标题: og11-38 [打印本页]

作者: lingshihong 时间: 2010-1-15 21:51 标题: og11-38

有过工作相关事故的员工，o公司比p公司少。（比较的是人数，而不是事故数。）

那么如果o公司里某些员工一个人就发生好几次的话，实际事故数可能大于p公司。

因此，d答案也是weaken了结论的啊。

请帮我看看，我的理解哪里出问题了？

Questions 37-38 are based on the following:
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.

38. 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.

D 不一定会达到你所说的结果

如果F的选项由于O的员工发生了不只一次事故,导致总的事故数量超过了P. 还是可以做weaken的

D并不是F的必然条件

答案是B吧但这题干扰选项较多，请教高手怎么在最快的时间里选出正确答案，排除干扰选项呢

两个事物对比

support：他们在其它地方无差异

weaken：除了原文列出的因素外，还有其它未提及的因素造成了他们对比不当

我怎么理解的题目意思根lz不一样呢？
题目的意思就是事故数的比较，是o公司的事故数比p公司的少啊，而不是人数比较阿？请nn指点，是我理解错了？
还有关于d,就是说o公司的事故数都集中到几个人头上了，那是不是可以理解为这几个人发生事故的可能性大，而其他人发生事故的可能性小？
所以无法削弱？这个公司员工发生事故可能性的大小是怎么看得？有没有个数学表达式可以说明？
晕了，请nn指点

我也认为比较的是事故数。
