(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:B, 这道题答案中的on究竟是跟effects对应还是changes, 做了两次都选错了. 请大家指教!

Yes, my answer is E. But in B, I think the that clause is the attributive clause of effects, and the "on" is related to "effects". Don't you think so?

Read the question again, I make clear that why investigating is better than to investigate. Because the whole sentence is "... works... was ...... of experiments", after that we should choose a choice to modify the experiments, not to describe the purpose of the whole sentence. So here "investigating" is better than "to investigate". Right?
