OG16 第88题，求解释！T-T

Debater: The average amount of overtime per month worked by an employee in the manufacturing division of the Haglut Corporation is 14 hours. Most employees of the Haglut Corporation work in the manufacturing division. Furthermore, the average amount of overtime per month worked by any employee in the company generally does not fluctuate much from month to month. Therefore, each month, most employees of the Haglut Corporation almost certainly work at least some overtime.

The debater's argument is most vulnerable to criticism on which of these grounds?

(A) It takes for granted that the manufacturing division is a typical division of the corporation with regard to the average amount of overtime its employees work each month.

(B) It takes for granted that if a certain average of amount of overtime is worked each month by each employee of the Haglut Corporation, then approximately the same amount of overtime must be worked each month by each employee of the manufacturing division.

(C) It confuses a claim from which the argument's conclusion about the Haglut Corporation would necessarily follow with a claim that would follow from the argument's conclusion only with a high degree of probability.

(D) It overlooks the possibility that even if, on average, a certain amount of overtime is worked by the members of some group, many members of that group may work no overtime at all.

(E) It overlooks the possibility that even if most employees of the corporation work some overtime each month, anyone corporate employee may, in some months, work no overtime.




我一开始比较纠结的是D和E，后来看了网上的翻译和解释后，觉得是题目出的有问题了
对于题目给定的调查事实：H公司所有员工的平均OT每个月都变化不大，比较稳定。不是应该说明了该公司真得所有员工都每个月加了班吗？不然应该说加班员工的平均OT差不多才对啊。这个又不是Debater 推理来的。
然后如果他推理的结果是 该公司每个月大多数人都加班，E不就通过以有些人在某些月份不加班来反驳了它吗？在这里反驳的点在于是不是每个月加班啊，不对吗？


纠结到头痛，求指导

我给你一种情况，你看看符不符合题干中的要求：
一个部门有很多员工，但是有少数人总加班，一个月加100小时，多数人总也不加班。结果这些人的平均加班是14小时每个月。

这个我懂，我是回过头来看那句说 H公司所有员工平均加班时间每个月都差不多 之后觉得说有人加很多班，有人一点班都不加很矛盾
那么为什么不可以以反驳他们不是所有人都每个月加班呢？

你找错结论了。。。。
结论：most employees of the Haglut Corporation almost certainly work at least some overtime.
削弱：
most employees of the Haglut Corporation almost certainly NOT work at least some overtime.

E选项： It overlooks the possibility that even if most employees of the corporation work some overtime each month, anyone corporate employee may, in some months, work no overtime.
注意even if most employees of the corporation work some overtime each month这不就是结论吗？E等于肯定了结论，没有削弱。

所以原文结论前面的 each month 并没有关系是吗？它不是真正要强调的内容？

一般情况下GMAT CR都只会要求你削弱结论或者逻辑关系，而不会要求你削弱论据。也就是论据中的内容，我们都是当做“事实”来对待的。
相比较于直接削弱结论和因果关系，削弱论据对argument的削弱程度就要弱很多。因为即使我可以证明在某些情况下论据不成立，也无法削弱在论结成立的情况下，argument成立的事实。
举例：
在你不明白的情况下，这题你做不出来。
削弱：
1. 在你不明白的情况下，这题你做出来了。

可如果你能够证明你明白，能证明什么的？跟在你不明白的情况下这题你能不能做出来有什么关系？
