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.

In response to mounting pubic concern, an airplane manufacturer implemented a program with the well-publicized goal of reducing by half the total yearly amount of hazardous waste generated by its passenger-jet division.  When the program began in 1994, the division's hazardous waste output was 90 pounds per production worker; last year it was 40 pounds per production worker. Clearly, therefore, charges that the manufacturer's program has not met its goal are false.
 
Which of the following is an assumption on which the argument depends?
A说nonhazardous waste，范围错，杀 B说什么passenger jets的生产数量什么的，也明显不对 C说other division和原文范围不符，杀 我选了D，虽然也没觉得D怎么就对了。。。 E选项觉得很诡异，因为文中说的90pounds还有40pounds都是per production worker,E 说工人的数量没有明显变少觉得好像跟结论没啥关系，求解答。。。

Beta Corporation claims that it no longer has enough work for the 60 computer data-entry workers that it is laying off.  These workers have heard, however, that the company is buying 100 new computers.  So the workers concluded that the company's real reason for laying them off is to fill their jobs with lower-paid workers.
Which of the following, if true, would most undermine the workers' conclusion?
选了C，C中说要求所有资料被存放在电脑化的文件，所以买新电脑用来储存…就削弱了结论。不知道有没有人这么想呢？这算是哪种发散？

Astronomer:  Observations of the Shoemaker-Levi comet on its collision course with Jupiter showed that the comet broke into fragments before entering Jupiter's atmosphere in 1994, but they did not show how big those fragments were.  Nevertheless, some indication of their size can be inferred from spectrographic analyses of Jupiter's outer atmosphere.  After the fragments' entry, these analyses revealed unprecedented traces of sulfur.  The fragments themselves almost certainly contained no sulfur, but astronomers believe that the cloud layer below Jupiter's outer atmosphere does contain sulfur.  Since sulfur would have seeped into the outer atmosphere if comet fragments had penetrated this cloud layer, it is likely that some of the fragments were at least large enough to have passed through Jupiter's outer atmosphere without being burned up.
 
In the astronomer's argument, the two portions in boldface play which of the following roles?
之前录音中说两处BF都是论据。但是我做题的时候觉得第一处BF是说了一个发现，后面是解释为什么会出现这种情况。所以看选项时只看对first的表述，选了E。求老师解答！！ Astronomer: Observations of the Shoemaker-Levi comet on its collision course with Jupiter showed that the comet broke into fragments before entering Jupiter's atmosphere in 1994, but they did not show how big those fragments were.

The first is a claim that the astronomer seeks to show is true; the second provides evidence in support of the truth of that claim. The first and the second are each considerations advanced in support of the conclusion of the argument. The first provides evidence in support of the conclusion of the argument; the second is that conclusion. The first is a circumstance for which the astronomer seeks to provide an explanation; the second acknowledges a consideration that weighs against the explanation provided by the astronomer.

The passage suggests that if the movement of capital in the world were restricted, which of the following would be likely?
这是gmat3366的分析，和我做题的思路一摸一样，过去发布的讲解现在不能听了。请老师讲讲吧。 1.问题问的是，如果世界上资本移动受到限制的话，下面哪一个会发生？ 2.原文定位，第一遍做题时，只在文章的最后一句话中扫到了有资本移动的信息，定位到最后一句，但是最后一句说的是现在资本移动很自由（不受限）所以有意识的控制货币价值很难。 3.看选项。排除了A B E因为根本就没收货币价值的事儿，C D比，C强调的是币值和平均工资的关系；D强调的是币值和生产力的关系。这两个选项根据定位到的最后一句话选不出来，于是就又向前倒了一句，谈的是工资，所以选了C。 整个思路在哪一步错了呢？

The primary purpose of the passage is to
1.看完原文逻辑脉络，留下了A,E两个选项。 2.比选项差异，我把关注点留在了explanations和implications上，认为A选项说的是，对一个已知现象的解释；E说的是一个研究发现说明了什么。 3.根据第二段的逻辑脉络，“考虑到对这个发现的解释，科学家排除了什么，拒绝了什么，排除了什么，他们认为最有可能的解释是什么.”最后选了A. 4.虽然觉得A中的well-known fact不好，但是感觉A的整体意思比E好一些，故把E杀了。 请老师看看我这样思考哪里错在哪里了，十分感谢。
