You are in a room all by yourself. The walls, floor, and ceiling are white. Up on the ceiling is a trapdoor. On the far wall is a closed metal door with a hook attached to the top of its frame. Leaning against the left wall is a ladder. On the right corner of the far wall is a long coil of strong rope. In the center of the room is a waist-high spool with three handles extending horizontally off it like parts of the letter Y. What do you do?
