15. (25243-!-item-!-188;#058&002297)
In the mid-1920s the Hawthorne Works of the Western Electric Company was the scene of an intensive series of experiments that would investigate changes in working conditions as to their effects on workers' performance.
(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

这道题我再选项B、D之间徘徊。。最后因为简洁有效我选了D，但是我看不出D有什么问题啊，笔记中解释的歧义我没有发现，还望高人指点！

最后，说说我错选的D，notes的解释是：表达不清晰，可以理解为changes in… effects，也可以理解为changes in working conditions
我觉得这个说法不对。这里并没有表意不清的问题，因为conditions'是所有格形式。根据OG解释，所有格形式的词的效用是形容词而非名词，如果其后有指示代词都无法指代，何况是逻辑上的歧义。
D的问题很明显是偷换概念，改变了原有逻辑重心，investigate的宾语中心词毫无疑问是effects，而非changes。这里将effects放到了修饰changes的地位明显是不对的。
另外附OG R86题及其解释，这里仅摘取了对所有格的说明。
86．  Since 1986，when the Department of Labor began to allow investment officers’ fees to be based on how the funds they manage perform, several corporations began paying their investment advisers a small basic fee，with a contract promising higher fees if the managers perform well．
(A)  investment officers’ fees to be based on how the funds they manage perform，several corporations began
(B)  investment officers’ fees to be based on the performance of the funds they manage，several corporations began
(C)  that fees of investment officers be based on how the funds they manage perform，several corporations have begun
(D)  fees of investment officers to be based on the performance of the funds they manage，several corporations have begun
(E)  that investment officers’ fees be based on the performance of the funds they manage，several corporations began

The pronoun they lacks a referent．While they would seem to refer to investment officers’ , grammatically it cannot because investment officers’ is a possessive modifying fees, rather than a plural noun standing by itself. The sentence needs to be revised so that investment officers is a plural noun.
