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.

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.
全是黑体,什么个阵势...汗
想问的是E错在那里了呢?
还有这个anti-consideration中的consideration和我们讲的position有什么区别呢?
general situation 和
general principle有什么区别呢?
还要弱问的是
逻辑中所说的FACT和EVIDENCE有什么区别呢?是说EVIDENCE必须要有数据之类的么?
PRINCPLE又指的是什么呢?跟上面的两个有什么区别呢?
我真是黑体字白痴,一看这些就发懵
