(A) that would investigate changes in working conditions as to their effects on workers' performance
(B) investigating the effects that changes in working conditions would have on workers' performance
(C) for investigating what the effects on workers' performance are that changes in working conditions would cause
(D) that investigated changes in working conditions' effects on workers' performance
(E) to investigate what the effects changes in working conditions would have on workers' performance
答案是B
请问E为啥不对 我看有的帖子说E没有what从句中没谓语,但是为什么不能想成what the effects是一起的,一起做have的宾语,就像是我们常说的what effect it would have 或者是what time it is now这种用法、
这样为什么不可以
