37. Car owners who inflate their tires properly can substantially boost their vehicles’ fuel efficiency, since the increase in car-road friction can waste up to five percent of car fuel by underinflation.
(A) Car owners who inflate their tires properly can substantially boost their vehicles’ fuel efficiency, since the increase in car-road friction can waste up to five percent of car fuel by underinflation.
(B) Because the underinflation of tires can waste up to five percent of a car’s fuel by increasing car-road friction, car owners can substantially boost their vehicles’ fuel efficiency by properly inflating the tires.
(C) Their vehicles’ fuel efficiency is substantially boosted by car owners through the proper inflation of tires that, when underinflated, can waste up to five percent of car fuel by an increase in car-road friction.
(D) The proper inflation of tires by car owners, due to the fact that underinflation can waste up to five percent of a car’s fuel by the increase of car-road friction, can substantially boost their fuel efficiency.
(E) Because up to five percent of a car’s fuel are wasted through the increases in car-road friction when the tires are underinflated, car owners properly inflating tires can substantially boost their fuel efficiency.

答案为B，A错在哪里？

个人观点：A中by underinflation修饰不好，按照就近修饰原则，修饰car fuel ，但是逻辑不对。

此外，我觉得A表达的逻辑关系没有B表达的清晰

在表示因果关系的句子里，一般用because，而且是在句首，不用since

以下是引用深海的小美人鱼在2003-12-31 4:54:00的发言：

又学到一点

谨记小鱼教诲: because 引导原因状语放与句首比since好.

如果不看B选项,觉得A表达的还可以, 但是一看到B的原因状语从句, 就再也忍耐不住淘汰A的冲动了, the underinflation of tires can waste up to five percent of a car’s fuel by increasing car-road friction, 这里清楚的表达出"轮胎充气不足->增加了车与路面的摩擦-> 费油"; 相对的A答案the increase in car-road friction can waste up to five percent of car fuel by underinflation.中的by underinflation离increase...太远了, 没有办法很清楚的表达出"充气不足导致摩擦增大"这种关系, 正像dreadpower说得, 好像在修饰fuel. 比较A,B两个, 不免会问: 到底是"增大摩擦通过充气不足来费油"还是"充气不足通过增大摩擦来费油"? 呵呵, 后者好些!

相當贊同！
我覺得 since 最大的問題是他也可以表示 '自從'
雖然這裡的時態可議.
而如果看到 since + Noun 就知道since當介係詞用, 此時一定是表示自從而非因為了.
