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.
key: B
我明白为什么选B。但是对于为什么不选c,e有点犹豫。
og 解释:the relevance of the employees'sickness(choice C) can not be assessed without informationabout the links, if any, between sickness and job-related accidents.
choiceD 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 spport the conclusion.
当我看到这道题时,就是找选项符合他因导致结果。
对于c:og的意思是说sickness and job-related accidents没关系,但是其实是挺有关系的,这不是明摆着有关系吗!
对于D: og 的意思就没看明白。自己认为,既然o中有的人 had more than one job-related accident.,证明o厂其实也挺危险的,不比p差,所以消弱结论。
盼nn,xdjm解答呀,谢谢呀!:)
