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 high-way 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.

我做这道题时，四次有三次选择了A：首先排除了选项B、E，感觉C、D两个选项意思上都能weaken，但是程度不够确定，所以也排除了。

这道题目也是OG10-119，讨论的帖子很多，我看完了还是犯迷糊，而且大家主要是对选项C、D两个拿不准，没有像我一样犯了选择A的错误。

请高手指点！

A有诉诸权威的意味，且看清提干问的是什么，

“effectiveness of the authority’s plan ”

如果选A，可以说和提干所问毫不相干，

Even the plan was denied, the plan is also effectiveness.

Is it true?

i don't think so...

A选项，试问lz，从逻辑上如何削弱“有效性”

无论议案在听证会上被通过还是被否决，都无法提供任何关于对“有效性的”说明

能说通过就是有效，不通过就是无效么？OR vice versa?

The logical structure of authority is

A (Increased car toll) leads to B (raise enough money for railroad);
The assumption is "A is sufficient for B."  (D) attacks this assumption by indicating that "Increase of car toll" (A) may be insufficient (for B) because many perople can use alterative routine as they did before.

"20 percent" in answer D is very confused.

If there was "80 percent", answer D is no question.
