KAPLAN OFFICIAL EXPLANATION:
A.
“Not only . . .but also” must connect similar terms. “Deep sea divers not only risk” and “but also fall prey” are correctly paralleled in (A). (B) would work if“and”was substituted for “but.”There are two prob- lems with (C): “nitrogennarcosis . . . is risked” and the fact that (C) is actually two complete sentences incorrectly linked with a comma.You’d need a period after “feet,” anda capital “i” in “in.” In(E), “they” doesn’t refer clearly and unambiguously to one spe- cific plural noun. In (A),“they” can mean only “divers.”(D) The beginning of this sentence is a bit wordy and “causes themrisking . . .” sounds awkward. The infinite “to risk” is needed in place of “risking.”
