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.
E、As the after-tax price of a pack of cigarettes rises, the pretax price also rises.

 The news media is often accused of being willing to do anything for ratings. However, recent action by a television network indicates that the news media is sometimes guided by moral principle. This network had discovered through polling voters on the east coast that the Republican candidate for President had garnered enough votes to ensure victory before the polls closed on the west coast. However, the network withheld this information until the polls on the west coast closed so that the information would not affect the outcome of key congressional races.
Which one of the following most strengthens the argument? 
这个... 我把B排除了.. 因为感觉里面没说他要不要predict所以感觉是无关的.. 我们是怎么想predict和公布公布有关系呢...

When an active tooth in the shark's jaws is lost or worn down, many spare teeth lie in seemingly limitless reserve, each of which are ready to slide into the appropriate position.
错选了B，我读完题觉得语义强调的是在任何时候鲨鱼的牙齿掉了，就有新的补上。排除A是因为 each of which后面是is，排除C、E因为each one of which多余；E我也留下来了，但是觉得语义更想说明这个whenever，于是我想whenever先说会比较好，于是就选了B。

这道题问了一个例子的作用，这个例子，然后根据文章脉络读这个例子支持的论点。 然后我读到了例子前一句说了一个事实，这个例子是since打头，例子后半句说：因此历史学家诧异于一个事实xxxxx。 这个时候我不知道该往上读还是往下读，做题过程中我觉得例子是一个原因，in order to引出后半句“历史学家们诧异xxx”，因此往后读了，没有选对，选了E。 不知道哪里做的不够好，希望老师指出。辛苦了！ 另外：想请问老师，当遇到这种比较难的社科类文章，又出现比较多的不同人物的观点句“A claimed that...”，“B argues that...”，“C insisted that...” 扫读原文把握观点和脉络的时候，该如何正确判断哪些要读，哪些不需要读？ 问题比较多，谢谢老师！
