标题: 再问prep1 -59

59.(34753-!-item-!-188;#058&007583)

A certain mayor has proposed a fee of five dollars per day on private vehicles entering the city, claiming that the fee will alleviate the city's traffic congestion.The mayor reasons that, since the fee will exceed the cost of round-trip bus fare from many nearby points, many people will switch from using their cars to using the bus.

Which of the following statements, if true, provides the best evidence that the mayor's reasoning is flawed?

(A) Projected increases in the price of gasoline will increase the cost of taking a private vehicle into the city.

(B) The cost of parking fees already makes it considerably more expensive for most people to take a private vehicle into the city than to take a bus.

(D) Many commuters opposing the mayor's plan have indicated that they would rather endure traffic congestion than pay a five-dollar-per day fee.

(E) During the average workday, private vehicles owned and operated by people living within the city account for twenty percent of the city's traffic congestion.

选B，为什么呢~B说对那些开车的人来说停车费很贵。题目说因为fee高了，所以开车的人会去做公交车。
B选项不是加强了原文吗。。。

B说由于停车费的昂贵，有很多人早就已经改乘公交车了，那么市长就没有必要在propose 一个新的方案了，削弱了结论

或者可以这样理解： B说停车费已经很高了，可是交通状况仍然没有改善。那么，如果再采用mayor的新方案，也不会有什么效果。
