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

GWD的题一般以前都讨论过的，建议多搜索一下

If choice A is true that most people regard their primary benefit as the less congestion during their highway commute, then still many people will drive to work even after the rail system is complete, therefore the expansion would be unlikely to achieve its goal of easing congestion.
