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.

Not one of the potential investors is expected to make an offer to buy First Interstate Bank until a merger agreement is signed that includes a provision for penalties if the deal were not to be concluded.
看到正确答案之后有一种恍然大悟的感觉，可是不知道当时为什么做错了。 首先看到题目中的not one of the investors我排除了DE，因为应该用单数的动词形式，所以在ABC中选择。 然后我在for...和to do之间犹豫了一下，不确定所以往后看。 C选项后面agreement be signed by them太罗嗦所以排除。 AB之间有好几个不同点，除了之前说到的还有agreement is signed和they sign a merger agreement，及句子后的were和was。 当时做题想的是deal是单数，所以用was，而且我认为签协议比协议被签要直接。其实不是很清楚错在哪里了（were那里之前有考虑过虚拟语气，但是不是很确定）

The primary purpose of the passage is to
在做题时进行了跳读 第一段第一句讲了一个被人们忽略现象，然后后面的两句都是在解释这个现象，所以跳过。 第二段第一句讲了一个什么发现可以解释一个现象，第二句就是对其解释然后跳过，第三句有个However，但是大致看了一下感觉是对细节进行的转折并不影响观点，最后一句就得出一个结论。 再读完后就选了C，排除正确答案A是因为感觉文章没有谈论过这个选项的重要性。 请老师告诉我下我的思维是在哪里出了问题，谢谢~
