紫皮CR 39 想不透！

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.

请教A为何不能成为一个FLAW？

因为油价的高涨所以大家非因为市长的FEE $5而改乘公车？

还是我的逻辑在这有误，油价的高涨是WEAKEN而非FLAW？

FLAW要的是描述原文错误的答案？

 the question is very well explicit stated that is provides the best evidence that the mayor’s reasoning is flawed?

the reasoning involves in fees nothing more.

找FLAW 先承认结论错， 然后再选  A是事实描述  不痛不痒  B的inference说人们有钱 冈冈地   再挨5刀没感觉 不会少开车

D many commuters opposing the mayor's plan have indicated that they would rather endure traffic congestion than pay a five-dollar-a-day fee.怎么解释呢？

还有答案选B，指停车费已经很高了，then，市长再征收5￥一天，是不是更利于阻止cars的使用呢？

答案B 停车费已经很高了,嫌贵不开车的人早就改乘公交了，再多征收每天5￥根本无济于事。所以正好weaken mayor's plan.
