For NA questions, some of the answers are SA and NA together. I'm having trouble with this because there are other "trap" choices that I choose that wreck the argument and look correct. I can identify the SA answer, but i think it is wrong because it is too strong.
My question is: If there is a SA answer choice for an NA question, is it right every time? How can I tell when they're looking for both when it is not indicated in the question stem?
