A certain mayor has proposed a fee of five dolloars per day on private vechiles entering the city,claiming that the fee will alleviate the city's traffic congestion. The mayor reaons 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 talking a private vechile into the city
B The cost of parking fees already makes it considerably more expensive for most people to take a provate vechile into the city than to take a bus.
答案是B 但为什么不是A呢
答案是这么解释的 what flaws exists in the mayor's reasoning? The mayor apparently believes that saving money is the decisive issue for drivers. If, however,drivers are already paying more in parking fees than they would in fares as bus commuters,then saving money is not the reason they are choosing to drive their cars rather than take the bus. These drivers will not change their behavior simply to save money
A is wrong because you cannot TALK a vehicle into the city. Just kiding.
B is right because it removes the financial cause as the reason to DETER people from driving the private vehicle into the city since these drivers are paying a lot of EXTRA money for parking. They will not give it a damn if they have to pay five more dollars.
