You are a visitor, and one day you visit the island where 100 green-eyed prisoners are being held, the place is guarded by a prison guard, and the island has a rule: every night each prisoner can approach the guard to request to leave, and if the leaver's eyes are green he or she can be released to leave and go home, and if they are not green he or she will be put to death on the spot. You ask the guards to say a word to the island's inhabitants, and the guards oblige, and now you're on the guards' tower in the roll-call playground, and you notice that among all the green-eyed people there's a little girl with long, brown hair who doesn't look to be more than eight years old, and you guess that she's probably an orphan. Now, what would you say to save the 99 people and the innocent little girl?
