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
答案E
这句话为什么不是按照“A（猩猩很独特）或者B（如果我们同样深入研究其他动物，它们也会展示出同样的规律）还不确定”来理解？即： it is unclear whether... or...

It is unclear whether... or, whether... 对称的结构，楼上很对～作者: egwucj 时间: 2011-5-11 22:25
if可以理解为不是引导表语从句，而是or后面小分句的状语从句啊
