Which of the following most logically completes the argument?
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 reducing 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 contain an indication that expansion of the rail system, if successfully completed, might be unlikely to achieve its goal of reducing 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-dairy periods of peak congestion caused by people commuting in cars have grown, over the past 20 years, from about an hour each to about two hours each
expanding the commuter rail system will require the construction of dozens of miles of new bed
the proposed expansion would make commuting by rail possible for many people who Eve in one suburb and work in a different suburb of the province's main city
调查发现80%的人愿意支持并且通过出钱交税的方式让铁路扩建来减少高速拥堵。但是如果铁路扩建执行了可能也没办法达到目的,因为
choice a, 大多数支持扩建的人表示期待他们在高速上的拥堵会减少。correct,这些80%支持的人本身就是使用高速公路的人,即便铁路扩张这些80%的支持者也不太会去用铁路,所以高速路还是拥堵
choice e, 铁路扩建会便利在住在一个区但是要去另一个工作的人。irrelevant
