"如果增加班次只是为了使原来的拥挤不恶化，那么其意义何在" is not the concern here at all. You should never think beyond the reasoning of the argument. For example, if the is your concern, how about building highway instead of subway? How about low gas price so that people will drive more? We are not given any information for us to make judgment on such things.
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 crowding proportionately (20% to 20%). Therefore 5% increase in trips might well mitigate the problem. mindfree！太好了 A：can achieve the 5 percent increase in train trips，怎样实现这5%的增长is not the concern here at all. B：also plans a 5 percent increase in the number of bus trips，增不增加公车is not the concern here at all. C：For most commuters who use the subway system, there is no practical alternative public transportation available.，有没有可选工公交通工具is not the concern here at all. D : E : operational costs is not the concern here at all. |
