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 suffi cient 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?
GWD6-Q33 GWD6-Q33: CrowdingonMooreville’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.
求这道题完整的大意和,D的解释,我看到这道题有两个量,subway, trains ,他们之间的关系怎么回事啊? 最后一句话的does not increase 是什么成分,是修饰crowding 的么,due to 是最后一句话的谓语吗?谢谢好心人的帮助!
D. Most of the projected increase in ridership is expected to occur in off-peak hours when trains are now sparsely used. 预计的乘客人数增长是发生在非高峰时段,由于现在火车已经很少作为交通工具。
GWD6-Q33 对于这道题的讨论还挺多的,但是只有mindfree大牛的以下说法让我有点明白:Here all we know is that crowding is to blame for delay. So 20%ridership, is occurs only during off-peak time, will not cause crowdingproportionately (20% to 20%). Therefore 5% increase in trips might wellmitigate the problem.
但是我认为还需要再理清一下这道题的思路。 Premise 1Crowding 导致delay,于是Subway ridership is projected to increase by 20 percent. Premise 2 MT authority 打算增加20%班次,但车辆只增加5%。 conclusionOfficials predicts 这样做就可以解决由crowding导致的delay问题。
