问prep-1-55

According to the Tristate Transportation Authority, making certain improvements to the main commuter rail line would increase ridership dramatically.  The authority plans to finance these improvements over the course of five years by raising automobile tolls on the two highway bridges along the route the rail line serves.  Although the proposed improvements are indeed needed, the authority's plan for securing the necessary funds should be rejected because it would unfairly force drivers to absorb the entire cost of something from which they receive no benefit.

Which of the following, if true, would cast the most doubt on the effectiveness of the authority's plan to finance the proposed improvements by increasing bridge tolls?

(A) Before the authority increases tolls on any of the area bridges, it is required by law to hold public hearings at which objections to the proposed increase can be raised.

(B) Whenever bridge tolls are increased, the authority must pay a private contractor to adjust the automated toll-collecting machines.

(C) Between the time a proposed toll increase is announced and the time the increase is actually put into effect, many commuters buy more tokens than usual to postpone the effects of the increase.

(D) When tolls were last increased on the two bridges in question, almost 20 percent of the regular commuter traffic switched to a slightly longer alternative route that has since been improved.

(E) The chairman of the authority is a member of the Tristate Automobile Club that has registered strong opposition to the proposed toll increase.

答案是d实在想不通。我选的c，为什么不对呢？

这题，我也有很大的疑问。主要是我没看明白题目问的到底是削弱还是支持，因为C和D正好是两个相反的选项。怪我阅读太差，请NN帮我解释一下，这道问的到底是什么？

我理解的是：下面哪个对新建的项目的有效性提出质疑？如果是这样不是应该是weaken 题，说明不因该建bridge toll吗，正好又支持了后面的结论说，不应该由司机来承担建设的费用，因为他们不会得到什么benefit吗？

但答案却是D

纯属个人意见。

题目问的是下面什么原因能说明 official收费是费力不讨好的事。

那D 很明显，说根据以往经验，收钱之后 ，大家宁可绕道走，也不愿意做火车。
所以，对交通没缓解， 火车没人做，结果开车的人还得天天绕大弯路。
既然这样，那收钱一点好处没有。

C的话
说大伙拼命在便宜的时候多买点token. 但是一旦他们手里的买的token 都用完了，他们怎么办
题里并没说。 如果他们都去坐火车了，那说明，official的目的是可以达到的。所一没有weaken
