3 and 4 have no info, so they are out.
1 can see two hats and if they were the same color, then he'd know what color his own hat is and would shout it out. But they aren't and he doesn't.

Next hard puzzle (harder than the last one).

A prisoner is in a room with two doors. One door leads to freedom, the other to death. Each door has a guard. The guards know each other and know which door leads to freedom. One guard always speaks the truth, the other always lies. *There is no relationship between which guard is at which door. It is completely random.*

Given all this information, the prisoner is allowed to ask one question. What should the question be in order for him to find his way to freedom.
