Hi!
The assigned audience for the classification and division essays is Penn Foster students. You should direct your topic ot as broad a cross section of your peers as possible.
There are a couple of reasons for this: first, if you have to write to people who don't know about your topic, you'll naturally write more. Many students have trouble meeting the minimum length of a writing assignment, so if you imagine that your writing to an audience that needs more explanation, instruction or definition, it will help you to flesh out your paper.
Second, there is some basic logic at play: why would you write to an audience that already knows about your topic? This is an expository - or informative - essay, so your purpose is essentially to teach your readers something they didn't know before.
I hope this helps, but please feel free to write back with more questions if you have them.
Best,
