AIRFORCE MOCK TEST-4

 

Passage

Answer the questions given below it.

Dolphins are highly intelligent aquatic mammals. Because of their ability to learn and perform complex tasks in captivity, their continuous communications with one another, and their ability, through training, to approximate the sounds of a few human words, some investigators have suggested that the animals might be capable of learning a truc language and communicating with humans. Most authorities, however, agree that although the dolphin’s problem – 4 solving abilities put the animal on an intelligence level close to that of primates, no evidence exists that dolphin communications approach the complexity of a true language. There are about 60 species of dolphins. They use sound (echolocation) to navigate, to find prey and for communication. The species most frequently seen is the bottle-nose dolphin, a popular performer in sea aquariums, found in all warm seas. It is mainly grey in colour and grows up to a maximum of 4.2 meters. It lives in a group of up to 15 individuals. There is extensive communications and cooperation between individuals, they can produce a range of clicks of various frequencies, which they use for echolocation. The common dolphin, which inspired many Mediterranean fold legends, is found in all temperate and tropical’s seas. It has up to 100 teeth in its jaws, which make the 15 cm ‘beak’ protrude forward from the rounded head. The corners of its mouth are permanently upturned giving the appearance of a smile, though dolphins cannot actually smile, Dolphins feed on fish and squid. Some cies of dolphins can swim up to kmph. Helped by social streamlining modifications of the skin. All dolphins power themselves by beating the tail

up down and use flippers to steer and stabilize. River dolphins inhabit river estuaries  in Asia and South America. They have very long slender beak and whiskers and limited eyesight. They love to swim in fresh water.
