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.
果因推理题
前提：去年，O公司员工的工作事故比P公司员工少（果）
结论：O公司员工比P公司员工更不可能发生工作事故（因）
果因推理题求削弱：CQ1：说明结果问题 CQ2：因果联系问题
B选项为CQ1，是P公司比Q公司考虑更多类型的工作事故，导致O公司员工的工作事故比P公司员工少，而不是因为O公司员工比P公司员工更不可能发生工作事故。
