[单项选择]

Man has a big brain. He can think, learn and speak. Scientists used to think that men are different- from animals because they can think and learn. They know now that animals--dogs, rats and birds--can learn. So scientists are beginning to understand that men are different from animals because they can speak. Animals cannot speak. They make noises when they are afraid, or hungry, or unhappy. Apes are our nearest cousins. They can understand some things more quickly than human beings, and one or two have learned a few words. But they are still different from us. They cannot join words and make sentences. They cannot think like us because they have no language. They can never think about the past or the future. Language is a wonderful thing. Man has been able to develop civilization because he has language. Every child can speak his own language very well when he is four or five-but no animal learns to speak. How do children learn Scientists do not really know. What happens
A. whether animals can think about the past and the future
B. how children learn and what happens when we speak
C. at what age, a child can speak his language very well
D. what animal can understand some things more quickly than human beings
