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 of 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 railroads. 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. 为什么是A呢 expansion of the rail system不是能ease congestion on highway么？
求问：C为什么不对呢？ C说：一天两次的高速公路高峰堵车时间在过去20年里，由原来的一个小时延长到了一个半小时。这不就是说：congestion 没有缓解，反而增加了么？This is my explanation: (The commuters in cars who don’t switch to railway will confront the congestions, even longer time.) 难道这个是因为twice congestion是无关选项？
