I get where you're going with this, but may want to rename the quiz to something other than "city" because a lot of these aren't represented by a city at all.
Here's what I mean:
Arizona is a state (not a city) - Cardinals play in Glendale
New York is a state - and technically the stadium is in NJ (but that's not the point)
Cowboys play in Arlington (not Dallas)
Carolina is technically 2 states until specified and the Panthers play in Charlotte
Patriots play in Foxborough.
Tennessee is a state, not a city - Titans play in Nashville
Minnesota is a state - Vikings play in Minneapolis.
