GWD6-Q33:
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 Metroville 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.
正确答案为：D
Which of the following, if true, provides the strongest grounds for the officials’ prediction? 这句话问的是什么意思啊？是不是最大程度的支持官方的预测？如果是的话，我感觉也应该选A啊，D我感觉是削弱呢。
忽然想明白了..
因为现在是sparsely used所以增加了班次以后就加大了ridership
被offpeak干扰了一下，被常识误导了
