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？

另一道The bodies of dwarf individuals of mammalian
species are generally smaller in relation to those of

nondwarf individuals than are the teeth of the dwarf

individuals in relation to those of the nondwarf indi－

viduals。 Fragmentary skeletal remains of an adult

dwarf woolly mammoth were recently found。 The teeth

are three－fourths the size of the teeth of an average

adult nondwarf woolly mammoth。

The statements above， if true， most strongly support

which of the following？

（A）The body of the dwarf woolly mammoth was

less than three－fourths the size of the body of

an average adult nondwarf woolly mammoth。

（B）None of the teeth of the dwarf woolly mammoth

that were recently discovered was as large as

any of the teeth of nondwarf woolly mammoths

that have been discovered。

（C）The teeth of most adult dwarf individuals of

mammalian species are three－ fourths the size of

the teeth of the adult nondwarf individuals of

the same species。

（D）Dwarf woolly mammoths had the same number

of teeth as did nondwarf woolly mammoths。

（E）Dwarf individuals of most mammalian species

are generally no more than three－fourths the

size of the adult nondwarf individuals of those

species。

原因：医生中Sleep deprivation的人数少
结论：Sleep deprivation不大可能造成广泛事故。
可以从前提，推理过程，结论三个方面进行怀疑。调查可性度，缺觉者可能的事故率，并发症等。
A.缺觉会不会带来其他症状？无关选项。
B.对于缺觉诊断的确定性？这个是直指前提的，即怀疑survey可行度的。正确。
C.其他导致事故的因素？无关选项。
D.患者认为缺觉的医生有多少？无关选项。
E.医生的缺觉率是否高于其他工作人员？问题本身和主题无关。

句子的潜台词肯定是dwarf individuals比nondwarf individuals小，OK？
dwarf individuals与nondwarf individuals在body上的比值，小于两者在teeth上的比值。

赞，怀疑peer本身调查能力不足
