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.

D

Between 1980 and 2000 the sea otter population of the Aleutian Islands declined precipitously. There were no signs of disease or malnutrition, so there was probably an increase in the number of otters being eaten by predators. Orcas will eat otters when seals, their normal prey, are unavailable, and the Aleutian Islands seal population declined dramatically in the 1980s. Therefore, orcas were most likely the immediate cause of the otter population decline.

Which of the following, if true, most strengthens the argument?
题干要支持的信息：otter数量锐减，就是被orcas吃掉了。原文后面一些背景细节信息反复说证明otters就是被orcas吃掉的。A提到另一种生物是被otter吃的，完全内在逻辑链上 杀。B orcas也吃的seals不跟otters争食也不以otter为食，证明不了就是orcas吃掉的otter。杀。C 先放着 D orcas数量变化，跟是否orcas吃的otter无关。杀。E 捕鱼的多了 我这个瞎扯 杀。所以C根本没有在拎出逻辑链的那一刻对应上，至少杀出来了正确选项 请老师看我这么杀选项的逻辑可取吗 请纠正

Scientists typically do their most creative work before the age of forty. It is commonly thought that this happens because aging by itself brings about a loss of creative capacity. However, studies show that of scientists who produce highly creative work beyond the age of forty, a disproportionately large number entered their field at an older age than is usual. Since by the age of forty the large majority of scientists have been working in their field for at least fifteen years, the studies’ finding strongly suggests that the real reason why scientists over forty rarely produce highly creative work is not that they have aged but rather that scientists over forty have generally spent too long in their field.

In the argument given, the two portions in boldface play which of the following roles?
老师这道题我想问一下SC相关的知识，因为好多than相关的SC比较类题目我比较犯触，主要是不知该省哪些成分不该省哪些。还有就是动词的问题 我这道题第一个黑脸有than，than后面用了is，我疑惑了，因为煮鱼属a number of scientists，复数啊……所以这里是什么被省了导致谓语动词单数？还有，老师可以用您的经验告诉我一下做SC比较题than这种的时候常见的一些注意事项吗？谢谢啦！

Guidebook writer: I have visited hotels throughout the country and have noticed that in those built before 1930 the quality of the original carpentry work is generally superior to that in hotels built afterward. Clearly carpenters working on hotels before 1930 typically worked with more skill, care, and effort than carpenters who have worked on hotels built subsequently.

Which of the following, if true, most seriously weakens the guidebook writer’s argument?
老师我还是想问一下这道题涉及比较的SC可能考点。最后一句话，clearly carpenters working...worked with....（这是完整句子）than carpenters who....（这从句修饰的也是carpenters，这里就是一个sb.，而不是完整句子）如何能形成对比？谢谢老师解答！我做题时遇到类似的than前后成分是需要语义和语法都要平行并列的吧

Regardless of their form or function, all aerodynamically enhanced, curved objects made for throwing have been called boomerangs by non-Australians even since 1788, when Europeans saw Dharug-speaking men tossing "bumariny" in the area later known as Sydney.

Which of the following most logically completes the passage?
 
Appendicitis (inflammation of the appendix) is potentially fatal; consequently, patients with symptoms strongly suggesting appendicitis almost always have their appendix removed.  The appropriate surgery is low-risk but performed unnecessarily in about 20 percent of all cases.  A newly developed internal scan for appendicitis is highly accurate, producing two misdiagnoses for every 98 correct diagnoses.  Clearly, using this test, doctors can largely avoid unnecessary removals of the appendix without, however, performing any fewer necessary ones than before, since ______.
这道题逻辑链在做题时没有特别能体会出来选项要打的位置。我读的信息是：有阑尾炎症状的病人基本上都会被摘除阑尾，这种手术低风险但有好多手术没必要做。一项新的技术可以提高诊断的精确度从而降低误诊率，医生也就可以减少不必要的手术量了。因为---- A说的新技术确诊无阑尾炎的病人的医疗条件不如那些确诊有阑尾炎的。这个扯太远。杀。B 这项技术误诊情况经常是把有阑尾炎的说成没有阑尾炎---所以。不是阑尾炎的假象可以减少医生做多余的手术。就上原文 我所以这就类似于宁可少确诊一例，也不可误诊阑尾炎数量畸高。C 说所有确诊有阑尾炎的都是真实患有阑尾炎的。这个选项本来想选的，是不是也没说误诊率低的事情，所以这项没有贡献 是吗？

According to analysts, an alliance between three major personal computer companies and most of the nation's largest local telephone companies would enable customers to receive Internet data over regular telephone lines with speeds much higher than is currently possible.
错选D。我现在明白，是than前后比较对象不对应了，对吗？than后面不能直接currently possible。而要用be动词引出一个成分可以跟前面的speeds。杀with是因为with引不出来比较含义

Because she knew many of the leaders of colonial America and the American Revolution personally, Mercy Otis Warren was continually at or near the center of political events from 1765 to 1789, a vantage point combining with her talent for writing to make her one of the most valuable historians of the era.
