[問題]OG 157

[fender]

157. 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.






答案是（B）我沒問題
可是OG解答說D和E有support，我實在看不出來
我看過傷咖和CD發現大家都沒有在討論這一題
一定是我讀到暈頭了
所以才連這麼簡單的題目都想不透
可否請大牛們指點一下
謝謝

不知道是不是對的，但我的理解是這樣：

題目的conclusion明顯是Therefore, employees of Company O are less likely to have job-related accidents than are employees of Company P.

A) lost more time at work與題目的conclusion無關，刪除
B) 因為計算job-related accidents的標準不同，所以公司的測量結果無法進行平等的比較，這樣題目的conclusion就無法成立，weaken
C) 雖然我覺得容易生病並不代表容易出事，但C選項成立的話也是Strengthen conclusion，刪除
D) 選項的Several employees是模糊字眼，無法得知several是多少，也不知道P公司與O公司的員工人數多寡，所以無法weaken conclusion，刪除
E) O公司的主要job-related accidents與題目的conclusion無關，刪除
