What actress shared hosting Jeopardy until Ken Jennings took over full-time?

What undrafted African-American quarterback was inducted into the Pro Football Hall of Fame in 2006?

What name is shared by the currency of Panama, a fictional county in Veronica Mars, and #7 on AFI's list of movie heroes?

What country's flag is identical to neighboring Romania's except for a superimposed coat of arms?
