Let's say you were trapped inside this room. Inside this room
were 2 doors, and 2 caged talking - tigers. One of the
doors was an exit into the paradise. The other was an
exit into a bottomless pit- (In other words, if you opened
this door, you'd fall until your insides get ripped apart by
the G-forces- actually you'd still fall- Anyway...)
Since these tigers talked, you could ask them questions.
Actually, you could ask one question (to either Tiger) because
if you asked more than one, both cages would disentegrate, and
the Tigers would devour you. Anyway, one of the tigers
always told theh truth. One always told a lie.
How would you go about getting safely out of the room?
