Final answer:
Rainsford sets up the Uganda Knife Trap as a defense against General Zaroff in "The Most Dangerous Game."
Step-by-step explanation:
In the short story "The Most Dangerous Game" by Richard Connell, Rainsford sets up the Uganda Knife Trap as a way to defend himself against General Zaroff, who is hunting him. The trap consists of a large knife attached to a sapling, which is bent over and held in place with a trip wire. When the trip wire is triggered, the sapling springs up, releasing the knife and potentially injuring or killing the person who triggered the trap.
