Passage – 3
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 Indians’ 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.

The existence / establishment of formal financial institutions that offer safe, reliable and alternative financial instruments is fundamental in mobilising savings.

Savings help poor households manage volatility in cash flow, smoothen consumption, and build working capital. Poor households without access to a formal savings mechanism encourage immediate spending temptations.
65. With reference to the above passage, consider the following statements:
1. Indian financial institutions do not offer any financial instruments to rural households to mobilise their savings.

Passage – 6
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.
67. Which among the following is the most logical assumption that can be made from the above passage?
(a) Government should always be given wide discretionary power in all matters of administration.
(b) The supremacy of rules and safeguards should prevail as opposed to the influence of exclusive discretion of authority.
(c) Parliamentary democracy is possible only if the Government has wider discretionary power.
(d) None of the above statements is a logical assumption that can be made from this passage.
