10. Traffic safety experts predict that the installation of newly designed air bags in all cars in the LACE w:st="on">United StatesLACE> would reduce the average number of fatalities per traffic accident by 30 percent. In order to save lives, the Department of Transportation (DOT) is considering requiring automobile manufacturers to install air bags of this design in all cars produced after 1998.

Which of the following, if true, represents the strongest challenge to the DOT’s proposal?

(A) Air bags of the new design are more given to being inadvertently triggered, an occurrence that can sometimes result in fatal traffic accidents.

(B) The DOT is planning to require automobile manufacturers to produce these air bags according to very strict specifications.

(C) After installing air bags in new cars, automobile manufacturers will experience an increase in sales.

(D) The proposed air bag installation program will adversely affect the resale of cars manufactured prior to 1998.（A）

(E) As production costs increase, the profits of many domestic automobile dealers show a marked decrease.

我选的C 开始就在A C 之间犹豫,最后觉得DOT的计划是安装在1998年后生产的车,那么就想到时间的对比,98年前的车销售会受影响,所以行不通,A 好象直接反对了前提 说装置本身不安全,这样可以吗?

请大家指教

注意would reduce the average number of fatalities per traffic accident by 30 percent，每次交通事故中的死亡率将减少30%，是相对值，每次交通事故的死亡率和交通事故总量是没有关系的，C不对~~
