55.   (34557-!-item-!-188;#058&007575)

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.

答案为D

请问选项C错在哪里呢？？ 谢谢

如C自己说的那样 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

看了楼主MM几个贴子，猜测一下

你是不是刚开始准备GMAT？

如果是的话建议先把OG上的解释看几遍

看懂之后你昨天问的大部分问题都可以解决

prep个人觉得是考前热身做更有效

就这个小建议 

猜错了不要拍我

C 的意思是说：通勤者为了避免受涨价的影响，在法令宣布之后和正式实施之前买了很多票（反正不过期，咱就留在家里慢慢用），  this choice still  证明了该计划有效果-----政府还是筹集到了资金

注意审题，题目要求是削弱该计划的实施效果
