If the city council institutes new parking regulations, city revenues will surely increase, since studies have conclusively shown that, if such parking regulations are put into effect, there is an increase in parking violations, and an increase in parking violations will result in a greater number of parking fines collected.
64. If the statements in the passage are true, which one of the following must also be true?
A. Unless there is an increase in the number of parking violations in the city, city revenues will not increase.
B. If the city council institutes new parking regulations, the council will fall from favor with the citizens.
C. The city council will institute new parking regulations only if an increase in city revenues can be expected to result.
D. If the city council’s new regulations cause more parking violators to be ticketed, the city revenues will increase.
E. Unless the city institutes a complex system of parking regulations, the city cannot expect traffic violations to increase.
原版分析:
Choice C just repeats the conclusion: institution of new regulations -> increase of city revenues. it fails to fill the gap between institution of regulations and increase of revenues.
new regulations -> more violations-> more fines collected(increase of revenues)
D is correct.
我得分析:
题目实际上是个演绎推理,从文中只能推断C是对的,因为C基本就是重复了文中的结论。D只是一个必要条件,提供某种支持而已,怎么可能断定就是通过多开Ticket就赚钱了,也许新制定的法规是押送违章者去强迫为政府劳动打工呢!
至少从题目的问法来看,C是完全没有问题的,即便它只是把文中的结论重复一遍,但是logically absolutely correct!
