A student is taking a standardized test consisting of multiple choice questions for which there are five options for each question. Five points are awarded for each correct answer, but the student loses 2 points for an incorrect answer. Questions left blank neither receive nor lose points. What is the minimum number of options that the student should be able to rule out before making a guess on any particular question?

    Well, if the student was making a guess, then the answer would be c: none, this is because a student shouldn't be penalized for making a guess. :) But if we were talking about the number of options to rule out, it'd be four. :D
