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.

B为正确答案，我也认同，讲了另一种方法就可以解决congestion。但是E也有道理啊。congestion的相当一部分是由于住在城里的人造成的。因此对进城vehicle收费不能有效缓解congestion
求讨论

LZ~我觉得B是说私车本来就比公交贵很多，所以收不收那5块钱是不会对人们的选择产生影响的，该开车还是开车~
E是无关选项~题目的关注点是收钱究竟会不会有效果，而且即使这20%住城里的这个措施对他们无效，但还有80%导致congestion的原因呢~你不能保证这个措施对这80%无效~
