According to the Tristate Transportation Authority, making certain improvements to the main commuter rail line would increase ridership dramatically. The authorityplans to finance these improvements over the course of five years by raisingautomobile tolls on the two highway bridgesalong the route the rail line serves. Althoughthe proposed improvements are indeedneeded, the authority's plan for securing the necessaryfunds should be rejected because it would unfairly force drivers to absorb the entire cost of something from whichthey receive no benefit.
Which of the following, if true, would cast the most doubt on the effectiveness of the authority's planto 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 authoritymust pay a privatecontractor to adjust the automated toll- collecting machines.
C. Betweenthe time a proposed toll increase is announcedand the time the increase is actually put into effect, many commuters buy more tokens than usual to postponethe effects of the increase.
D. When tolls were last increased on the two bridgesin question, almost 20percent of the regular commuter switched to a slightly longeralternative route that hassince been improved.
E. The chairman of the authorityis a member of the TristateAutomobile Club that has registered strong opposition to the proposedtoll increase.
OA是D，看到很多网站的解释，D：当上一次增加过桥费时，大约20%的通勤车转向另外一条稍远的路(不选择这条路)。我的选择是B：增加收费会增加一笔费用用于收费机的调试。 我对于D的考虑是：D说的是上一次收费有20%的车转向其他路了，那么这次还会转么？Gmat里对这种时间先后的类比是不是认为是有效且合理的？ 请NN指教，谢谢。
