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?

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.

正确答案选A, A 为NOT WEAKEN 模式，我觉得E 也有道理，正因为E：保险公司注意到了两者的不同，才采取措施多保Greatport，而不是Fairmont，所以才能获利！请指正！
