A good number of hints. Nothing very fancy though – mostly common sense.
The classic puzzle: "Imagine that you’re in a game show and your host shows you three doors. Behind one of them is a shiny car and behind the others are far less lustrous goats. You pick one of the doors and get whatever lies within. After making your choice, your host opens one of the other two doors, which inevitably reveals a goat. He then asks you if you want to stick with your original pick, or swap to the other remaining door. What do you do?"
Very interesting case. Living among them would be totally disorienting. Thank goodness we can count.
