59.
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.
我选C。
这道题逻辑链：因为私家车进城费上涨使得很多人乘公交车，所以城市交通堵塞会得到舒缓。
我觉得C削弱了论点。因为现在乘公交的大多数人都没有私家车，所以私家车进城费上涨政策影响不到他们，也就是说，这个政策不会使交通得到舒缓。
B我觉得也没有错，但是C肿么就错了呢。。。很多人都没考虑C，把它当做无关选项。。是不是我思路有问题啊。。
