Feifei-64

有道题想请教大家:

64, 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.

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.

答案选D,但是我觉得A和D表达的意思是一样的,为什么选D不选A? 谢谢!

文中说的"increase in parking violationswill result in a greater number of parking fines collected ''不就是指违规的人或车量增多来增加市政收入的意思吗?

举个例子说明：

提高逻辑成绩能提高GMAT成绩。

结论：提高gmat成绩必须要提高逻辑成绩。这个结论能成立吗？可以通过提高阅读或者语法来提高逻辑成绩吧。
