12.Sleep deprivation is a known cause of workplace

　　error， and many physicians frequently go without

　　sleep for periods of 24 hours or more. However， few

　　of these physicians have， in the course of a routine

　　examination by a peer， been diagnosed with sleep

　　deprivation.So there is little cause for concern that

　　habitual sleep deprivation will cause widespread

　　physician error.

　　The answer to which of the following questions

　　would be most helpful in evaluating the argument？

　　（A）Do physicians who have been diagnosed with

　　sleep disorders also show signs of other ills not

　　related to sleep deprivation？

　　（B）Is the ability to recognize the symptoms of sleep

　　deprivation in others significantly impaired by

　　habitual sleep deprivation？

　　（C）Do factors other than habitual sleep deprivation

　　ever lead to errors in the workplace on the part

　　of physicians？

　　（D）Of people who have recently been treated by

　　physicians， what percentage believe that many

　　physicians have occasionally suffered from sleep

　　deprivation？

　　（E）Is the incidence of sleep deprivation higher

　　among physicians than it is among other health

　　care workers？





答案是B为什么不是C啊~~~~求解释！！

B 的意思是是否这种经常性的睡眠剥夺使得睡眠缺乏的症状不明显了，如果答案是是，那么原文中的结论就将推翻，因为已经无法分辨与其他正常人的区别，所以无法比较，而C与原文并无很大关系

就是说这道题要选的是能够影响argue成立与否的相关性最大的问题，无所谓支持还是削弱。是这样理解么？
