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
原文意思：大猩猩是否在畜生中是独特的并且其他动物是否也具备大猩猩的能力都不太清楚
题目分析：两个事情进行了并列，前面用whether后面形成并列的就只有D和E了，前面whether后面跟的是动物，那后面whether后面应该也马上说动物才能和前面的 whether chimpanzees 保持对应，选E。
