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.

这道题目题库没有，想请老师帮忙解答下。答案是300,000 A real estate agent sold five houses during the past month. The median sales price of these houses was $150,000 and the average (arithmetic mean) sales price was $200,000. The sales price of the most expensive house was at least three times the sales price of the least expensive house. Based on the information provided, what is the minimum possible sales price for the most expensive house? 想了很久，如果是求最大的数的最小值，那么其他的数就要取最大，如果把房子设为：x1 x2 x3 x4 x5 x6 x7,则x4=150,000.要使得其他的数最大，那么x1,x2,x3就要取到150000，x5,x6这个时候应该怎么想呢？ 还有那个题目中最大的数与最小的数有个限定条件我不会用。

The primary purpose of the passage is to
我想请教慧雯老师 阅读基础课的第5篇文章(The fossil remains of the first flying ...那篇)， 问题很细，但是我觉得不弄清的话会对实战产生毁灭性打击： 我在读第一段的时候，直接跳读了- reptiles or birds - 这三个词，因为一般这种插入语一般不都是对前面的话进行解释，可以不读吗， 所以我把第一段的大意概括成了：1、P如何飞的 2、 P是什么 之后看了您讲解的视频，我才意识到“-reptiles or birds -” 对后面的提示作用太重要了，没读这部分对后面第四段的主旨提取是会比较confuse的。我第二段第三段提取主旨的都是正确的，但到第四段，我提取的主旨为：P是热血动物。压根没想到热血动物和鸟能挂上钩，如果第一段读了"-reptiles or birds-", 我再读第四段肯定是能反应过来的。 所以这种双破折号里的东西读不读呢，需要分情况讨论吗？（如果您想说前面句子没读懂，后面双破折号里的内容就应该读的话，那我其实是理解了"what these creatures were"这句话才没读的） 另外，我在读第五段 第一句时，我看到第一个状语by 直接快速扫过了，导致没有注意这三个并列的by , 导致我把each hypothesis has its difficulties直接理解成了第二 三 四段的理论都有其缺陷，但是读到后面内容的时候又发现不是说二 三 四段的，所以就蒙了。 那以后碰到这种状语by 需要读吗，要分情况讨论吗？
