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. 对于答案A不太明白是怎么削弱的,"那些参加plan的自觉独立的工人们"与"实施这个plan"有什么关系啊?到底削弱了哪一点啊? 请各位xdjm帮忙解答一下,mm在这里谢谢了~~~~~~~

因为The employees who agreed to participate in the test of the plan were among the company’s most self-motivated and independent workers. 这种人是最适合working from home的。所以这个sample base并不能代表整个员工群体。
