<s>[INST] # Problem
You have 11 people in a room, including yourself. 10 of the people (not including yourself) are wearing either a red or blue hat, but you don't know what color it is. The people are lined up in a row, and you are at one end. You can ask one (and only one) person a yes or no question to figure out what color hat you're wearing. Who do you ask, and what do you ask them?[/INST]
