Answer:Reasoning: The Sun bear's natural hunting behaviors and significantly stronger physical attributes (claws, bite force) give it a clear advantage in a direct confrontation. The Gelada's teeth, while capable of inflicting pain, are unlikely to deter a determined bear, especially a hungry one. The Gelada's lack of familiarity with the forest environment further weakens its chances. Even if the bear isn't hungry, its size and intimidating presence would probably be enough to scare the Gelada away. Therefore, the Sun bear is more likely to win, unless the encounter is a brief, accidental one.
