25.   olice statistics have shown that automobile antitheft devices reduce the risk of car theft, but a statistical study of automobile theft by the automobile insurance industry claims that cars equipped with antitheft devices are, paradoxically, more likely to be stolen than cars that are not so 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 be 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 alarms for every actual attempted theft.


(D) Automobile owners who have particularly theft-prone cars and live in areas 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.



为什么选D?一点都想不通。

这道题我也不太明白,是不是可以这么理解,D答案告诉我们那些拥有容易发生盗窃的车辆又住在容易发生车辆盗窃事件的地区的车主更喜欢装上反盗窃装置,这可不可以看作对文中第一句话的支持,也就是通常对P的支持,因为这题要求对非P进行解决,所以可以理解成对P的支持就是对非P的解决了


不知道我的理解对不对,大家可以讨论一下

STIMULUS MATERIAL的大意:


是来自警局的数据表明汽车防盗装置降低了汽车被盗窃的危险;但是来自保险公司的数据却表明装有防盗装置的汽车比没有装防盗装置的汽车更容易被窃。


然后问哪一个选项解释了这个看似矛盾的“矛盾”。


我认为STIMULUS MATERIAL里的两个STATEMENT其实根本不矛盾,一个是说汽车防盗装置降低盗窃率,另一个是说在失窃的车里装有防盗装置的车多于没有装防盗装置的。这个“不矛盾”通过具体例子能看得更清楚:某年某地由于汽车防盗装置的应用只有100辆车被盗,被盗率比去年下降20%;而在这100辆车里80辆是装有防盗装置的车。之所以会有后种情况出现是:EITHER被盗车辆本身大多属于“高危车群” ,就是属于比较受盗车贼青睐的品牌或车型;OR是因为车主住在盗车行为比较猖獗的社区,这两种情况下车主一般都会装汽车防盗装置。D完美地给出这个解释。注意这里的关健是:装有防盗装置并不是车子被盗的原因,而是被盗车子本身比其它车子被盗可能性高的一个表现。


希望讲清楚了。

不用谢,也不是大牛。

也在为逻辑题头疼,希望大家能互相帮助一起进步。

我觉得你的思路很清晰,把一个问题说得很清楚


我刚刚才接触LSAT,还需要很多时间来提高,希望大家能共同进步
