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?

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 Authoritycan 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.

The 5 percent increase in the number of train trips can be achieved without an equal increase in Transit Authority operational costs.


【申友解析】


正确答案:D


题干:M地地铁的拥挤时常导致延误,因为乘客很难下车。地铁搭乘人数在未来十年内会增长百分之二十。M地交通管理部门计划在同期只增加百分之五的运力。官方预测该计划足以保证拥挤导致延误的状况不会更严重。
题目:下面哪一项为官方预测提供了支持。
分析:由于题干中的论点和论据存在明显的不一致性,我们这里最有可能的思考方向是引入他因加强型正向逻辑。
选项A, 改变了维护周期之后,交通管理部门可以在不增加新列车的情况下提高百分之五的运力。我们不关心如何提高百分之五的运力,我们只关心提高的这百分之五的运力能不能应付百分之二十的乘客增长,无关属性!
选项B,交通管理部门同时计划在连接地铁的线路上增加百分之五的巴士运力,同样无法解决地铁线路的拥挤问题,只能方便乘客换乘。
选项C,对于大多数的地铁乘客,实际上没有其他的公交选择替代方案。该选项只会使得题干中的矛盾更显著,反向逻辑!
选项D, 乘客的增加主要出现在非高峰时期,这是一个合理引入的能解释百分之五的运力提高如何应对百分之二十的乘客增长的他因。正确!
选项E, 谈成本,无关属性。
