 I just wanted to know what... I bet you, I would bet money that the answer they're looking for is that it's a right. And if you said it's a privilege, they'd probably not accept you into the medical school because they would think that you don't care about the poor or you don't care about the little guy. So if I had to guess, checking the box that says it's a right, if those are the only two options, that's probably the answer they're looking for.
