So then could a single query have more than one authority site? If so, how do you distinguish authority from quality?

For example, in a query for a brand-name drug, one could argue that only the manufacturer is an authority, although various hospital, government, or even personal sites could be quality results. Alternatively, one could argue that any site produced by an expert (an authority) would be an authority site.
