一道逻辑题，对A 很是疑惑

jm2003222

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 _______.  
 most people in favor of expanding the rail system reported less congestion during their highway commute as the primary benefit they would experience  

 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  

 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  

 expanding the commuter rail system will require the construction of dozens of miles of new railbed  

 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  
请问A到底说的是什么，感觉读不出什么意思，哪里说出原因了？？
我读成的是大多数赞成这个的人报道了少的这个交通问题作为好处他们将要经历的，感觉不是地球人说的话…………

鄙人的逻辑分析如下：

最近民调发现，80%的人支持扩建；然而民调结果显示，即使扩建也不能缓解堵塞，A.因为在支持扩建的人中，大多数把交通不堵塞列为他们幸福指数的第一位。

B选项是说的少数派，无关；C选项说的是开车拥堵时间上升，与highway无关；D选项说的是建铁路要花钱，无关；E选项说的是建铁路对某些人有利。
B.C.D.E没一个能说明为什么扩建不能缓解拥堵，而A则隐晦的提到了，所以选她。

样本代表性问题吧。因为response的人都是喜欢公共交通的人，所以即使expand了，也还是那批喜欢的人坐，不喜欢的人依然开车，那么高速公路还是拥挤的
