20. ___________ 21. ___________III. READING. (2.5 points - 0.25 /each)Read the following passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions.
Dolphins are mammals, not fish. They are warm blooded like man, and give birth, to one
baby, called a calf, at a time. At brith, a bottle-nose dolphin calf is about 90-130 cms long
and will grow to approximately 4 metres, living up to 40 years.
They are highly sociable animals, living in groups, called pods, which are fairly fluid, with
dolphins from other pods interacting with each other from time to time. Dolphins carry
their young inside their womb for about 12 months. The baby is born tail first, and its
mother will feed the calf for up to 2 years. However, the calf will stay with its mother for
between 3 and 6 years, during which time it will learn all about feeding techniques, social
interaction and group hunting.
