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?
The employees of Company P lost more time at work due to job-related accidents than did the employees of Company O.
Company P considered more types of accidents to be job-related than did Company O.
The employees of Company P were sick more often than were the employees of Company O.
Several employees of Company O each had more than one job-related accident.
The majority of job-related accidents at Company O involved a single machine.
为什么不选c：因为从O had fewer job-related accidents last year到O are less likely to have job-related accidents这个逻辑在不给b条件前是没有漏洞的，譬如他一天读一本书，她一天读三本书，所以她读书效率比他高肯定是对的，不能因为说他那段时间生病了所以削弱她效率更高这件事，这可以是解释的原因，但绝对不是对结论的削弱，因为结论讨论的并不是他们的aptitude，结论讨论的也是一种现象。
