Number one, so you don't get bamboozled into picking the one that is correct for another question but then really looking for, you know, opposite answers and throwaway answers. The last strategy that I didn't go over that I'm going to give to you which is maybe the worst one ever but it works sometimes is the thumbs up, thumbs down question or strategy. If you read a question like you read this one about Stalin, it even says a negative effect of Stalin. So that's easy. You can figure it out. That means the answer has got to be thumbs down. So then look at the answers up there.
