Think of a topic you know a lot about.  Imagine you need to give two presentations.  Presentation one will be given to an audience that has a deep understanding of your topic and presentation two will be given to an audience that knows nothing about your topic.  have one paragraph representing how you would explain your topic to people who come with a deep understanding of your topic and have a second paragraph representing how you would explain your topic to an audience who knew little to nothing about your topic.  Finally, explain how you used language differently in each paragraph.
