Based on a true story

So I'm just curious. Hypothetically, I give Twilight a test for her to take and inform her that there is only one right answer. The first question says "You are at a restaurant. The server gives you a menu and asks you what you will have to drink. Your friend has ordered a coke. What drink do you order?"
A) Coca-cola
B) Pepsi
C) Lemonade
D) Water

If Twilight reacts similar to how my friend reacted, then she'd freak out and say that out of all her study materials she wasn't prepared for this question. Based on this reaction, I can easily foresee Princess Celestia asking her this question as a part of a "test" to see if she's Princess material.
