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 significance of Monet’s work is reflected in a recent discussion of art more than it was in his own descriptions. He is, usually, considered a founding member of French impressionists. Thus, his descriptions are unlikely to do more than confirm what he thought to be true.

Researchers believe that we will ultimately be able to explain all "psychic" phenomena. Achieving this goal requires knowledge of how mental images are "sent" and "received" over distance and how senders and receivers interact at a biological level. At present, there is a substantial amount of fundamental knowledge about receiving images and sending images. Thus, as researchers claim, psychic phenomena will soon be explainable.

Psychologists have studied the impact a person’s attitude has on his ability to accomplish tasks. In one study, a group of college students was outfitted with contraptions designed to administer soothing heat pulses to the students’ neck and shoulder muscles. The students were told that the pulses would enhance their performance of in-class assignments. Only half of these contraptions worked, but neither the students nor the psychologists were told which students would actually receive these pulses. This component of the experiment is often frustrated, however, because

 The news media is often accused of being willing to do anything for ratings. However, recent action by a television network indicates that the news media is sometimes guided by moral principle. This network had discovered through polling voters on the east coast that the Republican candidate for President had garnered enough votes to ensure victory before the polls closed on the west coast. However, the network withheld this information until the polls on the west coast closed so that the information would not affect the outcome of key congressional races.

At present the Hollywood Restaurant has only standard-height tables.  However, many customers come to watch the celebrities who frequent the Hollywood, and they would prefer tall tables with stools because such seating would afford a better view of the celebrities.  Moreover, diners seated on stools typically do not stay as long as diners seated at standard-height tables.  Therefore, if the Hollywood replaced some of its seating with high tables and stools, its profits would increase.
The argument is vulnerable to criticism on the grounds that it gives reason to believe that it is likely that
