Accordingto the Tristate Transportation Authority, making certain improvements to themain commuter rail line would increase ridership dramatically.  The authority plans to finance theseimprovements over the course of five years by raising automobile tolls on thetwo highway bridges along the route the rail line serves.  Although the proposed improvements are indeedneeded, the authority's plan for securing the necessary funds should berejected because it would unfairly force drivers to absorb the entire cost ofsomething from which they receive no benefit.


Whichof the following, if true, would cast the most doubt on the effectiveness ofthe authority's plan to finance the proposed improvements by increasing bridgetolls?

(A)Before the authority increases tolls on any of the area bridges, it is requiredby law to hold public hearings at which objections to the proposed increase canbe raised.
(B)Whenever bridge tolls are increased, the authority must pay a privatecontractor to adjust the automated toll-collecting machines.
(C)Between the time a proposed toll increase is announced and the time theincrease is actually put into effect, many commuters buy more tokens than usualto 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 of the Tristate Automobile Club thathas registered strong opposition to the proposed toll increase.
正选为D，C项为什么不对呢？

自己先猜一下，是因为C项的做法不可能使passengers撑过five years吗？

C 人们买TOKENS 使TOLLS的效果延迟，但延迟并不是没效果；
D 20%的人选择改变路线了（更直接~）

DO U THINK SO~?
