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.

(C) Most of the people currently riding the bus do not own private vehicles.

(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.

Certainly for B. Please pay attention to the word ALREADY. Key B means that it is a currently existing condition that the private vehicle drivers spend more than the people taking bus. The mayor's reasoning is that if the private vehicle drivers spend more than the bus takers, then the private vehicle drivers will swith from using their cars to using the bus. Hoever, If currently the spending of the car drivers is already higher than the bus takers, then it will not make any sense to adopt the plan referred in the reasoning (Five dallars is absolutely not an amount huge enough to change the driver's attitude because we can see  the phrase"considerably more expensive"), because the currently existing condition has no good bearing on the congestion.

B给出了一个context, 就是说现在的的停车费已经很贵了。 可是既然如此还是交通拥挤，就证明交通拥挤和花的钱多不多没有关系，一定另有原因。而市长提出的proposal同样是增加费用，所以是无效的，weaken了文中结论
