11. In which state the Feast of St. Francis Xavier festival is celebrated?

Correct Answer: B. Goa
Solution:The feast of St. Francis Xavier is one of the most important festivals in Goa. Though essentially a Christian festival, all Goans irrespective of their caste and religious faiths come to the Basilica of Bom Jesus located in Old Goa to participate in the feast. St. Francis Xavier was a revered saint who came to Goa along with the Portuguese to spread Christianity. His mortal remains are still preserved in the Basilica of Bom Jesus in Goa.

The British government led by David Cameron held a referendum on the issue on 23 June 2016; 51.89% voted to leave the EU and negotiations on the terms started on 19 June 2017 with the UK remaining a full member of the European Union until the UK leaves the EU at the expected and agreed date.

13. Who discovered the neutron in 1932 while working at Cavendish Laboratory?

Correct Answer: A. James Chadwick
Solution:The story of the discovery of neutron and its properties is central to the extraordinary developments in atomic physics that occurred in the first half of the 20th century.

The century began with Ernest Rutherford and Thomas Royds proving, in 1908, that alpha radiation consists of helium ions, and Rutherford's model for the atom in 1911, in which atoms have their mass and positive charge concentrated in a very small nucleus. The essential nature of the atomic nucleus was established with the discovery of the neutron by James Chadwick in 1932.

14. The point at which the budget line just touches, one of the ________ curves would be the consumer's optimum.

Correct Answer: D. indifference
Solution:An indifference curve is a line showing all the combinations of two goods which give a consumer equal utility. In other words, the consumer would be indifferent to these different combinations.

We can also show different indifference curves.

All choices on 12 give the same utility. But, it will be a higher net utility than indifference curve 11.

14 gives the highest net utility. Basically 14 would require higher income than II.

15. Which of the following is true with respect to SMC (Short run marginal cost) and SAC (Short run average cost)?

Correct Answer: D. SMC curve cuts the SAC curve from below at the minimum point of SAC
Solution:SMC (i.e., MC) curve custs SAC (i.e., AC) curve from below at minimum point of AC curve show in the figure As long as SAC is falling, SMC is less than SAC and when SAC is rising, SMC is greater than SAC. So SMC curve cuts SAC curve from below at its minimum point.

16. A glass factory hires 11 craftsmen by paying each of them ₹ 1100 per day. The 12th craftsman demands ₹ 1200 per day. If this craftsman is hired then all other craftsmen must be paid ₹ 1200. The marginal resource (labour) cost of the 12th craftsman is __________.

Correct Answer: B. ₹ 2,300
Solution:No explanation given in the book

17. ___________ is the ratio which requires the banks to maintain a given fraction of their total demand and time deposits in the form of specified liquid assets.

Correct Answer: C. Statutory liquidity
Solution:RBI uses various instruments for healthy Reserve Deposit Ratio in commercial banks:

(a) Cash Reserve Ratio which specifies the fraction of their deposits that banks must keep with RBI.

(b) Statutory Liquidity Ratio which requires the Banks to maintain a given fraction of their total demand and time deposits in the form of specified liquid assets.

18. Net National Product at market prices - Net indirect taxes =

Correct Answer: A. Net National Product at factor cost
Solution:Let us presume that the actual cost of producing a certain output is₹ 100, which is given to different factors of production as wages, rents, interest and profits. The Government imposes taxes worth ₹ 25 on this output so that it is sold in the market for ₹ 125.

This is the market value of output, while income payments made to factors of production amount to ₹ 100 only. Thus, from the money value of NNP at market price or NNI we deduct the amount of indirect taxes to arrive at the net national income at factor cost.

NNP at MP - Indirect Taxes = Net National Income at Factor Cost

19. Due to large quantities of nutrients in water an excessive growth of planktonic __________ occurs.

Correct Answer: C. algae
Solution:Pollution is potentially among the most damaging of all human influences on the oceans, in terms of both scale and consequences. Excessive nutrient inputs can turn marine areas into "dead zones" almost devoid of higher animal life. Nutrients discharged in large quantities into coastal waters promote blooms of planktonic and benthic algae. Phytoplankton blooms contribute to increased water turbidity, reducing light penetration and adversely affecting pelagic and benthic biological communities.

20. Relative contribution of which of the following green house gases is the most towards total global warming?

Correct Answer: C. Carbon dioxide
Solution:Estimates of relative contributions to additional greenhouse forcing during particular periods do not fully take into account differences in atmospheric residence times among the important greenhouse gases. Here we extend recent work on halocarbons 5. 6 by proposing an index of global warming potential for methane, carbon monoxide, nitrous oxide and CFCs relative to that of carbon dioxide.

We find, for example, that methane has, per mole, a global warming potential 3.7 times that of carbon dioxide. On this basis, carbon dioxide emissions account for 80% of the contribution to global warming of current greenhouse gas emissions, as compared with 57% of the increase in radiative forcing for the 1980s.
