关于boldface题的问题

在boldface 9 真题里，我有一些逻辑术语不明白。请教各位！
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.
(参考答案: B）
我选择了A. general consideration , anti-consideration 是什么意思？能举个例子吗?
====================================================
还有一个问题是句中出现的premise和 assumption 是同义的吗？

谢谢！

答案A 的第二句 有问题。The second boldface in the argument 并没有反对第一句的 Principle, 而只是第一句要求的条件不可以实现。

据个例子（应用前辈的）来说什么是Consideration:
Evidence：A survey showed that MBA can earn high salary
consideration:　Is MBA worthy of money?
conclusion:　I　should earn MBA.

In this argument, the consideration of the first part is: 　the drug will have no various effects on the patients’ bodies, and we will unaware of... --> the double-blind test study is most effective way...

我个人感觉 consideration is much like a judement, which could serve as an evidence for conclusion. (either support or weaken). Therefore, it seems unreasonable to say＂general consideration"

premise is a sufficient condition, while assumption is a required condition.
