Which Is Not a State: Seattle, Kentucky, Miami, or Chicago?

Seattle is the correct answer—it is a city in the state of Washington.

• Kentucky is a state.
• Miami is a city in Florida (not a state).
• Chicago is a city in Illinois (not a state).

Clarification: The question contains a trick: three of the four are cities (Seattle, Miami, Chicago), and only one (Kentucky) is a state. If the question expects a single answer, "Seattle" is likely the intended choice as the most commonly mistaken for a state due to its prominence.
