Here's a question: The building could accommodate many people.  The entrance hall alone was impressive, being wide enough to admit a hundred shoulder to shoulder.  But the building was owned by a billionaire and used only for his personal entertainment.  How would you describe this place?

Here are possible answers to this question:
- convention center
- public building
- large building
- school
- town hall

I believe the correct choice is "large building", here's why:


the only building whose size is explicitly stated is the large building
