1. Modern navigation systems, which are found in most of today’s commercial aircraft, are made with low-power circuitry, which is more susceptible to interference than the vacuum-tube circuitry found in older planes. During landing, navigation systems receive radio signals from the airport to guide the plane to the runway. Recently, one plane with low-power circuitry veered off course during landing, its dials dimming, when a passenger turned on a laptop computer. Clearly, modern aircraft navigation systems are being put at risk by the electronic devices that passengers carry on board, such as cassette players and laptop computers.
The two portions in boldface play which of the following roles?
(A) The first is a principle that the argument relies on and the second is a conclusion that can be drawn from the first.
(B) The first is a fact that argument relies on and the second is a conclusion that must be drawn from this argument.
(C) The first acknowledges a consideration that supports that main position; the second is that conclusion.
(D) The first is an evidence that supports the conclusion, the second is that conclusion.
(E) The first is a principle that is necessary for this argument, the second is a conclusion that could be drawn from this argument.
Principle, evidence, consideration, fact 在本题中有什么区别吗？

BF 1.
(E) The first is a principle that is necessary for this argument, the second is a conclusion that could be drawn from this argument.
第一句不是一个明显的EVIDENCE吗？ 怎么会是一个PRINCIPLE呐？
我认为PRINCIPLE是用来扰乱视线的。 答案D更MAKES SENSE。
CONSIDERATION， PRICINPLE 都不应该作为句子的ROLE。

2. A double-blind study, in which neither the patient nor the primary researcher knows whether the patient is being given the drug being tested or a placebo, is the most effective procedure for testing the efficacy of a drug. But we will not be able to perform such a study on this new drug, since the drug will have various effects on the patients’ bodies, which will make us aware of whether the patients are getting the drug or a placebo.
The two portions in boldface play which of the following roles?
(A) The first is a general consideration that introduces the argument; the second is a special situation that weighs against the first.
(B) The first is a general principle that is necessary for this argument; the second is an anti-consideration that the argument includes.
(C) The first is a premise that this argument includes; the second is a main idea that can be drawn from this argument.
(D) The first is an evidence that this argument includes; the second is a conclusion that can not be drawn from this argument.
(E) The first is a general situation that supports this argument; the second is a conclusion that can be drawn from a special fact.
A中， AGAINST 有问题
B中 ANTI-CONSIDERATION 有问题。
C， 好像没有问题。
D中，the second is a conclusion that can not be drawn from this argument. 显然不对。
E中，general situation好像也不能算句子的作用。

3. The interstitial nucleus, a sub-region of the brain’s hypothalamus, is typically smaller for male cats than for female cats. A neurobiologist performed autopsies on male cats who died from disease X, a disease affecting no more than 0.5 percent of male cats, and found that these male cats had interstitial nuclei that were as large as those generally found in female cats. Thus, the size of the interstitial nucleus determines whether or not male cats can contract disease X, but, the hypothalamus is known not to be causally linked to disease Y, and disease X is a subtype of disease Y.
The two portions in boldface play which of the following roles?
(A) The first is a fact in support of the consideration that is one of two points of this argument; the second is the alternative point that weighs against the first.
(B) The first is an evidence that supports the consideration that the argument includes; the second is the fact that weighs against that consideration that could be drawn from the first.
(C) The first is a general principle that is against the conclusion; the second is that conclusion.
(D) The first is an evidence that supports the conclusion; the second is an exceptional example.
(E) The first is a fact in support of the conclusion that the argument depends on; the second is a fact that is against the first one.
这个题比较怪。 整篇文章是来推THUS后的那句话，也就是CONCLUSION。在后又撂出一个FACT(EVIDENCE)来否定整个ARGUMENT。但BUT之后的句子不应看作一个结论，只能是一个反EVIDENCE而已。 如果这样来理解此文的话，答案不难推出：E。
A，C都把第二句作为CONCLUSION了。
B中的CONSIDERATION 有问题。
D中的EXCEPTIONAL EXAMPLE 也不正确。

3.(E) The first is a fact in support of the conclusion that the argument depends on; the second is a fact that is against the first one.
The second is not against the first one. It's aginist the consideration based on the first one.

I pick B. I think "consideration" is the right word here...
