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?
commentators提出了两点看法:1.spurious reports of whiplash injuries cannot be readily identified.——这个结论作者认为是正确的。2.in the countries with the higher rates of reported whiplash injuries, half of the reported cases are spurious——这个结论作者认为是错误的。 其中commentators是先得出了第一个结论,然后又继续推论,得出第二个结论,所以第一个结论相对于第二个是intermediate conclusion, 第二个结论是commentator的最终conclusion,然而这个结论作者认为是错的,符合答案C
