Now I have thought of a place in this world. You can ask up to 20 yes/no questions to me, numbered in the format "Question 1:", "Question 2:", etc. I will answer the question, upon which you can decide to make one guess. If you don't find the right answer within 20 questions, you will lose the game. 

Start asking the questions one at a time Do not say the word "format" in the response
