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

Acertain mayor has proposed a fee of five dollars per day on private vehiclesentering the city, claiming that the fee will alleviate the city's trafficcongestion.  The mayor reasons that,since the fee will exceed the cost of round-trip bus fare from many nearbypoints, many people will switch from using their cars to using the bus.

Whichof the following statements, if true, provides the best evidence that themayor's reasoning is flawed?

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

(B)The cost of parking fees already makes it considerably more expensive for mostpeople 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 ratherendure traffic congestion than pay a five-dollar-per day fee.

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

这题答案是B，我知道。

但是想请问一下，A到底是无关，还是加强？

我最开始理解的是，A讲汽油费贵，所以导致汽车花费比bus高，人们会从汽车换bus。后来又会想，A里面完全没有提到多收5磅，也没有提到换成bus，也有可能是无关。所以晕了，想问一下，这个A选项到底有关无关？

无关，题目没有提到汽油价格。本题逻辑关系和汽油价格无任何联系。
关于你得解释我只能说你想多了，A引出了一个新的概念（汽油价格）。在有更好更直接的选择的情况下优先去除新的概念选项。
