紧急的求助一道CR 寂静题，谢谢大家了！

Cherliuiking

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?

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.    eople who hold safety-sensitive jobs are subject to stresses that can exacerbate any personal problems they may have, including drinking problems.
E.    Some industrial accidents are caused by equipment failure rather than by employee error.
这道题的答案是什么呢？我选的是C
谢谢NN

D是迷惑选项，这个题目不存在因果颠倒的问题，而D选项似乎想通过说是因为工作导致了酗酒来混淆。即使D是这样，那么也会strength题目，而非weaken，正因为从事安全性岗位的要求高，导致压力大，所以，若是有酗酒问题的话将会更加严重。那么说明更加不能录用这样的人。

open to discuss..

No connection with the question stem - Drop it

Many accidents in the workplace are the result of errors by employees who do not hold safety-sensitive jobs.
"many" does not give enough information. and i think it goes against the premise of the question - drop it

Workers who would permanently lose their jos if they sought treatment for a drinking problem try instead to conceal their problem and continue working for as long as possible.
If there is no record of any treatment of drinking problem, the employer wont bar workers from working in safety-sensetive jobs and still have the risk of accidents - keep it

People who hld safety-sentive jobs are subject to stresses that can exacerbate any personal problems they may have, including drinking problems.
This is a tricky / trap options. It says that stress can increase the risk of drinking problem (which employee already had). please see the word "exacerbate". it doesnt say that due to stress employee will start drinking. So in my opinion this option actually supports the conclusion. It gives another reason to emplyer not to put peeple with prior drinking problems on this job. Drop it

Some industrial accidents are caused by equipment failure rather than by emplyer error.
"some" doesnt give enough information - Drop it

Every fall Croton's jays migrate south.  The jays always join flocks of migrating crookbeaks with which they share the same summer and winter territories.  If a jay becomes separated from the crookbeaks it is accompanying, it wanders until it comes across another flock of crookbeaks.  Clearly, therefore, Croton's jays lack the navigational ability to find their way south on their own.

Which of the following, if true, most strengthens the argument above?

A. Croton's jays lay their eggs in the nests of crookbeaks, which breed upon completing their southern migration.

B. The three species most closely related to crookbeaks do not migrate at all.

C. In the spring, Croton's jays migrate north in the company of Tattersall warblers.

D. Species other than Croton's jays occasionally accompany flocks of migrating crookbeaks.

E. In the spring, crookbeaks migrate north before Croton's jays do.

reduce the risk => bar treated person

if you do not know he was/is being treated when hiring him/her, how to reduce the risk? therefore, the argument is weakened
