GWD-6-33 -->携隐修改标题（ＧＷＤ　６－３３）

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 nexst 10 years. The Metroville Transit Authority plans to increase the number of daily train trips by only 5 percent over the same period. Officials predicted that this increase is sufficient to ensure that the incidence of delays due to crowding does not increase.

Which of the following, if ture, 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 Project increase in ridership is expected to occur in off-peak hours shen 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.
