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.

Offshore oil-drilling operations entail an unavoidable risk of an oil spill, but importing oil on tankers presently entails an even greater such risk per barrel of oil.  Therefore, if we are to reduce the risk of an oil spill without curtailing our use of oil, we must invest more in offshore operations and import less oil on tankers.
Which of the following, if true, most seriously weakens the argument above?
题目的最后一句话给出结论：在Offshore多投钱，tanker少进口油。问削弱？我选了D，认为指出在offshore那么做的缺点。答案A我反而觉得无关。设计那个tanker感觉文章也没有讨论过这个点。求解。谢谢

Lyme disease is caused by a bacterium transmitted to humans by deer ticks.  Generally deer ticks pick up the bacterium while in the larval stage from feeding on infected white-footed mice.  However, certain other species on which the larvae feed do not harbor the bacterium.  Therefore, if the population of these other species were increased, the number of ticks acquiring the bacterium―and hence the number of people contracting Lyme disease—would likely decline.
 
Which of the following, if true, most strengthens the argument?癮
这三道题目答案中都有only，有起加强作用也有起削弱作用的，麻烦老师分析下only这个绝对性比较强的词在CR中应该如何看待。 第一题：Codex Berinensis, a Florentine copy of an ancient Roman medical treatise, is undated but contains clues to when it was produced. Its first 80 pages are by a single copyist, but the remaining 20 pages are by three different copyists, which indicates some significant disruption. Since a letter in handwriting identified as that of the fourth copyist mentions a plague that killed many people in Florence in 1148, Codex Berinensis was probably produced in that year. Which of the following, if true, most strongly supports the hypothesis that Codex Berinensis was produced in 1148? (A) Other than Codex Berinensis, there are no known samples of the handwriting of the first three copyists. (B) According to the account by the fourth copyist, the plague went on for 10 months. (C) A scribe would be able to copy a page of text the size and style of Codex Berinensis in a day. (D) There was only one outbreak of plague in Florence in the 1100s. (E) The number of pages of Codex Berinensis produced by a single scribe becomes smaller with each successive change of copyist. 第二题：The spacing of the four holes on a fragment of a bone fl ute 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? (A) Bone fl utes were probably the only musical instrument made by Neanderthals. (B) No musical instrument that is known to have used a diatonic scale is of an earlier date than the fl ute found at the Neanderthal campsite. (C) The fl ute was made from a cave-bear bone and the campsite at which the fl ute fragment was excavated was in a cave that also contained skeletal remains of cave bears. (D) Flutes are the simplest wind instrument that can be constructed to allow playing a diatonic scale. (E) The cave-bear leg bone used to make the Neanderthal fl ute would have been long enough to make a fl ute capable of playing a complete diatonic scale.

Retail sales rose 8/10 of 1 percent in August, intensifying expectations that personal spending in the July-September quarter more than doubled that of the 1.4 percent growth rate in personal spending for the previous quarter.
1、that后面的部分是用来解释修饰expectation的，而CDE中的of好像是有从属关系，而且of后面一般不加从句？所以排除了后三。 2、因为是expectation，所以还未发生，因此要加would.排除A

Whales originated in the freshwater lakes and rivers of ancient Asia about sixty million years ago.  Not until about ten million years later did species of whales develop specialized kidneys enabling them to drink salt water.  Although fossil evidence shows that some early whale species that lacked such kidneys sometimes swam in the Earth's saltwater oceans, these species must have had to return frequently to freshwater rivers to drink.

Half of the subjects in an experiment--the experimental group--consumed large quantities of a popular artificial sweetener.  Afterward, this group showed lower cognitive abilities than did the other half of the subjects--the control group--who did not consume the sweetener.  The detrimental effects were attributed to an amino acid that is one of the sweetener's principal constituents.
Which of the following, if true, would best help explain how the sweetener might produce the observed effect?
看选项快速排掉了A、C、E，剩下的B、D，最后选了D。 进入review再读一遍时就发现D不对劲了。但当读第一遍的时候，我认为B关于脑功能的描述、和D里also引出关于添加剂的说明，属于同一类事物——都是原文从未提及的；鉴于不可能回去重读，就在缺乏对差异的靠谱考查的情况下，以不可名状的标准剔掉了B。 之前录音讲排除D的方法是“看到also就感觉不大好”，但没提这句话的适用范围如何。 请老师讲解，在当时有什么快速可靠的做法能避免这样的错误。

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.
