I removed the ref tags. (I say "tags" because there was a closing tag in addition to the opening tag, but the closing tag wasn't formatted correctly, and it was misplaced at the end of the profile instead of the end of a footnote.) And I inserted ref tags around one of the cited sources to show what a footnote should look like. But I'm not sure if I put it in the right place, because I couldn't tell for sure which text was supposed to go with which source. If I guessed wrong, please move the footnote!
