Explanation: About Sloth: Sloths sleep for almost 17 hours per day. That leaves only nine hours to lumber through the trees. They maintain a low body temperature of about 86°F to 93°F. They move in and out of the shade to regulate their body temperature. The sloth eats the leaves of the same tree on which it lives. It hardly needs anything else. When it has eaten enough leaves from that tree, it moves to the nearby tree. Sloths live for about 40 years. During that time they move around only eight trees. Once a week it comes down from the tree to relieve itself. Thus, (A) A sloth spends almost 20 hours a day sleeping while hanging upside down on a tree branch - Incorrect (B) A sloth eats the leaves of the same tree on which it lives. It hardly needs anything else - Correct (C) Sloths life is about 20 years and in that time it moves around only two trees - Incorrect
