请问OG10-CR-114的C选项

题目是这样的

The more frequently employees take time to exercise during working hours each week, the fewer sick days they take. Even employees who exercise only once a week during working hours take less sick time than those who do not exercise. Therefore, if companies started fitness programs, the absentee rate in those companies would decrease significantly.

Which one of the following, if true, most seriously weakens the argument above?

A)    Employees who exercise during working hours occasionally fall asleep for short periods of time after they exercise.

B)     Employees who are frequently absent are the least likely to cooperate with or to join a corporate fitness program.

C)    Employees who exercise only once a week in their company’s fitness program usually also exercise after work.

D)    Employees who exercise in their company’s fitness program use their working time no more productively than those who do not exercise.

E)     Employees who exercise during working hours take slightly longer lunch breaks than employees who do not exercise.

OG答案是B。偶对答案没有问题，但认为C也可以做答案。

我对C的推理是：原文说：那些每周在办公时间锻炼一次的员工请病假缺席的可能性低。选项C说：那些每周在办公时间锻炼一次的员工，也通常在下班后锻炼身体，这里就给说了一个他因，就是“下班后锻炼”。所以，如果公司的结论是，推出办公时间的健身计划，员工的请假缺席率会降低。因为这个计划忽略了选项C提出的他因“下班后锻炼很重要”，所以选项C起到了对结论的weaken作用。

不知道偶的推理错在哪里，请大家帮忙看看，想了好久了还是想不通，谢谢

刚做了这道题,觉得C选项看似合理,但不是the best answer, 原文中最后一句话:......the absentee rate in those companies ....和C选项中:.....usually also exercise after work....没有任何联系. 这道题目的突破点应该是在frequently...absentee rate. 所以B选项是最贴切的.

感谢fabulous80。这个frequently的关键词确实点播了我的想法。总结了一下，觉得应该这样推理C选项不正确的原因。原文中，一开始说了这个事实，“越常锻炼，越少请病假”，然后相当于举个例子地说，即使每周锻炼一次的人也比不锻炼的人在缺勤率方面强。试想，在所有锻炼的人中，“每周只锻炼一次”的人和“每周frequently锻炼的人”比较，占百分之几呢？从原文中无法推出，所以C无法起到充分weaken作用，或者说weaken的作用性无法确定。假如原文说，每周只锻炼一次的人占所有有锻炼的人的总数的90%，或者甚至100%,那么这些只锻炼一次的人的其他锻炼习惯,即“下班后继续锻炼”对缺勤率下降的他因作用就很大，C应该就可以选为答案了；但假如每周锻炼一次的人只占有锻炼的人的总数的5%，甚至不到，那么这些人下班后锻炼的他因作用就微不足道，C就不能算best answer。所以相比之下，B为最佳。

其实还有一点想法想补充。前几天不知道从哪里看来的一个NN总结，说是逻辑只要问到mostly weaken的选项，肯定只有一个选项是weaken的，其他选项要么是支持，要么是无关，绝对不会有什么一点点weaken的选项来干扰。这题就是一个很好的反驳该结论的例子。这题就是要选择best answer,即最most weaken的选项。OG10-178也是一个好例子，其C选项也是具有一定的weaken性，但不如答案weaken来得直接，来得爽快。

不知大家同意我的总结么？怯生生地问。

我开始也选的C，后来发现B是ETS思路似的的答案

就是要weaken就把因果倒置

类似的例子还有OG-48的E选项，以及以下这道lsat的E选项

Questions 22-23

Doctors in Britain have long suspected that patients who wear tinted eyeglasses are abnormally prone to depression and hypochondria. Psychological tests given there to hospital patients admitted for physical complaints like heart pain and digestive distress confirmed such a relationship. Perhaps people whose relationship to the world is psychologically painful choose such glasses to reduce visual stimulation, which is perceived as irritating. At any rate, it can be concluded that when such glasses are worn, it is because the wearer has a tendency to be depressed or hypochondriacal.

LSAT-8-4-22.       The argument assumes which one of the following?

(A) Depression is not caused in some cases by an organic condition of the body.

(B) Wearers do not think of the tinted glasses as a means of distancing themselves from ocher people.

(C) Depression can have many causes, including actual conditions about which it is reasonable for anyone to be depressed.

(D) For hypochondriacs wearing tinted glasses, the glasses serve as a visual signal to others that the wearer’s health is delicate.（E）

(E) The tinting does not dim light to the eye enough to depress the wearer’s mood substantially.
