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.

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.

Neuroscientist: Memory evolved to help animals react appropriately to situations they encounter by drawing on the past experience of similar situations. But this does not require that animals perfectly recall every detail of all their experiences. Instead, to function well, memory should generalize from past experiences that are similar to the current one.

The neuroscientist’s statements, if true, most strongly support which of the following conclusions?
想请王文静老师解答一下这道题： Book publishing executive: I am becoming increasingly convinced that the interaction between book sales and literary quality is not a simple one. For example, I now believe that no number one best seller will win the major literary prizes. But I also believe that all major literary prize winners will have unusually high long-term sales. If the beliefs that the book publishing executive claims to hold are true, which of the following must also be true on the basis of them? (A) No books with unusually high long-term sales are number one best sellers. (B) At least some number one best sellers are not books with unusually high long-term sales. (C) All books with unusually high long-term sales are number one best sellers. (D) At least some books with unusually high long-term sales are not number one best sellers. (E) No number one best sellers have unusually high long-term sales. 这道题我在限时做的时候可能并不是十分清晰的思考了每一个选项，但是选了正确选项D，但是后来再去细看的时候感觉凭“没有一本头号畅销书可以获奖”和“获奖的书会有异常高的长期销量”这两点，所有的选项我都推不出来，只能是按自己的想法感觉B、D好像还可以，其中D更合适一些。 请问老师这道题正确做的话该怎么去排除选项、推出正确选项呢？谢谢老师！
