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 identifi ed.
Nevertheless, these facts do not warrant the
conclusion 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?
(A) The fi rst is a claim that the argument disputes;
the second is a conclusion that has been based
on that claim.
(B) The fi rst is a claim that has been used to
support a conclusion that the argument accepts;
the second is that conclusion.
(C) The fi rst is evidence that has been used to
support a conclusion for which the argument
provides further evidence; the second is the
main conclusion of the argument.
(D) The fi rst is a fi nding whose implications are at
issue in the argument; the second is a claim
presented in order to argue against deriving
certain implications from that fi nding.
(E) The fi rst is a fi nding whose accuracy is evaluated
in the argument; the second is evidence
presented to establish that the fi nding is
accurate.

不明白D是什么意思
白痴的问一句，什么叫at issue
D说第二句是用来反对从第一个finding里得出implications 可是我觉得第一句和第二句话表达的是一个意思啊，第二个怎么会是反对第一个呢？
第一句说有规定对w赔偿的城市，report的多第二个事说在没有包括这个赔偿的国家里，人们很少去report
这两个明明是一个意思啊我真的不明白这两句之间的关系，求指教！！！
