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.

The milk of many mammals contains cannabinoids, substances that are known to stimulate certain receptors in the brain. To investigate the function of cannabinoids, researchers injected newborn mice with a chemical that is known to block cannabinoides from reaching their receptors in the brain. The injected mice showed far less interest in feeding than normal newborn mice do. Therefore, cannabinoids probably function to stimulate the appetite.

Some species of Arctic birds are threatened by recent sharp increases in the population of snow geese, which breed in the Arctic and are displacing birds of less vigorous species.  Although snow geese are a popular quarry for hunters in the southern regions where they winter, the hunting season ends if and when hunting has reduced the population by five percent, according to official estimates.  Clearly, dropping this restriction would allow the other species to recover.

老师您好！ 我找出来的错误是以下几个 1.30个打折商品的样本太少了 2.4天样本太小，可能只是巧合 3.回答的顾客问的就一定是可靠的回答吗 4.花费超过100美金并不是一个很大的量 5.more than a half 并不意味着数据足够大 我想要解决的问题如下 1.我的出发点是试图找出这个问卷调查法的错误，比如哪个数据不可靠，样本不够有代表性，来证明他们是错的，麻烦老师说一下，我这样找为什么偏离正确答案这么多？ 2.我做错这道题的潜在原因是什么？ 3.看英吉老师的讲解视频中，感觉老师用那个“先找结论，后看完成这个结论需要哪些步骤”的方法，在这题中没有体现，不明白“分步走”在这题中怎么实现，麻烦老师解释一下这题怎么先分步确立各个阶段的目标？
