"Hello," said the Troll. "How may I help you?"

"Well," you replied. "I really would like to find my way out of this maze."

"I know how to reach the end. In fact," said the Troll, "I will take you if you would like."

"Very much, thank you!"

"Of course, you'll need to answer three questions first. If you answer all three correctly, I'll show you the way out. But," the Troll added, "if you anwer any of the questions incorrectly, you'll never find your way out."
