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 above?
(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.
B is the best answer.
The data used to support the conclusion come from the companies’ own records. Since, however, choice B indicates that, as compared with Company O, Company P tends to overstate the number of job-related accidents, choice B weakens the conclusion drawn and is the best answer.
1Choice A does not weaken the conclusion, but is simply a consequence that would be expected given the data. 2The relevance of employees’sicknesses (choice C) cannot be assessed without information about the links, if any, between sickness and job-related accidents. 3Choices D and E both give reasons for predicting a smaller likelihood that any arbitrary employee of Company O will have a job-related accident, and thus support the conclusion.
不明白关于D、E的解释?牛牛指教!谢谢!
感觉d.e都是无关选项怎么是支持结论的呢,不明白
根据og解释理解是涉及出事故的工人越少和机器越少,就表明工人出事故的可能性越小,不知道这样理解对不对
我也有同样的问题,请NN指教。

D和E对原题的结论是有明显的支持作用。
D选项可以这样来解:
比如说,O公司总体员工的素质都相当好、从来不犯错误(就象我们这类~~),只有一个“捣蛋鬼”--他每天上班就会捣蛋、制造accident。这样,去年一年下来,O公司所有的accident都是那个“捣蛋鬼”干的。而P公司呢?总体员工的素质不怎么滴,就当他们全是农民吧--他们经常犯错误。所以,去年一年下来,P公司累计的accient就比O公司多了。
好了,到了今年,O和P两家公司正好都要派人出差,O公司正好把那个“捣蛋鬼”派出去,派到西伯利亚去考察;而P公司也派了一个农民去那里测量西北风~~现在,我们再来看看两家公司的局势:O公司剩下的员工就全是优秀的员工了--他们从来不犯错误;而P公司剩下的还是一帮农民--他们还是会经常犯错误。--》所以就支持了题中的结论。
同样的道理,也可以解释E选项,因为D和E在逻辑上来说,本质是一样的(大家要不要自己试着解释一下?~~)。

没错。如果真要详细计算的话,会涉及到“概率论”方面的问题。有兴趣的话可以找本初等数学的书看看~~
橙子兄弟真是幽默啊~~喜欢看你的回帖, 不知道你现在杀G成功没有,是不是还在CD上, 若在的话,请多帮我们这些菜菜解答点问题, 让我们在复习GMAT的枯燥乏味之余也乐呵乐呵

YOU ARE RIGHT

说的不错! 橙子老哥!
脑子实在是转不过来,为啥 company p tends to overstate the number of job-related accidents 啦?
NN们给个例子好吗?
