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?

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.

The human nervous system and a telephone system superficially resemble each other, not only because the former carries information in the form of electrical impulses and because all of its neural pathways converge in the brain and spinal cord, which together form a kind of central exchange.
请金栩竹老师解答 金老师好，这题关于B有个疑问： 1）both 位置不对，carry .... vs because all of its .....前后不平行，both 应该在 because 前面，像C那样？ 2）您在基础课上说，they 和后面的 its neural 在单复数上不一致。我想问，在平行结构里，前后的单复数也一定要平行吗？还是说在这里，是从句意上理解，要求前后都指 human nervous system ? 3)跳出本题，they 能否指代 the human nervous system 和 a telephone system这个整体 ，这算是复数吗？

Jennifer: Video rental outlets in Centerville together handled 10,000 fewer video rentals in 1994 than in 1993. The decline in rentals was probably due almost entirely to the February 1994 opening of Videorama, the first and only video rental outlet in the area that, in addition to renting videos, also sold them cheaply.

Brad: There must be another explanation: as you yourself said, the decline was on the order of 10,000 rentals. Yet Videorama sold only 4,000 videos in 1994.

Which of the following, if true, would most seriously weaken the force of the objection that Brad presents to Jennifer's explanation?

Often visible as smog, ozone is formed in the atmosphere from hydrocarbons and nitrogen oxides, two major pollutants emitted by automobiles, react with sunlight.
请语法金栩竹老师回答。 看了您的语法基础课，DE两个选项（尤其是D），formed为何不能看作是谓语动词（过去式），由ozone发出？ 我知道 formed in ……作插入语修饰zone，导致缺少谓语V（这种用逗号隔开的，里面都是过去分词，不会出现过去式么？），但这类题我总是习惯把过去分词当成过去式来理解，请老师指教方法。

王文静老师，我这道题目不知道要不要用你上课教的补充完整的方法，than是可以补的，但是exceed我就不清楚了，我说一下我的思路 a.rates 不能和other immigrant group去比 b.如果直接看的话，rates 不能和immigrant group 比。但是我如果补足的话，mideast immigrants are exhiting rates of entrepreneurship exceeding virtually every other immigrant group (do) in the...就是主语比较 c.直接看的话rates 对those是对的，但是!上课主谓宾比较第一道例题题目的c选项是错误的，它是这样的:wild animals have less total fat than that of livestock fes on grain and have more fat of a kind thought to be good for cardiac health,错误原因是than后面补全的话就是wild animals have that of livestock逻辑错误。这道题目c选项补全immigrants from the mideast exhibit rates of entrepreneurship exceeding (immigrants from the mideast exhibiting ) those of virtually every other immigrant group in the increasingly diverse united states economy..不是不对吗，我觉得这两道题的c好像啊 D.同B的错误 E.谓语动词单复数错误 请老师帮忙解答一下，谢谢！到底要不要补全，还是直接简单看看就好，到底c为啥在这道题目对，以前的例题又错
