80.    (29100-!-item-!-188;#058&003474)

Given that employees of the XYZ Company could, in theory, do their work at home, the company developed a radical plan to increase efficiency:  eliminate office-space expenditures by having employees work at home.  To evaluate this plan, XYZ’s managers asked volunteers from the company’s staff to try the arrangement for six months.  There were several volunteers; significantly, their productivity during this period 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 implementation of the plan apart from any productivity increases.
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. Recent changes in the way work is organized at XYZ’s company offices have not brought about any productivity increases.
我选对了A，但是E不知道为什么不对。求大侠指点啊！

Recent changes in the way work is organized at XYZ’s company offices have not brought about any productivity increases.
没有A削弱的充分吧。
即使E为真，也不能说明公司的计划不能降低支出。可能是大家还不适应啊之类的。

A直接对支持结论的试验进行削弱，更好。
