Philosophy paper - Part I

I am currently in the middle (and by middle, I mean 1/5 started) of a 5-page philosophy paper about mental states in the opinion of David M. Armstrong. Do you see just how confusing that sounds! And you don't even know the topic (1. explain what Armstrong thinks mental states are, 2. explain how Armstrong argues for this view, 3. Discuss whether Armstrong's view is correct or not.)

As it is already 10:52 p.m. here in Los Angeles, I hope to finish before my friends on the east coast wake up for class.
