Companies O and P each have the same number of employees who work the same number of hours per week.  According to records maintained by each company, the employees of Company O had fewer job-related accidents last year than did the employees of Company P.  Therefore, employees of Company O are less likely to have job-related accidents than are employees of Company P.



Which of the following, if true, would most weaken the conclusion?



(A) The employees of Company P lost more time at work due to job-related accidents than did the employees of Company O.

(B) Company P considered more types of accidents to be job-related than did Company O.

(C) The employees of Company P were sick more often than were the employees of Company O.

(D) Several employees of Company O each had more than one job-related accident.

(E) The majority of job-related accidents at Company O involved a single machine.

我选的D，也就是O公司出事故员工的事故数比较多，那么虽然总事故多，但是人数还是比较少的，所以削弱了原文结论。为什么不对呢？
请大牛解释啊~~~谢谢啦！！！

up!

楼主看清选项
(D) Several employees of Company O each had more than one job-related accident.

说的是只有一些有多余1个的事故，却没有说等于1的，如果很多人都有等于1个呢？那么事故不就很多了么

不好意思啊，我好像弄错了，D是加强原文结论的。

这个是网上下的解释


(A) The employees of Company P lost more time at work due to job-related accidents than did the employees of Company O.
比较的范错误的多少和可能性的问题，和犯错误浪费了多少时间无关
(B) Company P considered more types of accidents to be job-related than did Company O.
正确，P公司接触的错误的种类更多所以每一种错误的犯错率不一定高
(C) The employees of Company P were sick more often than were the employees of Company O.
员工的体质状况属于无关
(D) Several employees of Company O each had more than one job-related accident.
只是说了几名员工不具有代表性
(E) The majority of job-related accidents at Company O involved a single machine.
机器不能对结论产生削弱作用

这题应该选B吧。

A：P公司的员工出事故后休息的时间更长，那么平均来说P公司的在工作的员工比O公司的少，但是出事故的却更多，这个是加强结论。

B：P公司把更多的事故考虑为工伤，所以P公司的工伤数目更多，这个就是削弱

C：生病，没提到与工伤的关系，无关。

D: 极端来说，O公司的工伤都是这几个人造成的，赶走了就没工伤了，加强。而且several听着就不像正确选项，我记得有人说过，逻辑题中出现some的一般都不是正确选项。

E：如果不是无关，那也是加强

我是从概率的角度看的,因为问题中提到了less likely to.所以应该是job related accidents/all accidents
(A) The employees of Company P lost more time at work due to job-related accidents than did the employees of Company O.
说因为job-related accidents,Company P的人损失更多工作时间,是说它造成的结果,对原文无作用
(B) Company P considered more types of accidents to be job-related than did Company O.
可以直接作用削弱原文,说P公司相比O公司把更多accidents算成job-related.所以公式的分子变大了,P公司的概率就大了.
(C) The employees of Company P were sick more often than were the employees of Company O.
P员工生病比O多,和accidents没什么关系
(D) Several employees of Company O each had more than one job-related accident.
几个O公司的人出工作意外的次数不止一次.这个方向确实反了,因为O公司有猛将"以1顶2,顶3",结果数量还不及P公司的accidents多,只能让我更加相信O比P less likely.因为即使假设O公司的其他人没有发生一次job-related意外(不可能发生负意外抵消),P公司要比O多,一定要有个人或集体上比这several employees发生更多job-related意外才行.
(E) The majority of job-related accidents at Company O involved a single machine.
机器有什么用不知道.
