[求助]prep1—70 谢谢各位了

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

E正确

不是针对答案的疑惑有两点

1. whether因的应该是主从 但or前为什么有逗号啊

2.they和their明显指代不一   是不是本题要暂且忽略这个问题 指代不一仍可作为标准

谢谢各位啦
