Question 17-20: Read the following passage and circle the letter A, B, C or D to indicate the answer to each of the following questions.
For many years, people believe that the cleverest animals after man were chimpanzees. Now, however, there is proof that dolphins may be cleverer than chimpanzees. Although dolphins live in the sea, it is not fish. It is an animal 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 can‘t hear the man‘s sound. If man wants to talk to dolphins, he will have to make the third language both man and dolphins understand. Dolphins are also very friendly toward man. They often follow ships.
There are many stories of dolphins guiding ships through difficult and dangerous water.
