1.         GWD-30-Q19

Industrial 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 argument above?

1. Some companies place employees who are being treated for drinking problems in residential programs and allow them several weeks of paid sick leave.
2. Many accidents in the workplace are the result of errors by employees who do not hold safety-sensitive jobs.
3. 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.
4. People who hold safety-sensitive jobs are subject to stresses that can exacerbate any personal problems they may have, including drinking problems.
5. Some industrial accidents are caused by equipment failure rather than by employee error.

答案是c，为什么D不可以呢？  D不是因果颠倒吗？是先hold safety-sensitive jobs，后才会酗酒啊

论据：喝酒的出事多

结论：要想防止事故，不让喝酒的从事安全敏感工作。

削弱：安全敏感工作出不了事，出事的都是非安全敏感工作

People who hold safety-sensitive jobs are subject to stresses that can exacerbate any personal problems they may have, including drinking problems.

从事安全敏感工作的人工作压力大，可能激发他们的坏毛病，包括喝酒。无关

B，你的答案可能有误，相信自己的分析，不要相信标准答案

我弄错了，答案是C，我现在觉得答案是对的，答案说bar anyone who has ever been treated for a drinking problem from holding a safety-sensitive job.就可以reduce the risk of accidents，然后C说如果这样做了很多有酗酒迹象的人就会隐藏他们的问题，削弱了结论。 我觉得B是无关的，全篇都在谈论关于sensitive job.不涉及nonseneitive job啊？

请指教~~

结论是要想减少风险，就禁止酒鬼干 safety-sensitive job

我觉得“隐藏酗酒习惯”的确是他因，但没有落到结论上

而B恰恰说 safety-sensitive job出不了事

个人想法：ls继续

Many accidents in the workplace are the result of errors by employees who do not hold safety-sensitive jobs.

它既没有说明sensitive job出不了事，也没有说明是否酗酒有什么关系.?

Many accidents in the workplace are the result of errors by employees who do not hold safety-sensitive jobs.

我尝试翻译一下：

许多事故是由于从事“非安全敏感工作的工人”引起的。

正好削弱结论：

要安全，就禁止酗酒的人从事“安全敏感工作”。

要安全，酗酒者不能做A工作

削弱：

B工作才不安全。
