PREP1-Q59~求NN指教~

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.


答案：B。问题问是是下列哪项反对了mayor的reasoning，又不是support。B明显是在support嘛，停车费贵得使得人们都开不了车，还不如坐公交呢~而原文不是mayor希望大家多坐公交，少开车嘛~为什么不是D呢？
百思不得其解，望各位NN的指教~

Yeah, I got it, Sanlingjie! Thx so much for your detailed explanation!
The key thing to do is to weaken the reasoning, not the plan itself，right？

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.

According to your explanation, B says the parking  fees are already very expensive. So people will gradually tend to choose to take buses to work. Therefore, B is acting as a supporter to what the mayor says.

D if they endure the congection means that they would pay the 5 dollars for entrance accprding to the question.
