求鉴定这个分类对么？

sephone1992

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 increases.

(C) Other companies that have achieved successful results from work-at home plans have workforces 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.

这个看起来是方案模式，但因为有对这个方案进行评估（the productivity of these employees was as high as or higher than before），所以应该是因果推理

因是：XYZ Company asked volunteers from its staff to try the arrangement for six months

果是：the productivity of these employees was as high as or higher than before

所以思路应该是把选项加在因和果之间，即看选项＋因是否可以＝果

A选项削弱了这个因果，因为它把这个因给局限了，所以是答案；

B选项说省出来的除了可以增加工作效率，同时也有效的证明了公司的安排，这个应该是i加强吧

C选项说另一个通过在家工作的方法获得成功的公司有更多的职员，这个无关吧；

D选项加强了因果关系，它说在家可以和别的职员沟通，也就是说在家＋和职员沟通＝高效，所以是加强

E选项有点不知道怎么说……

求大神指正一下～
