Green eyesLogic Level pending
On an Island there is a brutal regime; All 100 inhabitants wish to escape. The leader of the regime has told them that if a green eyed inhabitant comes to him, they will be set free. Anyone else coming to him will be put to death. The inhabitants can come to him only at night, when they are separated form the other inhabitants (assuming they aren't coming to see the leader).
All 100 inhabitants are extremely cautious, perfect logicians and most importantly green eyed. There are no reflective surfaces on the island and none of the inhabitants can ask another what colour their own eyes are but they can see everyone elses.
A diplomat comes to the Island and the leader tells her that she may issue one statement, under the condition that it doesn't give any residents new information. Which of these options would tell the residents enough to let them leave without breaking this rule.
