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.

A sudden increase in the production of elephant ivory artifacts on the Mediterranean coast of North Africa occurred in the tenth century.  Historians explain this increase as the result of an area opening up as a new source of ivory and argue on this basis that the important medieval trade between North Africa and East Africa began at this period.
 
Each of following, if true, provides some support for the historians' account described above EXCEPT:

Political Advertisement:
 
Mayor Delmont's critics complain about the jobs that were lost in the city under Delmont's leadership.  Yet the fact is that not only were more jobs created than were eliminated, but the average pay for these new jobs has been higher than the average pay for jobs citywide every year since Delmont took office.  So there can be no question that throughout Delmont's tenure the average paycheck in this city has been getting steadily bigger.
 
Which of the following, if true, most strengthens the argument in the advertisement?

Which of the following is included in the discussion of the cursorial hypothesis but not in the discussion of the arboreal hypothesis?
这道题的前一道题我读的第一段Archaeopteryx (the earliest known bird) and its后面所有内容，看这道题的问题说c理论里有，a理论里没有的内容。用必要性做题，因为前一道题我已经读了a理论的大部分，我自然去选项里挑a理论里没有的。又因为我在最开始读文章逻辑脉络的时候读了第一段前两句话，所以我依据第一段前两句和Archaeopteryx (the earliest known bird) and its后面所有内容直接做题，这样就只有最后一项没有，所以就选了E。 以前的录音都是挑c理论里面有的，不知道按我的做题思路为什么选不出C。 这是我读的内容，因为很多，只是看了看大概涉及哪方面：Two opposing scenarios, the "arboreal" hypothesis and the "cursorial" hypothesis, have traditionally been put forward concerning the origins of bird flight. The "arboreal" hypothesis holds that bird ancestors began to fly by climbing frees and gliding down from branches with the help of incipient feathers:（中间省略没读） Archaeopteryx (the earliest known bird) and its maniraptoran dinosaur cousins have no obviously arboreal adaptations, such as feet fully adapted for perching. Perhaps some of them could climb trees, but no convincing analysis has demonstrated how Archaeopteryx would have both climbed and flown with its forelimbs, and there were no plants taller than a few meters in the environments where Archaeopteryx fossils have been found. Even if the animals could climb trees, this ability is not synonymous with gliding ability. (Many small animals, and even some goats and kangaroos, are capable of climbing trees but are not gliders.) Besides, Archaeopteryx shows no obvious features of gliders, such as a broad membrane connecting forelimbs and hind limbs.

Although the restaurant company has recently added many new restaurants across the country and its sales have increased dramatically, its sales at restaurants open for more than a year have declined.
剩下了AC。语义差不多.. 找选项的区别。 发现A说restaurant company增加许多新的饭馆，用了主动，而C中用了被动。A更好.. 又发现A逗号后面是its，而C是the restaurant company‘s，C更加让对方明白。从这点来看觉得C更好。 请问一下老师.. 这样的两个选项怎么比才能快速拿下呢? 有点纠结~谢谢～

There are hopeful signs that we are shifting away from our heavy reliance on fossil fuels:  more than ten times as much energy is generated through wind power now than it was in 1990.
这道题是时间所剩不多的时候做的，当时读的是： 有一些什么信号是我们好像不依靠化石燃料了：超过10倍的和现在风产生的能源差不多 比 1990年的时候（不是特别明白） 比选项了，as..as AE干掉了，时间now 1990不太对应 干掉D, BC比，不同的在于第二个as后的内容，因为这个as..as和前面的more than时间紧没读太懂，当时第一反应是as much 一个名词 之后的as也应该跟一个名词性质的，所以选了B 希望老师能解答 谢谢

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 support the conclusion that some ingredient of the sweetener was responsible for the experimental results?
这是一套题的倒数第三道，时间压力很大，原文没细读，好像说了个实验组，控制组，然后有影响的原因是sweetener里面有aa。问题问支持，ACE明显无关，杀掉，剩下BD比较，D看不懂，而且要是支持原文结论得跟那个aa有点关系，就选了B。
