请教各位大牛里一道GWD里的题～

是这样的～是gwd第3份里一道逻辑～

which of the following, if true, most logically completes the passage?

A recent poll found that over 80 percent of the residents of Nalmed Province favored a massive expansion of the commuter rail system as a means of significantly easing congestion on the province's highways and were willing to help pay for the expansion of the rail system, if successfully completed, would be unlikely to achieve its goal of easing congestion, because_______________.
a. most people in favor of expanding the rail system reported less congestion during their highway commute as the primary benefit they would experience
b. of the less than 20 percent of residents not counted as favoring the expansion, about half claimed to have no opinion one way or the other
c. the twice daily periods of peak congestion caused by people commuting in cars have grown from about an hour each to almost two and a half hours each in the past 20 years
d. expanding the commuter rail system will require the construction of dozens of miles of new railbed
e. the proposed expansion to the commuter rail system will make it possible for some people who both live and work at suburban locations to commute by rail

答案是选A。为啥说 希望能够拓展铁路的人被报告说是他们的高速公路不堵了，那么他们原本想要得到的益处就得到了么？这样子的话不是刚好能够说明（加强）这个提案的可行性呀？

表示这个思路没打开阿～有谁来提点提点？

谢谢哈～

这题我一开始看下来，没一个着边的。。。
后来看了别人的解释。。。恍然大悟
expansion of the commuter rail system as a means of significantly easing congestion on the province’s highways
A. most people in favor of expanding the rail system reported less congestion during their highway commute as the primary benefit they would experience
即那些人之所以支持 expanding the rail system, 是觉得这么一来别人就会去坐rail了，那自己在highway开车就不赌了，大家都等着别人去坐rail, 自己其实并不会去，照样开车。。。。
