问题 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?
选项 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B
解析 本题通过睡眠不足的医生的同事对这些睡眠不足的医生的检查，得出了习惯性的睡眠不足不会引起工作出错的结论，因此本题结论暗含的一个假设是判断别的医生是否睡眠不足的能力会不会受自己本身就睡眠不足的影响，若受自身的影响时，则那些常规检查的结果就是不可靠的，因为缺乏睡眠的医生没有判断别人是否睡眠不足的能力；若不受自身的影响，则(B)就会支持段落中关于睡眠不足确实不是医疗事故的原因。由以上分析可知，(B)为正确答案。
