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 we 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 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.
(C) I would much rather be poor and respected than be rich and despised. 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.

OMG parallel reasoning questions always kill me! I'm never even 75% sure of my answer, so take everything I write with a mountain of salt.

I'm thinking A must be correct here, but again, I'm not sure. The initial argument is incorrect because it is a circular argument:

free ed is best ---> defend it because of X principle ----> because principle is good, then free ed is best

IMHO, A seems close to this as well:

I love music ---> listen to it all the time ---> I love music

But as I've said, I am not 100% sure about this! I am waiting for other opinions and the OA as well...

IMO : A ( not 100% sure )

Same line of reasoning as posted by DanaJ.

I didn't like the overall quality of the argument. The way data has been presented in split/incomplete sentences really frustrates me. there is, opportunity. Because
I am on a break !!

The original argument is a circular line of reasoning

(C1) Public education is the best kind of education so we must defend public education
(C2) Because we must defend public education, its the best kind of education

So look for an answer that has a circular line of reasoning

(a)

(C1) I love music and therefore listen to it constantly
(C2) I listen to my headphones all the time therefore I must love music

That seems to perfectly fit the argument structure! Not going to go through the rest because that works.

X is the best; X is based on Y. Y is worth defending, Therefore, X is the Best

I think B mimics the reasoning style of the passage the best

Books are Valuable. Books are like Friends. Friends are worth saving, so are books
Always borrow money from a pessimist, he doesn't expect to be paid back.

I like your explanations however (B) doesn't match what you originally laid out because it doesn't circle back around. If the argument went "Books are valuable. Books are like friends. Friends are worth saving and so are books. Anything worth saving is valuable and thus books are valuable" then you might have something.

Although you might ASSUME that anything valuable is worth saving (I know I do) its not stated.

in the question we have X so Y
Y = Z
Z so X (a circular argument)

In A, X so Y
Y restated
Y so X (also a circular argument)

Hence (A) wins

I also with A

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 we worth defending,
it is clear that free public education is better than any other form of education.

(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.


It seems to be that A follows same pattern.
