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
思路：调查中有80%的人愿意为铁路系统的扩张缴纳更多的税，目的是使告诉没那么拥堵；但这个调查结果也同时说明了铁路扩张并不会减轻高速拥堵状况，因为——这些人的想法都是铁路扩张后别人就会去使用铁路，自己使用高速路就会没那么拥堵了。
我有关注到一个点：题目有句话是the poll results contain an indication that ，那么原因也往这个调查中去找。
