What kind of HELP do you need? You need to be specific when asking questions here.
If all you do is post your entire assignment, nothing will happen since no one here will do your work for you. But if you are specific about what you don't understand about the assignment or exactly what help you need, someone might be able to assist you.
For these kinds of questions, I'd go to http://www.answers.com and enter each term to find many meanings.
