UPSC Prelims 2014 CSAT Paper 2 Answer Key

This is the answer key for Set B.

Friends, each year, after the exam, there is a substantial confusion regarding answer keys – various answer keys don’t match and students are left in confusion. So this year, me and Prem Ranjan ji (IAS rank 62, cse 2013) (https://www.facebook.com/Prem.Ranjan.Singh.1985 ) have tried to come up with the following key after doing as much internet research as we could. Still there might be some grey areas and we are open for discussing these.

 

My personal opinion on the paper, passages I found it substantially tougher than last year.
