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 through an increase in their taxes.  Nevertheless, the poll results indicate that expansion of the rail system, if successfully completed, would be unlikely to achieve its goal of easing congestion, because _______.

1. most people in favor of expanding the rail system reported less congestion during their highway commute as the primary benefit they would experience
2. 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
3. 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
4. expanding the commuter rail system will require the construction of dozens of miles of new railbed
5. 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

Answer: A

可以排除BCDE.  但是A是说多数主张扩铁路的人报告说公路上不堵车是他们会经历的最大好处.   这为什么会影响公路不堵车的实现呢?   是不是我理解错a的意思了?  请教NN.

Thank you very much!

我有个想法，因为ＭＯＳＴ　ＯＦ这些８０％的人投资是因为ＲＡＩＬ　会降低ＨＩＧＨＷＡＹ的拥挤，他们会受益，说明他们中很多不会改做ＲＡＩＬ，而继续使用ＨＩＧＨＷＡＹ，说明ＨＩＧＨＷＡＹ上的这些人不知醒悟，那就只有继续堵起了哟

结论表示
        : 尽管如此, 这项鐡路系统调查结果将不太可能达到它们减少阻塞的目标, 找原因: A选表示
        因为大多数人在使用高速公路时, 是希望其它人使用鐡路(这是很自私的想法, 也就是大多数人是希望自己在使用高速公路不会受到阻塞的困扰)所以有了这个原因也就达成前句结论的推理了.

请指教
