Solution for #20

Alternate Solution #1

A blind man enjoys walking near a cliff and uses the sound of a buoy to gauge his distance from the edge. One day the buoy's anchor rope breaks, allowing the buoy to drift away from the shore. When it rings, the man thinks he's further away from the edge than he is, walks over it, and falls to his death.

Alternate Solution #2

The man is a bell ringer. One day the rope breaks, and he falls down the shaft and dies.
