57. 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.

恩我觉得题干中的weak reasoning是public education 和 other forms 可以共存
所以我选了B
但答案是A 想不通呢~~

循环逻辑，结论和证据互相可以替代

It is a circular reasoning:

premise:Free public education is the best form of education there is

premise:Therefore, we must fight to ensure its continued existence; that is, we must be ready to defend the principle of equality of educational opportunity.

Conclusion:Because this principle is we worth defending, it is clear that free public education is better than any other form of education.

Both conclusion and premise state the same.

A tells the same

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

The premise and conclusion are different here.
C and D is the same as B

(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.

premise and conclusion are close but not same..
