119.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. —>（困难）举行听证会不表示这计划不可行（不表示困难不可克服）

(B) Whenever bridge tolls are increased, the authority must pay a private contractor to adjust the automated toll-collecting machines. —>如果计划成功募集到足够资金，那工程所需支付的钱与之相比简直是九牛一毛，无甚影响

(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. —>可能有些人（通过提前买票）而使计划中原本有的资金减少了些许，但如果计划成功，募集到的资金将远远大于提前买票损失掉的资金，计划将依然有效

(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. —>（注意时态：先例可以证明）如果以前有类似该募钱计划，但遭失败-有20%的常客（注意：这是一个高比例，对于常客而言）不付钱 D

(E) The chairman of the authority is a member of the Tristate Automobile Club that has registered strong opposition to the proposed toll increase. —>别人反对跟计划本身无关（此困难并非不可克服）

这个C项我觉得是削弱了结论么，而OG的解释却是那样，谁会那样想啊！
