I could help you, but I will not give you the answer. I'll help you, but that means you must first tell me what you think the answer is and then comment and I'll help you refine. We'll start with that you understand and we'll build on that. I'm not going to just do your homework for you because you're too lazy to do yourself, but I'll help if you put a little effort yourself.
