16.   In a study of the effect of color on productivity, 50 of 100 factory workers were moved from their drab workroom to a brightly colored workroom. Both these workers and the 50 who remained in the drab workroom increased their productivity, probably as a result of the interest taken by researchers in the work of both groups during the study.

Which of the following, if true, would cast most doubt upon the author’s interpretation of the study results given above?

(A) The 50 workers moved to the brightly colored room performed precisely the same manufacturing task as the workers who remained in the drab workroom.

(B) The drab workroom was designed to provide adequate space for at most 65 workers.

(C) The 50 workers who moved to the brightly colored workroom were matched as closely as possible in age and level of training to the 50 workers who remained in the drab work-room.

(D) Nearly all the workers in both groups had volunteered to move to the brightly colored workroom.（B）

(E) Many of the workers who moved to the brightly colored workroom reported that they liked the drab workroom as well as or better than they liked the brightly colored workroom.

不太理解，请赐教

偶的理解不一定对，欢迎大家指教：

题目说在一个颜色对工作效率影响的调查中，在昏暗工作室中从100名工人中转移50名到明亮的房间工作，2组的工作率都提高了，也许是因为由于工人们对实验的兴趣导致他们工作效率增加。问削弱，b是他因的削弱-提出另一个原因使他们工作效率提高，原来的房间太小，只能容纳65人，现在大家工作空间增大，导致了效率的提高。

最近太忙，刚看见

谢谢，和最初得理解差不多

谢谢
