Read the passages below and answer the question that follow by choosing the most appropriate of the options lettered A — E
A right female whale can be as long as 16 meters long, about the size of an articulated bus, and weighs up to 80 tons! Its massive body is generally black, sometimes with white patches on the belly. The head is enormous, a quarter of the entire body length. The mouth is long and arched. The right female whale has no dorsal fin as do some other species. To swim forward, it flexes its broad and deeply notched tail up and down, instead of side to side as fish do. To change direction, it moves its flippers similar to the way an airplane is steered.
Curiously, despite their immense proportions, right whales have considerable flexibility, performing some amazing acrobatics. You can see them sailing, the tail sticking out of water for long periods; lobtailing, raising the tail and slapping the water hard; and breaching, thrusting themselves out of water and then falling back with a great splash that can be seen from far away.
