Professor Palutena, make Challenge 3 a 'make a challenge' challenge.
Or, make it a merge into two teams challenge, and have a 10 question quiz, where the first two people to finish are the team captains.
Eventually you will have to merge us into either two teams, or no teams. I suggest once we reach either 18, or 16 people we merge. Then merge us back into teams when there are 6 of us
