I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "The Museum of Osteology houses more than 300 real animal skeletons. Focusing on the form and function of the skeletal system, this 7,000 sq ft (650 m2) museum displays hundreds of skulls and skeletons from all corners of the world. Exhibits include adaptation, locomotion, classification and diversity of the vertebrate kingdom. The Museum of Osteology is the only one of its kind in America."? 

What is the third word in USA?
