Final answer:
Orangutans are generally solitary animals and do not live in large multi-male multi-female groups, making the statement false.
Step-by-step explanation:
The statement that orangutans tend to live in large multi-male multi-female groups is False. Unlike gorillas and chimpanzees which usually live in groups with multiple males and females, orangutans are known for their more solitary lifestyle. While there have been observations of orangutans being more social than once thought, particularly from the work of primatologist Carel van Schaik, their typical behavior is not the formation of large multi-male multi-female groups. Orangutans tend to be arboreal and solitary, with the males being larger than the females and living separately except for mating and child-rearing.
