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.

WHY D?~

Conclusion: The 5% increase in train trips will be suffiecient to handle the 20% increase in ridership.

How is it possible that just 5% increase in the train trips will handle 20% increased ridership??

Think about a situation where the ridership will increae during a period of the day when the currently running trains already run with fewer number of riders then some of the new riders can be accomodated in the currently running trains..The remaining new riders can be accomodated in the new 5% incresed train trips..D says exactly this and hence the answer..Hope that helps..

yes D 5% will compensate 20% means 15% contributed to the non used part so D is ok

Yes agree with D. as it strongly supports the officials predictions.

every option other than D is out of scope. That itself should have left you with D.
