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 total market value of real estate in Altonville has steadily declined over the past four years.  This decline has meant that the overall figure on which the city's property tax is based ─ the assessed value of that real estate ─ has also declined.  Moreover, the percentage of assessed value that was paid as property taxes to the city did not change during this period.
 
The information above most strongly supports which of the following?t

Economist: The price of tap water in our region should be raised drastically. Supplies in local freshwater reservoirs have been declining for years because water is being used faster than it can be replenished. Since the price of tap water has been low, few users have bothered to adopt even easy conservation measures.

The two sections in boldface play which of the following roles in the economist’s argument?
老师 我感觉做这种boldface题我经常错 总是分不清哪个是conclusion 逻辑关系能分清 但哪个是conclusion比较一眼难找 这道题我选了A

Agricultural societies cannot exist without staple crops.  Several food plants, such as kola and okra, are known to have been domesticated in western Africa, but they are all supplemental, not staple, foods.  All the recorded staple crops grown in western Africa were introduced from elsewhere, beginning, at some unknown date, with rice and yams.  Therefore, discovering when rice and yams were introduced into western Africa would establish the earliest date at which agricultural societies could have arisen there.
 
Which of the following is an assumption on which the argument depends?
请陆老师回答一下，感谢！这一题中是如何排除B的呢？B说因为没有主食是来源于西部非洲本地的，所以知道rice和jam被引进的时间就可以知道最早的农业社会是什么时候出现在那里的。觉得这个选项也不是重复premise，因为原文说的是Several food plants, such as kola and okra, are known to have been domesticated in western Africa, but they are all supplemental, not staple, foods.，而这里B说的是no plants native to western Africa that, if domesticated, could serve as staple food crops.，意思不完全一样。然后A为什么是assumption呢？感觉不明白这里的逻辑关系。

Ramirez: The film industry claims that pirated DVDs, which are usually cheaper than legitimate DVDs and become available well before a film's official DVD release date, adversely affect its bottom line. But the industry should note what the spread of piracy indicates: consumers want lower prices and faster DVD releases. Lowering prices of DVDs and releasing them sooner would mitigate piracy's negative effect on film industry profits.

The argument above relies on which of the following assumptions?

请陆老师回答一下我的问题，感谢。 第一，这一题中的B选项是不是confirm了premise：But the industry should note what the spread of piracy indicates: consumers want lower prices and faster DVD releases. 但是我总觉得就是重复了这句话，如果是重复premise的话就是错误了。所以想请问confirm premise和重复premise区别在哪里，如何界定。 第二，请问一下D选项为什么不可以选。D感觉属于新信息。一些盗版DVD卖家可能会终止生意，这样的话不也就使得revenue上升，也就mitigate piracy's negative effect on film industry profits.
