Think Thursday with the crew here at the mentalfloss.com Brain Game. Today's challenge: What do the most populous cities in these four states (but no others) have in common?

MISSOURI, NEW YORK, OKLAHOMA, UTAH

Here is the ANSWER.

THE ANSWER:

They are each named "CITY" - Kansas City (MO), *New York City (NY), Oklahoma City (OK), and Salt Lake City (UT).

*Some argue that the official city name is "New York" and not "New York City," so if you missed today's challenge as a result, consider your answer (or lack of an answer) correct.
