Final answer:
Rainsford sets three traps: the Malay mancatcher, the Burmese tiger pit, and the Ugandan knife trap, all designed to deter General Zaroff.
Step-by-step explanation:
The three traps that Rainsford sets for General Zaroff during the hunt include the Malay mancatcher, the Burmese tiger pit, and the Ugandan knife trap. The first one, the Malay mancatcher, is a weighted log that swings down when triggered. The second trap, the Burmese tiger pit, is a deep hole in the ground with sharp stakes at the bottom, covered with foliage to conceal it. The third and last trap, the Ugandan knife trap, involves a spring-loaded knife attached to a tree that would strike when Zaroff stepped on a triggering mechanism.
