Directions : Each of the following question consists of a statement followed by two arguments I and II. You have to decide which of the arguments is a STRONG arguments and which is a WEAK Argument. Statement : Should there be a maximum limit for the number of ministers in the Central Government Arguments : I. No. The political party in power should have the freedom to decide the number of ministers to be appointed. II. Yes. The number of ministers should be restricted to a certain percentage of the total number of seats in the parliament to avoid unnecessary expenditure.?
Answer: Option 2 Clearly, there should be some norms regarding the number of ministers in the Government, as more number of ministers would unnecessarily add to the Government expenditure. So,...

Directions : Each of the following question consists of a statement followed by two arguments I and II. You have to decide which of the arguments is a STRONG arguments and which is a WEAK Argument. Statement : Should higher education be restricted to only those who can bear the expenditure Arguments : I. Yes. Higher education is very costly; hence it should not be given free. II. No. There are a large number of brilliant students who cannot afford to pay and they should be given higher education.?
Answer: Option 2 For the all-round progress of the nation, all the students, especially the talented and intelligent ones, must avail of higher education, even if the government has to...

Statement : A large number of engineering graduates in the country are not in a position to have gainful employment at present and the number of such engineers is likely to grow in the future. Courses of Action : I. The government should launch attractive employment generation schemes and encourage these graduates to opt for such schemes to use their expertise and knowledge effectively. II. This happened due to proliferation of engineering colleges in the country and thereby lowered the quality of the engineering graduates. Those colleges which are not equipped to impart quality education should be closed down.?
Answer: Option 2 The emphasis should be not on the Government putting all the engineering graduates to jobs but on the colleges producing not 'degree-holders' but real technical minds which...
