Answer 15

FYI it's not a good idea to use this site for quizzes and tests. Best thing to do is to ask questions regarding general topics. Then someone can walk you through how to solve it, so you can do the next one on your own. If you have questions, or are in the middle and are stuck you can certainly ask where to go from there, or where you got stuck, or why you're not getting the right answer.
