狒狒逻辑宝典上一道题目,听听大家讲法。

 Free public education is the best form of education there is. Therefore, we must fight to ensure its continued existence; that is, we must be ready to defend the principle of equality of educational opportunity. Because this principle is well worth defending, it is clear that free public education is better than any other form of education.

Which one of the following illustrates the same weak reasoning as found in the passage?

(A) I love music, and that’s why I listen to it constantly. I have my stereo or radio on every waking minute. Since I lay music all the time, I must really love it.

(B) Books are my most valuable possessions. My books are like my friends---each pleases me in different ways. Just as I would give up everything to save my friends, so too with my books.

(C) I would much rather be poor and respected than be rich and despises. To have the respect of others is far more valuable than to have millions of dollars.

(D) I have never been betrayed by any of my friends. They have been true to me through good times and bad. Therefore I will never betray any of my friends.

(E) Because every plant I have ever seen has green leaves, I have concluded that all plants must have green leaves. This looks like a plant but it does not have green leaves, so it cannot be a plant.

Correct answer is A.

但是不晓得为什么是A。请NN们指教下。

原题逻辑:

因为,(X)Free public education is the best  ---->所以,  (Y) defend the principle of equality of educational opportunity.

因为,(Y)worth defending -----> 所以,(X)free public education is better than any

(A)选项逻辑:

因为,(X) I love music----->所以,(Y) listen to it constantly.

因为,(Y)I lay music all the time----->所以,(X) I must really love it.

谢谢LS的回复。

会不会是因果颠倒的逻辑问题?

我不太明白什么属于“因果颠倒的逻辑问题”,不过,这道题的因果确实是颠来到去。

把原因当成了结果,把结果当成了原因。

我觉得是循环论证,我分析的逻辑链如下:
Free public education is the best form of education=>fight to ensure its continued existence=>defend the principle of equality of educational opportunity(this principle is well worth defending)=>free public education is better than any other form of education.
最后有原因推到了原因
A的论证过程如下:
love music=>listen to it constantly(lay music all the time)=>really love it
应该说是原因结果循环着换吧,说不清哪个是结果那个是原因的,只能说论证的起点和论证的终点一样了
