题目：

In the year following an eight-cent increase in the federal tax on a pack of cigarettes, sales of cigarettes fell ten percent.  In contrast, in the year prior to the tax increase, sales had fallen one percent.  The volume of cigarette sales is therefore strongly related to the after-tax price of a pack of cigarettes.
 
The argument above requires which of following assumptions?

选项:

A、During the year following the tax increase, the pretax price of a pack of cigarettes did not increase by as much as it had during the year prior to the tax increase.
B、The one percent fall in cigarette sales in the year prior to tax increase was due to a smaller tax increase.
C、The pretax price of a pack of cigarettes gradually decreased throughout the year before and the year after the tax increase.
D、For the year following the tax increase, the pretax price of a pack of cigarettes was not eight or more cents lower than it had been the previous year.
E、As the after-tax price of a pack of cigarettes rises, the pretax price also rises.

Defying efforts by polio makers on both sides of the Atlantic at restraining it, the United States dollar, continuing its rise, reaching its highest level in six years against the German mark.
老师这道题DE我不会排除，老师说排除E的原因是and后不定式没法跟continuing并列，所以排除，我觉得这个理由太牵强了吧，and后不定式可以跟to restrain并列啊。所以没法通过这个方法直接排除吧？我感觉只能通过语意判断 reach只能是状语形式，不能用并列了，但是这样的区分本身就很微妙，太难太难了。。老师有其他好的方法区分吗？

Organized in 1966 by the Fish and Wildlife Service, the Breeding Bird Survey uses annual roadside counts along established routes for monitoring of population changes of as many as, or of more than 250 bird species, including 180 songbirds.
金栩竹老师，您说第一时间排除AB，是因为counts和routes是复数，但是monitor的动作发出者为什么不能是BBS呢？如果是BBS那用单数形式没问题啊。根据句意好像发出者确实是BBS这个机构吧。所以根据这个单复数AB好像排除不了。

老师，我选了D.因为我认为because of 是修饰前面的accuse 的，表示为什么控告这个银行，而A B的by是修饰engaging 的。请问这怎么区分呢？请老师纠正我思路的错误，谢谢老师
