Answer 15

I think what @abb0t means by 'HAHA! Wow.' is that you need to do your own work. You're supposed to come here for help, not just getting the answers. If you did't learn this in class, then you should have asked for help, and understand about what you are SUPPOSED to be learning. I'd suggest you read the code of conduct, and follow it, before you get in trouble.
