Directions (Q. 4-8) Below is given a passage followed by several possible inferences which can drawn from the facts stated in the passage. You have to examine each inference separately in the context of the passage and decide upon its degree of truth or falsity.

Give answer:

a) If the inference is ‘definitely true’ i.e. it properly from the statement of facts given.

b) If the inference is ‘probably true’ through not ‘definitely true’ in the light of the facts given.

c) If the ‘data are inadequate’, i.e. from the facts given you cannot say whether the inference is likely to be true or false.

d) If the inference is ‘probably false’, though not ‘definitely false’ in the light of the facts given.

e) If the inference is ‘definitely false’, i.e. it cannot possibly be drawn from the facts given or it contradicts the given facts.

Between 2002-03 and 2006-2007, Indian economy grew annualy at 8.7%

led by the services sector at 9% per year. In 1990, India’s share of services, at 40%

of GDP was consistent with its per capita income for low-income country. By 2001 its share of one-half of the GDP was higher by five percentage points, compared to the average for low-income countries. Economic reforms that energized the private corporate sector and technological changes that opened up new vistas in telecommunications, IT and outsourcing are believed to be responsible for th e impressive performance. However, the services led growth remains a puzzle at a low per capita income, with 55% of the work force still engaged in agriculture, and when agriculture decelerated and industry stagnated-3 defying a styled fact in economics.

4. India has now emerged as a high per capita income country.

5. Growth in India’s services sector post 2005 is more than 9%.

6. Less than half of total workforce is engaged in Agricultural sector in India.

7. Share of services sector in India’s GDP has crossed the half way mark in early 2000.

8. In early minutes, the share of services sector in GDP for low per capita income group of countries is about 40%

Directions (Q. 9-13) below are given a passage followed by several possible inferences which can be drawn from the facts stated in the passage. You have to examine each in ference separately in the context of the passage and decide upon its degree of truth or falsity.

Give answer:

a) If the inference is “definitely true” i.e. it properly follows from the statements of facts given.

b) If the inference is “probably true” thuogh not “definitely true” in the light of the facts given.

c) If the data are inadequate i.e. from the facts given you can not say whether the inference is likely to be true or false.

d) If the inference is “probably false” though not “definitely false” in the light of the facts given.

e) If the inference is “definitely false” i.e. it cannot possibly be drawn from the facts given or it contradicts the given facts.

A recent report that satellite data shws groundwater levels in northern India depleting by as much as a foot per year, over the past decade, is a matter of concern.

The clear writing on the wall is that India faces a turbulent water future and veritable crisis without proactive policy and sustainable practices. Besides, the poor monsoon this season and the resultant drought situation pan-India, calls series of glaring anomalies do need to be addressed. For one, there’s far too much reliance on groundwater. For another, out water infrastructure for storage and supply is sorely inadequate. Worse, policy distortions in artificially under pricing key agri-inputs like power have perversely incentivised cultivation of water intensive crops like paddy in traditionally wheat growing areas.

9. India has failed to take measures to recharge groundwater adequately in northern part.

10. Wheat cultivation in India requires comparatively more water than paddy.

11. Water level in other parts of India is stable during the last decade.

12. India has now put in place a system to reduce over dependence on groundwater.

13. Adequate monsoon helps in drawing less ground water for cultivation and thus preserve balance.

In making decisions about important questions, it is desirable to be able to distinguish between “strong” arguments and “weak” arguments. “Strong”

arguments must be both important and directly related to the question. “Weak”

arguments may not be directly related to the question and may be of minor importance or m ay be related to the trivial aspects of the question.

Directions (Q. 14-18) Each of the questions below consists of a question and two statements numb ered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and give answer:

a) If the data in Statement I alone are sufficient to answer the question, while the data in Statement II alone are not sufficient to answer the question.

b) If the data in Statement II alone are sufficient to answer the question, while the data in Statement I alone are not sufficient to answer the question.

c) If the data either in Statement I alone or in Statement II alone are sufficient to answer the question.

d) If the data even in both Statements I and II together are not sufficient to answer the question.

e) If the data in both Statements I and II together are necessary to answer the question.
