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.

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.

In a certain wildlife park, park rangers are able to track the movements of many rhinoceroses because those animals wear radio collars.  When, as often happens, a collar slips off, it is put back on.  Putting a collar on a rhinoceros involves immobilizing the animal by shooting it with a tranquilizer dart.  Female rhinoceroses that have been frequently recollared have significantly lower fertility rates than uncollared females.  Probably, therefore, some substance in the tranquilizer inhibits fertility.
 
Which of the following is an assumption on which the argument depends?
知道只有C沾边 但是觉得C选项像驳斥。 对C的理解是：母犀牛所经历的被固定对于生育是没有影响的。而原文中说tranquilizer 是限制生育的。

Boreal owls range over a much larger area than do other owls of similar size.  The reason for this behavior is probably that the small mammals on which owls feed are especially scarce in the forests where boreal owls live, and the relative scarcity of prey requires the owls to range more extensively to find sufficient food.
 
Which of the following, if true, most helps to confirm the explanation above?
觉得B只是把原文 “因为食物少而需要扩大活动区域找寻更多区域”重复了一遍。OG上不是说重复的内容不能作为答案么？

Which of the following most logically completes the passage?
 
On the whole, scientists do their most creative work before age forty, a tendency that has been taken to show that aging carries with it a loss of creative capacity.  An alternative explanation is that by age forty most scientists have worked in their field for fifteen or more years and that by then they have exhausted the opportunity for creative work in that field.  Supporting this explanation is the finding that ______.
我选的是D。 我觉得D的翻译是大于40岁的科学家们往往会在其他方面寻求满足感，比如XX或XX，比追求research。与原文超过40岁的人have exhausted the opportunity for creative work in that field相对应。 但是B不知道是怎么支持原文的。

A theory is either true or false.  Galileo's observations of Jupiter's satellites showed that the Ptolemaic theory of the motion of celestial bodies is false.  Therefore, since the Copernican theory of planetary motion is inconsistent with the Ptolemaic account, Galileo's observations of Jupiter's satellites proved the truth of the Copernican theory.
 
The argument above is open to the objection that it makes the questionable assumption that
听了之前的录音，英老师说问题是在驳斥。但是不知道E选项在驳斥什么 原文讲的是Galileo's observations of Jupiter's satellites proved the truth of the Copernican theory.证明了C这个人是正确的。E我觉得只是在重复原文，并没有驳斥什么。

Which of the following is true about Martin's theory, as that theory is described in the passage?
这道题我留下了A和B。 A：文章中6-7行，SK说“没有证据表明P这个东西狩猎大型生物，导致大型生物灭绝。” 这不就是说Martin认为大型生物灭绝跟P狩猎有关么。跟选项A的意思沾边儿 B：文中说“Krech also contradicts Martin's exclusion of climatic change as an explanation”。这说明Martin把气候变化导致灭绝这个因素排除了。感觉B也挺对的。 两个选项该怎么判断？
