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.

老师，这道题根据您的答案，定义应该是1000＝2的9次方乘以X。 但是这样的话这个X就不能是整数了，不符合上面92题的定义呀。 所以没想明白，觉得应该还是1000＝2*2*2*5*5*5。选E

从条件1看，p也可以等于32呀！ 32是2的5次方，所以的质数可以写成1和2，同时为了满足＞1的条件。只是只能是2，所以不能准确推理呀 只有当两个条件合起来，p是33或35时才能满足。因此应该选C不是A

After driving to a riverfront parking lot, Bob plans to run south along the river, turn around, and return to the parking lot, running north along the same path. After running 3.25 miles south, he decides to run for only 50 minutes more. If Bob runs at a constant rate of 8 minutes per mile, how many miles farther south can he run and still be able to return to the parking lot in 50 minutes?
请问这里的50为什么是总的时间呢，不是3.25miles之后的时间吗

张老师你好，这道题目我不太懂C为什么错。因为这道题目我的方法是直接定位到黄色highlight部分，然后看这句话的前后句子，因为前面一句话看着好像比较无关，我就重点看了后面一句话，说了这些guilds的women是有legal和economic的privileges ，所以我一看C就对了。然后正确答案是A，不太懂怎么才能选对，也不理解c为什么是错的，虽然A看了这句话也对，但是考试的时候做这种题目我为了节约时间通常都是只看highlight附近的句子的，求指教！然后这类型的题目大概难度系数是多少？谢谢

Last year a global disturbance of weather patterns disrupted harvests in many of the world’s important agricultural areas. Worldwide production of soybeans, an important source of protein for people and livestock alike, was not adversely affected, however. Indeed, last year’s soybean crop was actually slightly larger than average. Nevertheless, the weather phenomenon is probably responsible for a recent increase in the world price of soybeans.

Which of the following, if true, provides the strongest justification for the attribution of the increase in soybean prices to the weather phenomenon?
老师您好，题目的意思说天气原因影响了很多重要的农作物产量，然而大豆并没有受到很严重的影响。然而最近大豆价格的上涨可能是由于天气导致的，问哪个可以增强因为天气导致的。首先我抓住了问题的重点要围绕天气导致的大豆价格上升，b选项无关，c选项看起来有点跟背景信息抬杠，题目说大豆产量还小幅度上升了，而且c说several years ago是不是时间上的张冠李戴呢？d选项应该是说大豆需求反而下降了，e没有体现weather所以排除吗？剩下a选项我能想得通，但是做题的时候cde都乍一看很干扰啊，有什么办法能抓出这三个选项的致命错误吗，谢谢老师。

思路： 文中结论说由于孩子比大人更容易感染influenza， 新的给孩子打的预防针能可以大力度的减少病菌的传播。 问支持。A说的是就算是一个人接种了both疫苗，也不会产生反应。 因为我觉得聊的是推广这个疫苗会不会预防疾病的事情。那A也就是减少了一个注射疫苗的 出现accident的可能性，堵上了一个范反向结果的洞。很支持啊。 选了A。 E说的是 很多家长更会让孩子接种疫苗，如果疫苗不要求一个injection. 感觉这题上就没有聊这疫苗形势是打的还是怎么的。我当时直接排除了E 。 求老师解答 为啥E比A好。谢谢！
