标题: [讨论] GWD-9-24
这道题答案没有问题，是排除法得到的，总觉得选项A的推理不足以作为assumption，但没有更好的选项，不知大家是怎么想的？

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?

Repairing typical collision damage does not cost more in Greatport than in Fairmont.

There are no more motorists in Greatport than in Fairmont.

Greatport residents who have been in a collision are more likely to report it to their insurance company than Fairmont residents are.

Fairmont and Greatport are the cities with the highest collision-damage insurance rates.

The insurance companies were already aware of the difference in the likelihood of collisions before the publication of the police reports.

利润=收入-事故数*事故所赔额

前提说事故数少，结论说利润就高，那么得假设事故所赔偿金额少才行。

为什么不能选B呢。。

做的时候第一反映是A，可是仔细一想保险费和修理费有关么？所以就排了。。

而B，说开车的人要一样多。取非，如果G的人数比F多，那么即使LESS LIKELY，保险费也可能高啊。。。

搜索了一下只有一个人问过。。。是不是很白痴的问题啊。。。还有十几天就要考了。。。

B取非，原结论并没有削弱：如果G的人数比F多，事故率又比F低，因此G的利润依然可能比F高；

对A取非：G的修理费比F高，按照利润=保险费—赔偿金/修理费等事故处理成本，G的利润F低，原结论削弱，所以A是正确选项。

同意楼上的观点。assumption题不外乎架桥和not+weaken两招.
