Here's a question and a few possible answers: 

Q: John's took his appointment book with him to a checkup but couldn't find it anywhere. He looked and he looked but he didn't know where it was.  It wasn't until he bought a new one, went home, took a shower that he found it.  Where was it?
Possible A: office supply store, wallet, doctor's office, handbag, pocket

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