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.

Normally, the pineal gland governs a person’s sleep-wake cycle by secreting melatonin in response to the daily cycle of light and darkness as detected by the eye. Nonetheless, many people who are totally blind due to lesions in the visual cortex of the brain easily maintain a 24-hour sleep-wake cycle. So the neural pathway by which the pineal gland receives information from the eye probably does not pass through the visual cortex.

For purposes of evaluating the argument it would be most useful to establish which of the following?
想问英吉老师一个问题，希望他可以作答。我对本题理解是，d和e，一个说不能维持24小时周期的人，一个说看得见的人，但原文围绕的是能维持24小时周期瞎子说的，所以d和e可以杀掉。但是我觉得这么做不太对，因为英老师课上说，一种支持方法是说它的一个对立面不好，进而反向加强了它的推论。选项说到了瞎子的对立面，就是看得见的人，是不是也不一定错呢？超出原文范围和说它的对立面，我总是容易混淆，请老师帮忙

Shoppers in sporting goods stores, unlike in department stores, do very little impulse shopping, not buying a pair of skis and a boomerang when they come in for a basketball, but they leave with a basketball only.
选了C。听了录音说正确选项分号后内容是在解释impulse shopping，不应该是C选项中的并列关系。做的时候没有意识到C选项的并列，只是看没有错误且语意通顺可能让人理解，D选项末尾as well用在否定句没有见过，感觉not和as well有些矛盾，就像一句话中and和instead连用，求稳就选了C。求问老师遇到这种情况该怎么思考？

Neither a rising standard of living nor balanced trade, by itself, establishes a country's ability to compete in the international marketplace.  Both are required simultaneously since standards of living can rise because of growing trade deficits and trade can be balanced by means of a decline in a country's standard of living.
If the facts stated in the passage above are true, a proper test of a country's ability to be competitive is its ability to

老师，这道题abe比较对象不对所以被排除，我想问的是，如果想要表达sporting goods store和department store的比较，这个句子应该怎么写呢？是不是“in sporting goods stores,unlike (in)department stores, shoppers......”这样，把介词短语提前，in可以有也可以省略，这样对吗？
