Dear Sir/Madam,
According to Manhattan SC book, which says the following:
Use WHICH only to refer to the noun immediately preceding it-never to refer to an entire clause.
Based on that i eliminated the answer choice (D) and (E) in
[deleted because problem is from a banned source - see below]
Correct answer is (E) but in this choice which is referring to Dickinson not to letters.
Any explanation on this?
looking forward for your replay.
Thanks,
regard,
ravi.
