question: Why do snakes have venomous bites?
distractor3: to scare humans
distractor1: to clean themselves
distractor2: to kill rival snakes
correct_answer: to kill prey
support: Some snakes have a venomous bite, which they use to kill their prey before eating it. Other snakes kill their prey by strangling them, and still others swallow their prey whole and alive. After eating, snakes enter a resting stage, while the process of digestion takes place. The process is highly efficient, with the snake’s digestive enzymes dissolving and absorbing everything but the prey’s hair and claws!.
