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.

According to a study published in The New England Journal of Medicine, aspirin prevents blood clots just as well as a commonly used and more expensive blood-thinning drug does.
请问金老师，AE之间该怎么做选择呢，难道只是因为简洁性吗，在ae之间犹豫很久，觉得e在语法错误上没有，而且觉得e中药物在……方面表现的很好比a的药物阻止blood clots意思更好…

In general, jobs are harder to get in times of economic recession because many businesses cut back operations.  However, any future recessions in Vargonia will probably not reduce the availability of teaching jobs at government-funded schools.  This is because Vargonia has just introduced a legal requirement that education in government-funded schools be available, free of charge, to all Vargonian children regardless of the state of the economy, and that current student-teacher ratios not be exceeded.
 
Which of the following, if true, most strengthens the argument?
在B，C中纠结。 觉得B说的是经济强的时候，有25%的儿童在私立学校上学，那有75%的在公立学校，75%比例算挺高的，所以公立学校老师也本来比较多。所以如果经济变差，读私立学校的可能会转到公立学校，相应的公立学校的老师需求会更多，所以可以推出经济衰退，公立学校老师数量不会下降。但好绕。 C说的是与最近一次经济衰退相比，公立学校老师的数量上升了，所以经济衰退不会影响公立学校老师的数量，挺直接的。是不是因为currently所以不对，我感觉一些题目除非所有选项都出现currenrtly或者其他一样的时间，要不一般情况下这种选项都不对。不知道这种感觉对不对。 另外，我想知道像这样逻辑题的原因部分有两个或以上的原因，做题的时候要怎么关注重点？还是说strenghthen argument 重点应该在其结论，就是只要能够支持经济衰退不会影响公立学校老师的岗位就行。

Electronic computer chips made of tiny silicon wafers now regularly contain millions of electronic switches.  Unfortunately, electronic switches that are this small cannot withstand intense radiation.  Micro-Mechanics plans to produce a chip that, because it uses only microscopic mechanical switches, will be invulnerable to radiation damage.  The switches will, however, be slower than electronic switches and the chip will contain only 12,000 switches.
 
For there to be a market for Micro-Mechanics' chip as a result of the apparent advantage described above, each of the following would have to be true EXCEPT:
这道题做完以后看答案是可以理解的，但是我觉得在考试的紧张情况下，我会为了节省时间，看到C选项的switches uesd on electronic chips that contain 12000就会直接排除，因为原文electronic chips包含的是millions switches，而包含12000switches的是MM的芯片，我会觉得与原文不符，直接就选了，像我这种情况怎么办呢
