5 questions from work

On Thursday, I was asked no less than 5 (five) questions by my coworkers.

-What is the difference between tangerines and oranges?
-How many lunches did you order for the product demo?
-Can we fit the elevator in that shaft anyway?
-The elevation is off by 1/8th of an inch, is that okay?
-Is my son Owen bothering you?

Guess which one didn't I answer totally sarcastically.
It's a trivia quiz for you.
Kind of like Sukodoh, but with letters.
