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.

What is the value of (x - y )4?
(1)       The product of x and y is 7.
(2)       x and y are integers.
看了答案的解释说，当条件1，2连力的时候，X，Y的值是确定的，1,7。所以选C。 但我觉得符合条件1,2连力的，还有-1和-7。如果这两种情况都成立的话，这时候就有2中可能性了。也就不是有唯一答案了。

Because it was long thought that few people would watch lengthy televised political messages, most televised political advertisements, like commercial advertisements, took the form of short messages.  Last year, however, one candidate produced a half-hour-long advertisement.  During the half hour the advertisement was aired, a substantial portion of the viewing public tuned into the advertisement.  Clearly, then, many more people are interested in watching lengthy televised political messages than was previously thought.
 
Which of the following is an assumption on which the argument depends?
错选了D。觉得D谈论的是喜欢政治话题的人看电视的事，觉得和原文沾边，就选了D。看过答案后，觉得E转换频道这件事也和原文沾。但是怎么比较才能选对呢？

In Gandania, where the government has a monopoly on tobacco sales, the incidence of smoking-related health problems has risen steadily for the last twenty years.  The health secretary recently proposed a series of laws aimed at curtailing tobacco use in Gandania.  Profits from tobacco sales, however, account for ten percent of Gandania's annual revenues.  Therefore, Gandania cannot afford to institute the proposed laws.

In the past, most children who went sledding in the winter snow in Verland used wooden sleds with runners and steering bars. Ten years ago, smooth plastic sleds became popular; they go faster than wooden sleds but are harder to steer and slow. The concern that plastic sleds are more dangerous is clearly borne out by the fact that the number of children injured while sledding was much higher last winter than it was 10 years ago.

Which of the following, if true in Verland, most seriously undermines the force of the evidence cited?
这道题上课讲过，但是记不清楚了。 C 是怎么驳斥原文的？ 是说 使用的条件更广泛会降低对 plastic sledge 滑板危险 的相信度？

For similar cars and drivers, automobile insurance for collision damage has always cost more in Greatport than in Fairmont.  Police studies, however, show that cars owned by Greatport residents are, on average, slightly less likely to be involved in a collision than cars in Fairmont.  Clearly, therefore, insurance companies are making a greater profit on collision-damage insurance in Greatport than in Fairmont.
 
Which of the following is an assumption on which the argument depends?

这道题有N 多人问， 但是并没有解答下面这位提问者的疑问，我也有同样的疑问。 我如果多读一句，就能做出正确答案。 可是我不知道从哪里找暗示让我去多读这一句， 请您指点 这题我定位到Paczynski reasoned that if MACHO's make up this halo, a MACHO would occasionally drift in front of a star in the Large Magellanic Cloud, a bright galaxy near the Milky Way. 且只读了这句，因为原文问的是MACHO怎样了，这句回答了，但是这样读后只有A沾边啊，B排除是因为我读成了影响star，上句话没有看出影响。 review时发现B其实是后面一句，想问：如何判断定位后读多少（读少了经常会直接排除正确选项，有时候读得多了又干扰排除)

In 1992 outlaw fishing boats began illegally harvesting lobsters from the territorial waters of the country of Belukia.  Soon after, the annual tonnage of lobster legally harvested in Belukian waters began declining; in 1996, despite there being no reduction in the level of legal lobster fishing activity, the local catch was 9,000 tons below pre-1992 levels.  It is therefore highly likely that the outlaw fishing boats harvested about 9,000 tons of lobster illegally that year.
 
Which of the following is an assumption on which the argument depends?
读选项后就排除了C/D/E B选项说的是自从1992年开始每条船非法捕龙虾的在稳定增加，觉得和原文沾边就留下了...而A选项觉得不是很明白最后就还是选择了B觉得与文章关系更直接...听了之前答疑的录音也还是不明白，是因为什么原因最终把B排除的...希望管老师指点
