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.

1、这道题我想请问老师我的做题思路是否正确？首先上来看原句，前面比较对象一致是动物和家禽比，但是后面来了they，无指代对象，杀掉A；看到B感觉有点奇怪先留着；C选项是拿动物和脂肪对比，杀；D选项是拿脂肪和动物比，杀；E选项比较对象没有问题都是脂肪和脂肪比，只是后面they犯了和A一样的错误，杀。 2、在找对比对象时，是不是一定要找对比的核心词？比如e选项中total fat is less in wild animals中total fat就是要对比的核心，可以这么考虑吗？

ID：1380 各老师给讲解的答案不统一，请问到底D/E哪个选项正确。 1、选D的老师认为，As的后面是主语Those进行了省略，但有歧义的地方是好想比较的主语不完全一致，一个比较的主语是收8000美金的那些机构，另一个比较的主语是收16000美金的那些机构，修饰成分不一致的主语是否可以进行省略？ 2、选E项的主语没有省略，但全民对比项用的结构是 "Institution charge fees of...",后面用的结构是"those charging over..." ,前后结构不一致, 请老师分析一下结构？charge （V）VS charging（Ving）
