Question 1
4 / -1

You are presented with a paragraph with options (1), (2), (3), (4) and (5). Read the paragraph carefully and identify which of the given options correctly explains the paragraph or correctly summarizes it, if none of the options correctly explains it mark (5) as your answer.
Fossils found deep in South Africa's Rising Star cave complex in 2013 have been dated by several expert teams with their findings suggesting the hominids, called Homo naledi, may have lived alongside Homo sapiens. It had earlier been thought that the hominids were millions of years old. A team of 20 scientists from laboratories and institutions around the world, including in South Africa and Australia, established the age of the fossils which suggests that Homo naledi may well have lived at the same time as humans. The focus of the team's research has been South Africa's barely accessible Rising Star Cave system, part of the Cradle of Humankind World Heritage Site, about 50 kilometers northwest of Johannesburg. The area has been an incredibly rich source of artifacts.

A
After analyzing fossils of the Homo sapiens, found deep in a cave system in South Africa, a team of researchers have concluded that Homo naledi, distinct relatives of Homo sapiens, probably existed at the same time as Homo sapiens.

B
Rising Star Cave system, an area which has been a rich source of artifacts, in South Africa has revealed that Homo naledi may have lived alongside Homo sapiens after a thorough examination of fossils found there.

C
Homo sapiens have lived at the same time as Homo naledi, once presumed now has been confirmed by the fossils found in South Africa's Rising Star Cave system, established by a team of researchers.

D
Hominids, though to be millions of years old, probably existed at the same time as Homo sapiens revealed by a team of researchers after analyzing fossils found in South Africa's Rising Star cave system.

Solution

Option 1 cannot be the summary as it entails that fossils found belonged to Homo sapiens which is incorrect, option 2 also renders wrong information - Rising Star Cave system is not being mentioned as an area which has been a rich source of artifacts, Option 3 suggests that it was already presumed that Homo sapiens lived with Homo naledi which is incorrect as per the paragraph. Option 4 is the correct choice.
Question 2
4 / -1

You are presented with a paragraph with options (1), (2), (3), (4) and (5). Read the paragraph carefully and identify which of the given options correctly explains the paragraph or correctly summarizes it, if none of the options correctly explains it mark (5) as your answer.
Under normal market conditions, for customers debt funds have nearly the same liquidity as term deposits with banks. However, given illiquid bond markets, they can have serious liquidity problems. The banking system has access to a liquidity window run by the regulator that allows it to tide over any short-term liquidity challenge, including, at its extreme, a bank run. Currently, no such strong liquidity support exists for credit funds. There is the collateralized lending and borrowing operation (CBLO) run by Clearing Corporation of India but with rapidly growing credit funds, this window is grossly inadequate. So we should consider providing liquidity adjustment facility (LAF) access to credit funds too. This would ensure that in the event of a "fund run" there is enough access to liquidity for funds.

A
Although CBLO is available, it is not adequate in solving all liquidity problems for credit funds, so a need arises for a new liquidity window for credit funds.

B
When the need arises, Banks can approach LAF window for all liquidity problems, credit funds have nowhere to go so they should be given access to LAF window too.

C
In case of a liquidity problem, credits funds should also be given access to LAF window same as banks as CBLO is often inadequate for both of them.

D
None of the above

Solution

suggests a new liquidity window which is incorrect as per the paragraph (which suggests LAF only), option 2 mentions that credit funds have nowhere to go when liquidity problem arises which is incorrect (they have CBLO but it is inadequate), option 3 suggests that CBLO is inadequate for banks also which is incorrect, option 4is the correct choice.
Question 3
4 / -1

You are presented with a paragraph with options (1), (2), (3), (4) and (5). Read the paragraph carefully and identify which of the given options correctly explains the paragraph or correctly summarizes it, if none of the options correctly explains it mark (5) as your answer.

Rational choice theory assumes that all people try to actively maximize their advantage in any situation and therefore consistently try to minimize their losses. The theory is based on the idea that all humans base their decisions on rational calculations, act with rationality when choosing, and aim to increase either pleasure or profit. Rational choice theory also stipulates that all complex social phenomena are driven by individual human actions. Therefore, if an economist wants to explain social change or the actions of social institutions, he needs to look at the rational decisions of the individuals that make up the whole.

A
As per Rational choice theory, all the decisions taken by people are in their highest self-interest so any social change or planning driven by these individual decisions lead to a quintessential outcome.

B
Rational Choice theory suggests that all complex social phenomena can be explained in terms of the elementary individual actions, only the ones which are rationally motivated, of which they are composed.

C
As per the Rational Choice theory, rational individuals choose the alternative that is likely to give them the greatest satisfaction together building any social phenomena that is motivated by profit.

D
Rational choice theory postulates that individuals always make prudent and logical decisions, which provide people with the greatest benefit or satisfaction, and all social phenomena are reducible to these individual decisions.

Solution

Option 1 does not mention that individuals take rational decisions, option 2 incorrectly states that only those individual actions which are rationally motivated make up a social phenomenon but the paragraph says all individuals make rational choices only so there are no irrational choices as per the theory, option 3 also incorrectly states that rational choices only make up those social phenomena which are motivated by profit, option 4 is the correct choice (prudent and logical decisions are rational decisions).

Question 10
4 / -1

Read the following passages/statements and answer the questions that follow them.

Statement: Working from the comforts of their own homes should, in theory, improve employee well-being. However, new research suggests that working from home may have more disadvantages than perks.

Which of the following can be inferred from the given statement?

1. There are other research which suggest that working from home have more perks than advantages.

2. There is an option of working from home provided by companies/organisations.

3. Working from the comforts of their own homes doesn't improve employee's well-being in practicality.

A
2 and 3 only

B
1 and 2 only

C
1 and 3 only

D
2 only

Solution

1- no inference can be made about other research since the statement doesn't talk about it; 2- it can be inferred from the first sentence in the statement. 3- it's partially true based on the suggestion of the new (single) research; therefore, cannot be inferred in totality. Hence, (d) is the right answer.
