I eliminated choice (c), (d),and (e) on the basis of 4th paragraph. I narrowed down to both (a) and (b). Although I do understand choice (b) is not mentioned on the passage, I do not clearly understand whether (a) is mentioned on the passage either implicitly or explicitly.
Please, explain why (a) can't be the answer.
