标题: Hele me analyze one question on feifei Note-->babypace转移

感染了t病的人总是反复的发作，由此证明，t病从来没有被根治过

问假设？

A)t病不可能被完全根治

B)......

C)......

D)......

E)病人不会反复的感染t病

答案是E，为什么A不对。难道A不是一个很好的假设吗？如何排除这种答案。

另外在逻辑题中

premise,assumption,evidence是什么概念？premise=assumption or premise=evidence?

对这个题及逻辑术语不是很明白。哪位能帮忙看看吗？先谢谢了！！！

If A is possible, it is only a conclusion reasoned out on the basis of provided information.

it is not a assumption.

a premise is the idea or statement on which reasoning is based.

assumption is thing accepted as ture or as sure to happen, but not proved.

evidence is information that gives you a reason for believing sth or proves sth.

Say,

I am rich (evidence or premise)

Rich people tend to be happy (assumption or premise)

I am probably happy (conclusion)

Thanks a lot for your help!

很簡單

如果結論是Ｔ從來沒有被根治過, 那什麼情況一定會發生？反覆的發作的這個動作, 對不對？

所以, 如果Ｔ從來沒有被根治過, 必然Ｔ會反覆的發作。

那逆反命題為何？如果Ｔ沒有反覆的發作, Ｔ必然根治了。

你的Ｅ答案完全就是我們必要假設的逆反命題。

Premise - supports and evidence in any forms submitted by the author to establish the claim

Assumption - precondition must be true to ensure the argument airtight.
