"Argument assumes what it sets out to prove"

I've been drilling the Cambridge Flaw LR packet, in conjunction with the Trainer, and I keep seeing "argument assumes what it sets out to prove" as an answer choice. I've yet to find a question where that option was a correct answer, but would love to see how it would apply as a correct answer. Can anyone think of a question where such an answer choice is correct? I have every published LSAT so no test is off limits.

Thanks!

Refers to circular reasoning.....

Examples of this as a correct answer are a bit hard to come by. It pops up all the time as an incorrect answer, but only relatively rarely as a correct one. My theory is that that is simply because arguments with that flaw are a little difficult to write well unless the flaw is painfully obvious.

A good example, though, is PT49-S2-Q23.

are you some sort of machine that memorizes the exactly place where each question is or do you have a book infront of you?

The rumors of my robotic origins have been greatly exaggerated....


Actually, I just really find circular reasoning to be an interesting flaw, for precisely the reason I gave above - shows up all the time as an incorrect answer, only rarely as the correct answer. So, when I come across an example, I make a note. In my copy of PT49, I actually have a note above that question in big pink letters:
RARE CIRCULAR REASONING EXAMPLE!!


Yeah....I'm a geek.... :oops:

Nah, you LSAT-prep types are machines! But I agree - it's the "oddball" questions that stick with you. I once asked a tutor if there had ever been a game with a rule that could NOT be triggered because it would make the game unsolvable. He knew one right off the top of his head (although he did have to look up which test it was from), and I've never found another.

Too lazy to look it up, are we talking about the correll is a bad writer, we know because his writing sucks question?
Only pick this answer if you can damn well prove it. It's gotta be wrong 99.5% of the time.

When it comes up as a correct answer, it's almost always with the conclusion as the contrapositive of one of the premises.
