求助 prep cr 55 与前人的逻辑有些不同

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.

正确答案D   可以理解

但是我看到前人的讨论帖说这个结论是这样得出来的：
原文的逻辑是making certain improvements to the main commuter rail line would increase ridership dramatically。然后finance these improvements over the course of five years by raising automobile tolls on the two highway bridges .也就是借增加的人数提高finance.

我觉得好像说反了啊，应该是finance improvements然后就可以进行improvements然后就可以increase ridership。因为原文中说的是improvements would.....那就说明通过的人数的增加应该是improvements的结果啊。

另外我想请问一下，如果这题不是问plan的effectiveness,只是问这个plan（which would cast most doubt on the authority's plan）的话,可以选A么？

多谢大家啦~

in my opinion, the logical chain is:  The authority plans to raise automobile tolls on the two highway bridges along the route the rail line serves, and the acquired funds will be used to  finance the improvements of the main commuter rail line in order to increase ridership dramatically.
