18.         Opponents of laws that require automobile drivers and passengers to wear seat belts argue that in a free society people have the right to take risks as long as the people do not harm others as a result of taking the risks. As a result, they conclude that it should be each person's decision whether or not to wear a seat belt. .

      Which of the following, if true, most seriously weakens the conclusion drawn above? 

(A)     Many new cars are built with seat belts that automatically fasten when someone sits in the front seat.

(D)         The rate of automobile fatalities in states that do not have mandatory seat-belt laws is greater than the rate of fatalities in states that do have such laws.

(E)          In automobile accidents, a greater number of passengers who do not wear seat belts are injured than are passengers who do wear seat belts.

你们选择什么呢？ 我选择了d, 但答案不是！我不能理解！！

(B)          Automobile insurance rates for all automobile owners are higher because of the need to pay for the increased injuries or deaths of people not wearing seat belts.

B is right b/c those risk takers are hurting others financially.

D is wrong b/c it doesn't give enough information.

确实是好老的题啊。。。。

就是，既然损人利己了，就得接受法律的管教

题目是说不损害别人的利益下可以take risk,但是如果不用安全带,导致司机多交了保险费,算是损害的司机的利益.
