Industrail accidents are more common when some of the people in safety-sensitive jobs have drinking problems than when none do. Since even after treatment, people who have had drinking problems are somewhat more likely than other people to have drinking problems in the future, any employer trying to reduce the risk of accidents should bar anyone who has ever been treated for a drinking problem from holding a safety-sensitive job.
Which of the following , if true, most seriously undermines the arguement above?
a.some companies place employees who are being treated for drinking problems in residential programs and allow them several weeks of paid sick leave.
b.many accidents in the workplace are the result of errors by employees who do not hold safety-sensitive jobs.
c.workers who would permanently lose their jobs if they sought treatment for a drinking problem try instead to conceal their problem and continue working for as long as possible.
d. people who hold sagety-sensitive jobs are subject to stresses that can exacerbate any personal problems they may have, including drinking problems.
e.some industral accidents are caused by equipment failure rather than by employee error.
新东方答案C。
怎么会是C呢？想不通。
第一眼我也认为是B。主要是我的阅读还不过关。仔细阅读和理解题意后，可以看到：
题中的Fact是：有DrinkingProblem的人在safety-sensitive岗位上，事故就会多。
题目中的推理是：由于过去有DrinkingProblem的人更容易重新发生DrinkingProblem，因此要减少和避免这些人进入Safety-sensitive岗位
选项C的意思是：如果工人们由于接受治疗而可能失去工作，他们就会掩盖真相不接受治疗。
继续向前和向后推理，意思是如果采取限制政策，工人们会产生掩盖真相的对策，反而使得情况更加危险。
