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.

Which of the following most accurately summarizes the relationship between Arizona v. California in lines 38–42, and the criteria citing the Winters doctrine in lines 10–20?
原文见附件。思路：没有被原题干的10-20所骗到，初读文章后，知道这是个细节，38-42读不出 这两者的关系。不知道如何定位。 对该类题材的文章比较头疼，即使精读完整篇文章之后也只能知道个大概的框架，但是 句子间的逻辑关系（也就是英老师讲的阅读的第三点）拿不下来。怎么办？ 对于此类文章，以后需要怎么练习才可以拿下阅读的第三点（细节与前后句之间的逻辑关系）。感谢！

Proposed new safety rules for the Beach City airport would lengthen considerably the minimum time between takeoffs from the airport. In consequence, the airport would be able to accommodate 10 percent fewer flights than currently use the airport daily. The city’s operating budget depends heavily on taxes generated by tourist spending, and most of the tourists come by plane. Therefore, the proposed new safety rules, if adopted, will reduce the revenue available for the operating budget.

The argument depends on assuming which of the following?
假设题，选项正确的前提条件要与原文沾边，锁定C和E。 C：一旦新的安全条例采纳，游客人数会减少，减少的人数 主要不是来自于那些来B城市不消费的游客。那么减少的人数 只能从来B城市消费的游客里面降了，根据原文B城市运营 预算依赖于游客的消费，所以C满足原文结论。 E：采纳新的安全条例，每次航班的地乘客不会增加。 当时没有选择E的思路：1，没有直接的消费关系； 2，乘客和游客还是有区别的 但是答案选择E，不太理解。望解答，谢谢~
