According to the TristateTransportation Authority, making certain improvements to the main commuter railline would increase ridership dramatically. The authority plans to finance these improvements over the course of fiveyears by raising automobile tolls on the two highway bridges along the routethe rail line serves. Although theproposed improvements are indeed needed, the authority's plan for securing thenecessary funds should be rejected because it would unfairly force drivers toabsorb the entire cost of something from which they receive no benefit.
Authority认为，想要增加ridership必须对主要的铁路线进行改进。他们想通过这样的方式积累资金：在5年里增加铁路沿线公路桥的过桥费。虽然改进是必须的，但是他们这种积累资金的方式很有可能会被拒绝，因为司机们需要为他们享受不到的好处支付金钱。
文章推理：增加过桥费，可以积累资金，但是积累资金计划会失败因为司机不愿意支付享受不到的好处
Which of the following, if true,would cast the most doubt on the effectiveness of theauthority's plan to finance the proposed improvements by increasing bridgetolls?
(A) Before the authority increasestolls on any of the area bridges, it is required by law to hold public hearingsat which objections to the proposed increase can be raised.
只是简单重复原文的前提，计划可能会遭到拒绝，但是并不代表没有效，使是否可以实行的问题。非常具有迷惑性
(B) Whenever bridge tolls areincreased, the authority must pay a private contractor to adjust the automatedtoll-collecting machines.
(C) Between the time a proposedtoll increase is announced and the time the increase is actually put intoeffect, many commuters buy more tokens than usual to postpone the effects ofthe increase.
只能起到postpone的作用 推迟了还是可能会征收高的过路费 无削弱作用
(D) When tolls were last increasedon the two bridges in question, almost 20 percent of the regular commutertraffic switched to a slightly longer alternative route that has since beenimproved.
正确，20%都选择不再走收费的路，因此政府也就筹不到钱
(E) The chairman of the authorityis a member of the Tristate Automobile Club that has registered strongopposition to the proposed toll increase.
一个人反对对有效性没有作用
B选项说政府要花钱 那么项目的目的就是筹钱，那么不是也会减少能筹到的钱吗 ？？？
D中20%不走，那么还有80%的钱可以筹的到，但是确实也是减少了部分能筹到的钱
两个都是减少能筹到的钱，为什么选D不选B呢？？？
有高人指教下吗
