I want to know the answer to the following question:
What is the name of the world's second largest indoor athletic building?
All the background I'm provided with is that "Yale has numerous athletic facilities, including the Yale Bowl (the nation's first natural "bowl" stadium, and prototype for such stadiums as the Los Angeles Memorial Coliseum and the Rose Bowl), located at The Walter Camp Field athletic complex, and the Payne Whitney Gymnasium, the second-largest indoor athletic complex in the world.". Is that enough to answer the question?
