Q79.

To evaluate a plan to save money on office space expenditures by having it  employees work at home, xyzcompany aasked 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 folowing 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 agree to participate in the test of the plan were among the company's most self-motivated and independent workers.

(E) Minor changes in the way office work is organized at xyz company would yield increases in emplyoee productivity similar to thouse achieved in the trial.

还是不懂。提干是说这个结果是好的，所以公司向采用。E是说公司在做实验的同时还有一些其他的实验也会提高效率，这样使得不知道是那个试验造成好的结果。即还有别的原因，所以E我觉得也对。

以下是引用hlxyhrz在2007-11-1 16:15:00的发言：
关于削弱，most strongly against。是要你找出最为针锋相对的答案。e的选项，看似回答，实则回避，没有正面回答问题。或者说，与题干无关。这么说，楼主明白？

懂了！多谢！相信您也一定精通逻辑，也帮忙看看这个问题。
