I'm at work right now, and we've got some down time, so I am filling out this beast too. I answered every question. It says do you consider your self disadvantaged. I said no, I don't consider myself disadvantaged. It said did you come from a community where the majority of dental care was government funded. I said no, I don't come from such a community. It said how many people lived in your house. I said 6.
I didn't see anythign that said "only answer these questions if you were disadvantaged" so I answered all of them. I'm pretty sure that's what they want.
