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.
A
为什么D不对呢？E中说明了这些自愿者的特点。能够在家里工作。这不正好说名了XYZ公司的测试不能代表公司的其他员工吗。就是说这些参加测试的员工可以在家里工作，但是其他的员工并不一定啊。
问题是“most strongly against deciding”
D中没说其他员工不能啊，而且句意表达很一般。A的话，有“were among the company’s most self-motivated and independent workers”，用most 有强烈对比的含意。
D虽然没有说其他人，但是说了这些自愿着，也就是说XYZ做的测试没有代表性。并不能代表整个公司的员工了。
不过如果说选最好的，那我就没什么可说的了。不过只想弄清楚。3X。
