Crowding on Mooreville's subway frequently leads to delays, because it is difficult for passengers to exit from the trains. Subway ridership is projected to increase by 20 percent over the next 10 years. The Mooreville Transit Authority plans to increase the number of daily train trips by only 5 percent over the same period. Officials predict that this increase is sufficient to ensure that the incidence of delays due to crowding does not increase.
Which of the following, if true, provides the strongest grounds for the officials' prediction?
(A)By changing maintenance schedules, the Transit Authority can achieve the 5 percent increase in train trips without purchasing any new subway cars.
(B)The Transit Authority also plans a 5 percent increase in the number of bus trips on routes that connect to subways.
(C)For most commuters who use the subway system, there is no practical alternative public transportation available.
(D) Most of the projected increase in ridership is expected to occur in off-peak hours when trains are now sparsely used.
(E) The 5 percent increase in the number of train trips can be achieved without an equal increase in Transit Authority operational costs.
题目分析：原文比较简单，说虽然增加的地铁少增加的乘客多，但是不会造成拥挤。问支持。A说改变维护计划，当局能让trip增加，而不增加新的cars，增加5%，有点杯水车薪，不像支持。B当局增加bus，增加bus乘客就会分流吗？发散性选项，杀。C对于乘客来说，没有别的交通方式，那乘客那么多，还只能做地铁，那就拥挤了，不像支持。D说增加的那些乘客主要是非高峰的时候坐地铁，那就不会拥挤了，支持，留着。E说不增加成本的情况下可以增加5%的trip，和A错误原因类似，杀。
