UPSC 2017 CDS II English Paper

‘R’ will be the first part of the given sequence as it combines with the phrase ‘last summer’ in order to form the subject clearly. Q will come next in order to maintain the rule of subject-verb agreement. SP will make a pair together as ‘with phone calls’ is used in relation to ‘pestering’ and P will be the last part as ‘with phone calls every day’ makes a logical phrase together. Hence, RQSP is the right sequence. Thus, option (c) is correct.
