A looks fine to me


A. are unaware of the contributions of Srinivasa Ramanujan, a genius who in his short career produced a number of theories that are breathtaking

his correctly points to ramanujan

are(plural) for theories

i dont think "had produced " is needed here ..is it? :?

It's definitely A.

The bolded portions indicate where B, C, D, and E are wrong:

B. are unaware of the contributions of Srinivasa Ramanujan, a genius who in his short career produced a number of theories that had been breathtaking

C. are unaware of the contributions of Srinivasa Ramanujan, a genius who in his short career had produced a number of theories that are breathtaking

A should be it.

1. correct sequence of tense: .....are........ and ..........produced.
2. correct SV agreement: ......a number of theories that are..................

Had been implies that this occured in the past somehow before another event.... however the results still ARE breathtaking, so 'had been' is wrong.

Quote:
C. are unaware of the contributions of Srinivasa Ramanujan, a genius who in his short career had produced a number of theories that are breathtaking


Had produced implies that he produced these proofs BEFORE his career... past perfect tense is wrong here.

Quote:
D. are unaware of the contributions of Srinivasa Ramanujan, a genius who in his short career produced a number of theories that is breathtaking


Obviously wrong

Quote:
E. had been unaware of the contributions of Srinivasa Ramanujan, a genius who in his short career had produced a number of theories that is breathtaking


again had produced is wrong.

Please explain your answer.


A it is. A clearly states that students are unaware (currently). The mathematician produced a number of theories that are breathtaking is clear.

B. "that had been breathtaking" suggests that they are no longer breathtaking.

C. here had is not needed b/c simple past works just fine. Also we have no other previous happening in the past besides te creation of theories, thus no need for had.

D. "that is" does not agree w/ a number of. requires plural "are"

E. Students had been unaware? and "had produced" doesn't make sense.
