标题: 菜鸟的问题GDW-1-Q7

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.

为什么是选a？

evidence:G的保险费比F高；G发生的车祸比F少

conclusion:G的保险公司利润比F高

assumption：G的修车费不比F高，因为如果修理费高的话，那么G的保险公司赔偿的数额就高，所得利润就会减少。取非就能验证了。
