1.        GWD-30-Q28, why the answer is D?!

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.  Presently, no objective test for whiplash exists, so it is true that spurious reports of whiplash injuries cannot be readily identified.  Nevertheless, these facts do not warrant a conclusion that has been drawn by some commentators:  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?

1. The first is a claim that the argument disputes; the second is a conclusion that has been based on that claim.
2. The first is claim that has been used to support a position that the argument accepts; the second is a position that the argument rejects.
3. The first is a finding whose accuracy is evaluated in the argument; the second is the judgment reached by the argument concerning the accuracy of the finding.
4. The first is a finding whose implications are at issue in the argument; the second is the judgment reached by the argument concerning one alleged implication.

我也选c，谁来帮帮忙？ 谢谢

D就对了,我还想了老半天"为什么D错了",原来是看错答案了.

有accuracy的都错,题目中第一句话陈述的是一个事实,正确率100%,后面没有对其真假作判断,只不过说"以此为据推得另一个结论是不合适的".

谁能不能解释下这段话到底要说什么？

作者是认为凭这些事实不能证明虚假报告？那最后都是评论者的结论，作者并没有做任何解释吗?
