Previous "Name the Largest Cities" quizzes have visited such states as New York, Florida, and Washington. Today, we hit the nation's heartland: Missouri. This will be a tough one, for sure, since the lower part of the Top-10 dips into the 50,000-population range. (TWO HINTS: Three of the cities begin with the same prefix, and none of the 10 begins with the letter J.) A score of 5 or better (50 percent correct) should be considered a "win." Good luck!
