今日练习题为逻辑题，题目如下：
In countries where automobile insurance includes compensation for whiplash injuries sustained in automobile accidents, reports of having suffered such injuries are twice as frequent as they are in countries where whiplash is not covered. Some commentators have argued, correctly, that since there is presently no objective test for whiplash, spurious reports of whiplash injuries cannot be readily identified. These commentators are, however, wrong to draw the further conclusion that in the countries with the higher rates of reported whiplash injuries, half of the reported cases are spurious: clearly, in countries where automobile insurance does not include compensation for whiplash, people often have little incentive to report whiplash injuries that they actually have suffered.
In the argument given, the two boldfaced portions play which of the following roles?
AThe first is evidence that has been used to support a conclusion that the argument criticizes; the second is that conclusion.
BThe first is evidence that has been used to support a conclusion that the argument criticizes; the second is the position that the argument defends.
CThe first is a claim that has been used to support a conclusion that the argument accepts; the second is the position that the argument defends.
DThe first is an intermediate conclusion that has been used to support a conclusion that the argument defends; the second is the position that the argument opposes.
EThe first presents a claim that is disputed in the argument; the second is a conclusion that has been drawn on the basis of that claim.
正确答案：
E
题干分析：
在车辆保险会补偿事故中的whiplash injuries的国家，对这种injuries的理赔申请比不补偿的国家多两倍。有些评论者就说，既然现在没有一个客观判定whiplash的方法，骗保的行为就很难被识别。他们的这个想法是正确的，但接下来的进一步分析就错了：他们认为在那些whiplash injuries频率更高的国家，一半的whiplash injuries都是骗保的作假案例。他们错在没有认识到这个事实：保险不补偿whiplash injuries的国家，人们就算遭受到了whiplash injuries也没有报告的动机。
选项分析：
黑脸题，分清逻辑链。
A：前者用来证明一个结论，而这个结论是作者质疑的。后者就是这个结论。如果后者确实是这个结论，从 correctly 可以看出，作者是支持这个结论的。错。
B：前者用来证明一个结论，而这个结论是作者质疑的。后者是这段话要支持的论点。题目做多了大家都会有 感觉，知道真正的重点在However 后面，这题也确实是这样，所以说第二个黑脸并不是这段话的要说明的中 心论点。错。
C：前者证明了一个作者接受的结论，后者是这段话要支持的论点。和B一样，还是错。
D：前者是一个中间结论，用来证明作者要支持的主论点;后者是这段话要反对的论点。一样的，后一个黑脸， 作者都说了correctly 了，不大可能是反对，错。
E：前者提出了一个有争议的话题，后者是以这个话题为基础得出的一个结论。正确。
