[求助]不知哪来的题目~~

In Argonia the average rate drivers pay for car accident insurance is regulated to allow insurance companies to make a reasonable profit. Under the regulations, the rate any individual driver pays never depends on the actual distance driven by that driver each year. Therefore, Argonians who drive less than average partially subsidize the insurance of those who drive more than average.

The conclusion above would be properly drawn if it were also true that in Argonia.

（A）the average accident insurance rate for all drivers rises whenever a substantial number of new drivers buy insurance.

（B）           the average cost to insurance companies of insuring drivers who drive less than the annual average is less than the average cost of insuring drivers who drive more than the annual average.

（C）           the lower the age of driver, the higher the insurance rate paid by the driver.

（D）           Insurance company profits would rise substantially if drivers were classified in terms of the actual number of miles the drive each year.

（E）            drivers who have caused insurance companies to pay costly claims generally pay insurance rates that are equal to or lower than those paid by other drivers.

题目说无论每轮每年司机驾驶的距离是多少，付的保费都一样。所以开得少的司机相当于资助了驾驶里程多的司机。

从这个能找出其中的缺陷，保费一样，开得少的资助了开得多的。也就是说开得少的从保险公司得到的要比开的多的少，并且少于平均数，也就是自己得到赔偿要比平均值至少，少的部分给了开得多的司机。
