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 roundtrip 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.

答案选B 但是根据lawyer flaw in the reasoning 里面说 每个元素都需要在原文出现过。B选项中the parking lot fee 明显是个新元素。按我对lawyer的解题方法的理解，B是不对的。 我不知道我哪里对lawyer的解题方法理解错了？
九．FLAW IN THE REASONING

看原文：找出原文错误
找答案：描述原文错误的为答案。描述的因素原文没有的为错误答案

TEST：描述原文的推理错误，每个元素都必须在原文出现过。

Well, Lawyer is wrong in this.

For Flaw type question, as in many other questions, the key is to find the assumption of the argument. If any answer choice can attack the assumption made in the argument, that choice is the correct one for the Flaw.

For this question, the assumption is:
Cost is the ONLY consideration for people to choose between transportation means.

B) simply demonstrates that COST is not the only factor. End of the story.

Thanks, Sdcar.

The modifier: MANY.

Many = Some, could be 1, could be 100. If it is one out of 100, who cares his objection!

d哪里不对啊，求解，THX!

原来推理链如此：（1）增加进城费——（2）减少汽车使用——（3）舒缓交通问题
不是lawyer的问题，而是这道题的问题，这道题问的是reasoning law，应该用logic来驳斥，如因果倒置，充分必要混淆等等；但是B答案的驳斥却用fact“事实”来驳斥；
使得这道题更像一道weaken题；weaken的方法是因果割断，有（2）无（3），汽车使用量已经减少，但是交通问题依然存在。

而D的答案many是一个问题，更关键的是GMAT考试需要的是准确以及客观；这种主观判断以及should这种选项大部分情况下不为正确答案。
