Question: I heard that there’s ancient treasure buried in an inconspicuous corner of the snow plains. Sampo the explorer – Tall, Blue, and Handsome – found the treasure after quite an adventure, and before them, they found two talking gates: One gold, one silver. One of these two doors only tells the truth, while the other only tells lies. Behind one of these doors lies a treasure, behind the other lies an ancient monster. A note on the treasure map advises: The two doors will only answer one question.
The quick-witted Sampo – Tall, Blue, and Handsome – gives it some thought before asking the silver door,
“What would the gold door say about the thing that lies behind you?”
The silver door answers, “It would say, there is treasure behind me.” Which door should Sampo – Tall, Blue, and Handsome – open?
