Q33:                    

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

   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

没思路,请指教.

难道是因为"A指出可能有其他因素导致道路拥挤"?

A表明赞成新建铁路的并不是为了缓解HIGHWAY的交通拥挤,而是因为享受到了RAILWAY的不拥挤;

相反这些赞成者都表示他们在HIGHWAY上并未感到拥挤,因此,他们选择RAILWAY并非因为HIGHWAY拥挤
