution
  3. Monocropping with high-yield varieties is the only way to ensure food security to millions
  4. Green revolution can pose a threat to biodiversity in food supply and food security in the long run

UPSC Critical Reading

We generally talk about democracy but when it comes to any particular thing, we prefer a belonging to our caste or community or religion. So long as we have this kind of temptation, our democracy will remain a phoney kind of democracy. We must be in a position to respect a man as a man and to extend opportunities for development to those who deserve them and not to those who happen to belong to our community or race. This fact of favouritism has been responsible for much discontent and ill-will in our country.

Which one of the following statements best sums up the above passage?

  1. True democracy could be established by providing equal opportunities to all
  2. It will never be possible for us to establish truly democratic governance in our country
  3. Our country has a lot of diversity with its many castes, communities and religions
  4. So far none of us have actually understood the meaning of democracy

UPSC Critical Reading

Governments may have to take steps which would otherwise be an infringement on the Fundamental Rights of individuals, such as acquiring a person's land against his will, or refusing permission for putting up a building, but the larger public interest for which these are done must be authorized by the people (Parliament). Discretionary powers to the administration can be done away with. It is becoming more and more difficult to keep this power within limits as the government has many number of tasks to perform. Where discretion has to be used, there must be rules and safeguards to prevent misuse of that power. Systems have to be devised which minimise, if not prevent, the abuse of discretionary power. Government work must be conducted within a framework of recognised rules and principles, and decisions should be similar and predictable.

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

  1. Government should always be given wide discretionary power in all matters of administration
  2. The supremacy of rules and safeguards should prevail as opposed to the influence of exclusive discretion of authority
  3. Parliamentary democracy is possible only if the Government has wider discretionary power
  4. None of the above statements is a logical assumption that can be made from this passage

UPSC Critical Reading

No Right is absolute, exclusive or inviolable. The Right of personal property, similarly, has to be perceived in the larger context of its assumed legitimacy. The Right of personal property should unite the principle of liberty with that of equality, and both with the principle of cooperation.

In the light of the argument in the above passage, which one of the following statements is the most convincing explanation?

  1. Personal property is a theft and an instrument of exploitation. The Right of personal property is therefore violative of economic justice.
  2. The Right of personal property is a Natural Right duly supported by statutes and scriptures.
  3. The comprehensive idea of economic justice demands that the Right of each person to acquisition of property has to be reconciled with that of others.
  4. The Right of personal property is violative of distributive justice and negates the principle of cooperation.

UPSC Critical Reading

Open defecation is disastrous when practised in very densely populated areas, where it is impossible to keep away human faeces from crops, wells, food and children's hands. Groundwater is also contaminated by open defecation. Many ingested germs and worms spread diseases. They prevent the body from absorbing calories and nutrients. Nearly one-half of India's children remain malnourished. Lakhs of them die from preventable conditions. Diarrhoea leaves Indian's bodies smaller on average than those of people in some poorer countries where people eat fewer calories. Underweight mothers produce stunted babies prone to sickness who may fail to develop their full cognitive potential. The germs released into environment harm rich and poor alike, even those who use latrines.

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

  1. Open defecation reduces the human capital of India's workforce
  2. Open defecation is the most important public health problem of India
  3. The Central and State governments in India do not have enough resources to afford a latrine for each household
  4. Open defecation is a public health problem in all developing countries

UPSC Critical Reading

The conflict between man and State is as old as State history. Although attempts have been made for centuries to bring about a proper adjustment between the competing claims of State and the individual, the solution seems to be still far off. This is primarily because of the dynamic nature of human society where old values and ideas constantly yield place to new ones. It is obvious that if individuals are allowed to have absolute freedom of speech and action, the result would be chaos, ruin and anarchy.

The author's viewpoint can be best summed up in which of the following statements?

  1. Old values, ideas and traditions persist despite the dynamic nature of human society.
  2. Constitutional guarantee of freedom of speech is not in the interest of society.
  3. The conflict between the claims of State and individual remains unresolved.
  4. Anarchy and chaos are the obvious results of democratic traditions.

Climate change is already making many people hungry all over the world, by disrupting crop yields and pushing up prices. And it is not just food but nutrients that are becoming scarcer as the climate changes. It is the poorest communities that will suffer the worst effects of climate change, including increased hunger and malnutrition as crop production and livelihoods are threatened. On the other hand, poverty is a driver of climate change, as desperate communities resort to unsustainable use of resources to meet current needs.

Which among the following is the most logical corollary to the above passage?

  1. All the countries of the world must unite in fighting poverty and malnutrition and treat poverty as a global problem
  2. We must stop unsustainable agricultural practices immediately and control food prices
  3. Poverty and climate impacts reinforce each other and therefore we have to re-imagine our food systems
  4. Government should allocated more funds to poverty alleviation programmes and increase food subsidies to the poor communities

UPSC Critical Reading

The richer States have a responsibility to cut down carbon emissions and promote clean energy investments. These are the States that got electricity, grew faster and now have high per capita income, making them capable of sharing India's burden of becoming eco-friendly. Delhi, for example, can help by generating its own clean electricity using solar rooftop panels or even help poor States finance their clean energy projects. It is no secret that State Electricity Boards, which control 95% of the distribution network, are neck-deep in losses. These losses further discourage State utilities from adopting renewable energy as it is more expensive than fossil fuels.

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

  1. The poor States always have to depend on rich States for electricity.
  2. The richer States must lead in the production and adoption of renewable energy.
  3. The high economic disparity between the rich and poor States is the major cause of high carbon emissions in India.
  4. The State Electricity Boards can improve their finances by undertaking clean energy projects.
