Read the following passage and identify the main idea and its three major supporting details.

1Chimpanzees, skillful tool users, use several objects found in their environment as tools. 2First of all, they use sticks. 3They have been seen inserting carefully trimmed sticks into termite mounds and then withdrawing the sticks and eating the termites that cling to them. 4The chimps usually lick one end of the stick to make it sticky, poke it into the termite mound, and then withdraw it covered in termites. 5Chimps are also known to use sticks to steal honey from beehives. 6In addition, chimps use leaves in a variety of ingenious ways. 7For example, they have been seen rolling leaves into cones to use as drinking cups, dampening them, and using them to clean their bodies, and chewing them until they can serve as sponges. 8Finally, chimpanzees have been observed using stones to crack open nuts.
