It is unclear whether chimpanzees are unique among nonhuman species in their ability to learn behaviors from one another, or if, when other animals are studied in as much depth, similar patterns would be found.

(A) if, when other animals are studied in as much depth, similar patterns would be found

(B) if other animals were studied with as much depth they would exhibit similar patterns

(C) would similar patterns be found in other animals if they were studied in as much depth

(D) whether similar patterns would be exhibited in other animals that were studied with as much depth

(E) whether other animals would exhibit similar patterns if they were studied in as much depth

可是想请问E中的they是指代other animals和题目中的their指代chimpanzees，不是会发生指代不一致的问题吗??

结果我就因此选了D
