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.

陆旭老师您好，请问这个A选项，第一，they应该是指代不清，不过是否可以指代studies？可以看做“一些研究认为”吗？（think主语必须是人或者动物吗？）第二，A这个选项有些同学和我说livestock是集合名词必须用单数动词 所以应该改为 。。。。than does livestock。。。老师您同意这种说法吗？我查了几本词典，这词好像可以是看成集合名词（类似crew，后面用单数动词）也可以是复数名词（类似cattle，后面用复数动词），还有的说是不可数名词。GMAT或者美国人通常如何看这个词？livestock后面动词应该是单数还是复数？

请张慧雯老师回答一下这篇阅读的两题。 第一题，我定位到第二段（因为整个就是the first explanation”）。但是后面看到选项BCD好像还要定位到第四段“in 1840, about… was rough the same”这两个地方。但是我不知道精准定位是在哪里。然后还是不太懂这篇文章的意思，以及这一题为什么选C。 第二题，看到题干就觉得好难定位，通篇好像都要读，没办法快速根据题干来定位，结果还错选了A。请老师解答一下这一题的突破点以及为啥选D。

请王文静老师回答一下。请问一下这一题为什么选B。我选了E是因为前面说科学家猜测黄蜂被这种气味所吸引，但是后面说in this study，只有grassy odors释放出来了，说明这种气味肯定与grassy odors这种气味不一样。而B说这种气味没有grassy scent，但是原文又说科学家猜测黄蜂是被an odor，reminiscent of cut grass，that is released as the catepillar feeds，意思不就是这种气味类似于cut grass吗？那为什么还会选B。

请陆旭老师回答一下。图片中的这一题为什么不可以选C，我的理解是这个研究是30年前做的，所以不适用于当今的情况，不具备说服力。
