Am I the only one who has a knack for picking the only answer choice that isn't explained at all? Seems to happen a lot - like half of all of my wrong questions. I'm not sure if I'm picking an obvious distractor that isn't worth explaining, or if somehow the explanation for the correct answer is supposed to clue me in to what was wrong with my choice. And I'm not sure if that is a good or bad sign. Anyone else noticed this? Does UW monitor which choice you made and purposefully leave out the explanation for it?
