标题: CXD逻辑8,N哥请进!√ [打印本页] 作者: gedn01 时间: 2010-2-22 12:36 标题: CXD逻辑8,N哥请进!√ 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 interpretion 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 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 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 答案稍后给 但读来觉得 5个选项都不靠谱作者: honglu09 时间: 2010-2-23 16:31
我觉得是B吧。作者: first1121 时间: 2010-2-23 17:39
B 吧、、因为drab workroom 最多提供65个人的空间，所以100人中移走50后，只剩下50人 所以工作效率提高了。。所以这是不同于题目结论的另一种解释作者: fong1988 时间: 2010-2-24 03:21
I also think that B makes sense here.
But what is the correct answer? Please advise.

现在读来还不明白，选Ｂ有什么原因。 most doubt upon the author's interpretion of the study results given above 削弱的点我还是在原文中定位不出来
