【正确答案】 D

【答案解析】Chimpanzees are very intelligent and can learn extremely complex skills. They have sophisticated hunting strategies requiring cooperation, influence and rank. They are status conscious,manipulative and capable of deception. Chimpanzees in the laboratory can also master various kinds of skills including, to some extent, linguistic and numerical abilities. They can learn to use symbols and understand aspects of human language including some relational syntax, concepts of number and numerical sequence, and they are capable of spontaneous planning for a future state or event. Also they show skills in solving problems. For example, when they want to get bananas that are positioned out of reach, they would stack wooden crates to use as makeshift ladders in order to retrieve the food. If the bananas are placed on the ground outside of the cage, they would use sticks to lengthen the reach of their arms.
