还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
A. 这里写investigate changes。看到B应该就会有感觉，改变不需要调查，只需要观察就可以了。只有effect 才需要调查。
B. 正确。investigating 做后置定语修饰 experiment
C. 介词短语做名词的定语，和ing做定语不一样。介词短语的话没有主词，没有动做的发出者。for investigate，发出这个动作的对象就不是 实验了，错误。
D. experiment 只能在从句中做主语，做investigate的动作发出者，不行，错误 又是调差改变，错误同A
E. what 指代something that。
changes in working conditions would have on workers' performance 在effect后面做定语，因为effect 在从句中做宾语，所以that可以省略。
