求助OG10-191 谢谢!!

191。 To evaluate a plan to save money on office-space expenditures by having its employees work at home, XYZ Company asked volunteers from its staff to try the arrangement for six months. During this period, the productivity of these employees was as high as or higher than before. Which of the following, if true, would argue most strongly against deciding, on the basis of the trial results, to implement the company’s plan?

(A) The employees who agreed to participate in the test of the plan were among the company’s most self-motivated and independent workers.

(B) The savings that would accrue from reduced office-space expenditures alone would be sufficient to justify the arrangement for the company, apart from any productivity increase.

(C) Other companies that have achieved successful results from work-at-home plans have work forces that are substantially larger than that of XYZ.

(D) The volunteers who worked at home were able to communicate with other employees as necessary for performing the work.

(E) Minor changes in the way office work is organized at XYZ would yield increases in employee productivity similar to those achieved in the trial.

对于A选项还是不太明白怎么削弱的? 那些同意参加plan的工人都是自觉独立的工人,与可以实施plan有什么关系啊?

不太明白,希望各位xdjm帮忙!!!!

这是一类题,公司想推广这个计划(从个性到共性)，但有一个明显的断桥削弱，就是这些个性不能代表共性就可以有（即参加测试的人本身自觉性就很强,不能代表所有的员工,言外之意,如果一些混混儿参加测试,效果可能就不是这样了）

本题最大的问题就是样本不具代表性.

偶觉得此类题可以先从题干理出一个思路reasoning,再找答案相对容易些.

哦,....

哈哈~~~~~终于明白了,谢谢~~~~~~~~~~~~~

zhaoyak7你说的很明白,谢谢!~~~~~~~~~~~~~~~~~~~~
