According to the Tristate TransportationAuthority, ** certain improvements to the main commuter rail line wouldincrease ridership dramatically.
Theauthority plans to finance these improvements over the course of five years byraising automobile tolls on the two highway bridges along the route the railline serves.
Although the proposedimprovements are indeed needed, the authority's plan for securing the necessaryfunds should be rejected because it would unfairly force drivers to absorb theentire cost of something from which they receive no benefit.

Which of the following, if true, would cast themost doubt on the effectiveness of the authority's plan to finance the proposedimprovements by increasing bridge tolls?

(A) Before the authority increases tolls on any ofthe area bridges, it is required by law to hold public hearings at whichobjections to the proposed increase can be raised.

(B) Whenever bridge tolls are increased, theauthority must pay a private contractor to adjust the automated toll-collectingmachines.

(C) Between the time a proposed toll increase is announcedand the time the increase is actually put into effect, many commuters buy moretokens than usual to postpone the effects of the increase.

(D)When tolls were last increased on the two bridges in question, almost 20percent of the regular commuter traffic switched to a slightly longeralternative route that has since been improved.

(E) The chairman of the authority is a member ofthe Tristate Automobile Club that has registered strong opposition to theproposed toll increase.

答案是D，我选的时候再C和D之间犹豫了半天，可还是选错了。我觉得C和D都可以cast the most doubt.

第一题
C) Between the time a proposed toll increase is announcedand the time the increase is actually put into effect
时间是“宣布要实施这个政策，到政策实施之前”这一段，与这个政策实施后的效果无关

第二题
前提：Generally scientists enter their field with thegoal of doing important new research and accept as their colleagues those withsimilar motivation.
结论：Therefore, when anyscientist wins renown as an expounder of science to general audiences, most other scientists conclude thatthis popularizer should no longer be regarded as a true colleague.

D）直接连接前提和结论，正确
C）题目根本没提到什么成为 a famous popularizer 是不是需要completed any important research，无关选项。

逻辑的根本还是，它说什么，你就跟着说什么
