What's your answer?

We don't do homework on this site. This is your assignment, and you have to put in more effort than re-writing it and expecting someone else to do it for you.

So give us your answer, and we'll go from there. But don't expect anyone on this site to do the work for you, that's not how life works.

As Alty said, we help, but don't do the work for you. Post your answer and then you'll get help from us.
