Method of Reasoning questions ask you to describe HOW an argument makes its case — its structure and technique — not whether that technique is any good. Confusing this with Flaw questions, which DO evaluate quality, is a common and avoidable source of errors.
A Method of Reasoning answer choice might read “the argument proceeds by ruling out all alternatives except one” — this is simply TRUE or FALSE as a description of what the argument does, regardless of whether ruling out alternatives was actually a good strategy in this case.
Many arguments that use a flawed technique still get correctly described by a Method of Reasoning answer choice that names the technique neutrally, without commenting on whether it worked. If you're evaluating quality instead of just checking accuracy of description, you can reject a correct answer because the technique it describes seems weak — when the question never asked you to judge that.
For Method of Reasoning answer choices, ask only: “did the argument actually DO this?” — not “was this a good way to argue?” The second question belongs to a different question type entirely.
Method of Reasoning questions are, at their core, testing whether you can step back from an argument's content and describe its shape — the same abstraction skill Parallel Reasoning rewards, applied here to structural description rather than structural matching.
