Poblice statistics have shown that automobile autitheft devices reduce the risk of car theft,but a statistical study of automobile theft by the automobile insurance industry claim that cars equipped with antitheft devices are,paradoxically,more likely to be stole than car that are not equipped.
which one of the following,if true,does the most to resolve the apparent paradox?
a) Owners of stolen cars almost invariably report the theft immediately to the police but tend to delay notifying their insurance company ,in the hope that the vehicle will recovered.
b) Most cars that are stolen are not equipped with antitheft devices,and most cars that are equipped with antitheft devices are not stolen.
c) The most common automobile antitheft devices are audible alarms,which typically produce ten false alarm for every actual attempted theft.
d) Automobile owners who have particularly theft-prone car and live in ares of greatest incidence of car theft are those who are most likely to have antitheft devices installed
e) Most automobile thefts are the work of professional thieves against whose efforts antitheft devices offer scant protection.
c,d,e哪一个是对的,并解为何

选D

CXD里面还有一道类似的题。我暂时找不到了。那道题的中文大意是,某税务局的几名tax collectors里,有一个collector收税比例最低,但他却是所有collectors里面业绩最好的。答案就是这个collector负责的商户都是难搞的钉子户。

CXD书里确实有解释
但之所以把题目抄到这里来,是因为在下不满足于书上的那么一点关于正确答案的解释,我还想要知道它关于错误选项为什么错的解释.
