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.

The passage indicates that Robertson's research in Kenya caused her to change her mind regarding which of the following?
麻烦老师能帮我看看我的思路哪里错了吗？ 做前一全文主旨题时，我浏览了一遍文章，知道这篇文章第一段说R有个理论，就是殖民前，age比gender更重要。但是第二段R又有了研究，大概是说虽然age还是最重要，但是K和G两个地方也不同，gender 在K比在G重要点。 然后看这道题时，问题是问R在K这个地方的研究让她改变了关于啥的理论。所以应该在第二段找，而且在找之前我还看了一下选项想排除找的范围，因为觉得应该都是讨论殖民前的，所以直接把带殖民后的选项都杀了。剩下AB，然后还没找原文，发现A是说R之前的理论，所以跟问题无关，选了B。 请老师解答。

Situation:  For five years the Souper restaurant chain has maintained rapid sales growth in Danport, primarily by opening new restaurants that draw patrons away from other restaurants in their vicinity.
 
Goal:  Souper wishes to achieve continued rapid sales growth in Danport over the next two years.
 
Proposal for consideration:  Continue to open new restaurants in Danport during the next two years at the same rate as in the last two years.
 
In light of the situation, which of the following, if true, most strongly argues that adopting the proposal would be an ineffective way of achieving the goal?
掐时间做时，觉得B和D都对，比较不出来哪个更好，最后选了B，因为觉得B和situation里描述的draw patrons away from other restaurant 有关系。 后来Review的时候觉得： 是不是因为B选项是建立在原文Situation上的，而situation说的是前五年的事，不能代表将来，所以B不对呢？ 谢谢老师～

Radio stations with radio data system (RDS) technology broadcast special program information that only radios with an RDS feature can receive.  Between 1994 and 1996, the number of RDS radio stations in Verdland increased from 250 to 600.  However, since the number of RDS-equipped radios in Verdland was about the same in 1996 as in 1994, the number of Verdlanders receiving the special program information probably did not increase significantly.
Which of the following is an assumption on which the argument depends?
这道题看完之后BCE很快排除，留下了A和D。A说 基本上RDS现在能覆盖的区域以前也能覆盖到。 读完之后没有太大感觉，就先留着了。D说 1996年没安装设备，接收不到信息的人，自从94年就一直就接收不到信息。 原文结论说接受信息的人数没有增加，觉得D好像近点就选了D。 老师，是不是我判断远近的方式不正确，才导致选错的呢？希望老师指导，谢谢。
