Animals often _________________________. Reynold M. Yerkes,an animal scientist, gave a chimpanzee
a heavy box of sweetsmelling bananas. But the box was difficult for the animal to open.
Sniffing delightedly, the chimp tried to drag away the box so that he could work at leisure on the task of getting it open.
 It was too heavy, so he found another chimp, tapped him on the shoulder,
and gestured for help. Together, the two chimps easily moved the box, worked together at opening it, and shared the bananas.
 A chimpanzee, given food when chimps in adjoining cages were
left unfed, has been seen to pass a share of his delicacies through the bars.
 Sharing sometimes extends to giving help. A monkey with a sliver in his finger goes to another monkey, and the
“doctor” works as earnestly at the job as a human doctor.〔3점〕
