OG-191 是在反对assumption吗?

海蓝

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.

选A.

请教一下,这道题是反对assumption还是premise? 反对assmption和premise题的区别是什么啊?~~我总是分不太清~~

我想试着按自己的思路分析一下,大家帮着看看对不对.

题目类型是A-B结构的断桥型削弱. A(前提)是个试验,结果为productivity不变/提高,B(结论)是措施可行. A选项说那些工人都是自觉独立的工人是在反对实验结果和措施可行的相关性, 是在weaken assumption.

这个思路正确吗?~~

这道题的思路考的是局部与整体的关系，局部正确不代表整体正确（反之亦然），典型原因是局部具有非整体所具有的属性（整体的分布与局部的分布不同）

类似的考点有相对数和绝对数的关系。

谢谢小安,再问一下,这道题是你说的那种weaken assumption题吗?

anchoret

不是。我说的那种weaken assumption是直接反对原文。不过没关系，那类题很少，不用担心

OG的解释E好像有问题哟。看得我直郁闷，前半截。

Choice E is incorrect; since reduced office-space expenditures, rather than productivity increases, would be the goal of implementing the plan, the fact that alternative measures might achieve equal productivity gains is not directly relevant

OG的解释不会有问题的。

OG的解释没有问题，“实施这项改革的目标是减少办公公共开支，而不是提高生产力，那么E提供的另一种同样可以提高生产力的方案与本题的宗旨不直接相关”

细想一下，ETS的解释是没错，但是就是太concise了。

应该是E和这个trial和plan都无关。

这题好象代表一种类型：为达到目的A，实施方案B，实现目标A的同时得到结果C。结论：方案B可行。

削弱结论的思路就是小安在2楼说的。

不知我说的对不对，也希望大家找出同类型的题目。

其实这道题，ETS已经在题干里好心地提醒了我们要：

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?

因此一切评估都要以TRIAL的结果来分析。
