Critical Reasoning

试题详情

题目:

For similar cars and drivers, automobile insurance for collision damage has always cost more in Greatport than in Fairmont.  Police studies, however, show that cars owned by Greatport residents are, on average, slightly less likely to be involved in a collision than cars in Fairmont.  Clearly, therefore, insurance companies are making a greater profit on collision-damage insurance in Greatport than in Fairmont.
 
Which of the following is an assumption on which the argument depends?

选项:

A、Repairing typical collision damage does not cost more in Greatport than in Fairmont.
B、There are no more motorists in Greatport than in Fairmont.
C、Greatport residents who have been in a collision are more likely to report it to their insurance company than Fairmont residents are.
D、Fairmont and Greatport are the cities with the highest collision-damage insurance rates.
E、The insurance companies were already aware of the difference in the likelihood of collisions before the publication of the police reports.

答案:

A

提问:

在AB里面选了B。如果G的车辆总数比F多,即便G发生事故的几率小也不能说明事故总量比F小。感觉A和B结合起来才是对的。。。

提问:

老英您好, 且不看这题的答案,之前做了好几次,请看下C选项是无关还是削弱,在英文网上看过很多解释,好像各执一词,由于问题是关于假设前提,所以更倾向于说反了。。 请您解释一下,谢谢!!
