WHAT IS THE CORRECT ANSWER, AND ONLY GIVE THE CORRECT ANSWER... OR ELSE.
Are you threatening us? Or else what? You'll fail? You'll leave the site? Just a little tip, threatening people when you have absolutely nothing to threaten them with, doesn't make you look very bright.
We don't do homework questions on this site. We're willing to help if you put in some effort, but more effort than simply typing your question to a thread, is needed.
You have a computer, so Google. You can read, so open the book. That's where the answer to your question is. You'll just have to put in some effort, do the work, which will make you a better person in the long run.
