Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the
correct answer to each of the questions from 46 to 50:
For many years, people believed that the cleverest animals after man were chimpanzees. Now,
however, there is proof that dolphins may be even cleverer than these big apes.
Although dolphins live in the sea, they are not fish. They are mammals. They are in many ways,
therefore, like human beings.
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
which both he and the dolphins can understand.
Dolphins are also friendly towards man. They often follow ships. There are many stories of
dolphins guiding ships through difficult and dangerous waters.
