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 _______.  
 
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  

请教大牛，答案为什么选A？

这道题...
在我读了NNN遍，反复思考之后得出以下想法
提干：一个调查，80%人支持扩建铁路系统作为缓解高速公路拥挤的方法，并且愿意帮助承担费用。
结论：但是这个调查的结果显示，如果铁路系统成功建成后也不会减少高速公路的拥堵

现在要找原因，A选项意思说 大多数支持扩建的人表示，希望更少的高速公路拥挤会成为他们（大多数支持扩建的人）的福利

就是说那些支持扩建的人并不会去乘RS，仍旧会选择HS，他们是希望建完之后人家去用

所以就解释了原因
