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.

Unlike human runners, who broke the four-minute mile in 1954 and they consistently recorded faster times ever since, horses in classic races such as the Kentucky Derby have had winning times with little improvement:  Secretariat's world-record-breaking Derby tine of 1:59 2/5, for example, was set in 1973 and remained unsurpassed more than a quarter of a century later.

The spacing of the four holes on a fragment of a bone flute excavated at a Neanderthal campsite is just what is required to play the third through sixth notes of the diatonic scale—the seven-note musical scale used in much of Western music since the Renaissance. Musicologists therefore hypothesize that the diatonic musical scale was developed and used thousands of years before it was adopted by Western musicians.

Which of the following, if true, most strongly supports the hypothesis?

In the late 1980’s, the population of sea otters in the North Pacific Ocean began to decline. Of the two plausible explanations for the decline—increased predation by killer whales or disease—disease is the more likely. After all, a concurrent sharp decline in the populations of seals and sea lions was almost certainly caused by a pollution-related disease, which could have spread to sea otters, whereas the population of killer whales did not change noticeably.

Which of the following, if true, most seriously weakens the reasoning?

原文说北太平洋水獭的数量在下降，两个解释，一个是被鲨鱼吃了，一个是生病死了，生病更可能，因为另外两个海洋生物生病能传染给水獭，鲨鱼的数量每怎么变。 我选的D，选项目和原文都围绕着水獭的数量的下降这个事情谈的，后面的urchin看似无关，实际上和水獭联系上了。老师不是说可以演绎吗？这个选项把u列为水獭下降的原因有老师说的打开其他出口来驳斥的感觉啊。我怎么觉得A无关呢？A是如何驳斥的？

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.
 
Which of the following, if true, most seriously undermines the argument?
