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.

 

答案为B

请问E为什么错？？选项E陈述了other factors,不是正好weaken conclusion吗？？

involved in a single machine与工作事故率的大小没有关系吧?

B是真正的other factors P鉴定为工作事故的范围比O大

题目要的是能削弱O比P事故少这个结论的选项

这题到底是啥意思啊，不是很明白。。。更多的事故类型能说明P更容易出事故吗？
D为啥不对。。。

顶一下。。

你只要找到选项能否定最后一句话：Therefore, employees of Company O are less likely to have job-related accidents than are employees of Company P. 就行了。否定后是说：employees of Company P are less likely to have job-related accidents than are employees of Company O。因为B选项说P公司能考虑到可能发生的更大的事故范围，所以有更小的几率发生事故。符合否定后的说法。

Ｄ選項

職災事件總數＝單位量Ｘ單位(人)
Ｐ公司:大＝小Ｘ多
Ｏ公司:小＝大Ｘ少        
更加證實Ｐ比較危險
因為受傷人數比較多
