Here's a question and a few possible answers: 

Q: John wrote a religions tract and decided to give them away.  He felt that he should go somewhere where he could reach a large and diverse group from many places.  Where is he likely to distribute his tracts?
Possible A: public place, airport, subway car, shopping mall, laundromat

Why is "airport" an answer aligned with human common sense?
