4 Reading 2. Read the following passage and choose a correct answer
for each question. For many years people believed that the cleverest
animals after man were chimpanzees. However, there is proof that
dolphins may be even cleverer than these big apes. Although a dolphin
lives in the sea it is not a fish. It is a mammal. It is in many ways,
therefore, like a human being. Dolphins have a simple language. They
are able to talk to one another. It may be possible for man to learn how
to talk to dolphins. But this will not be easy because dolphins cannot
hear the kind of sounds man can make. If man wants to talk to dolphins,
therefore, he will have to make a third language with both he and the
dolphins can understand. Dolphins are also very friendly towards man.
They often follow ships. There are many stories of dolphins guiding
ships through difficult and dangerous waters.
