Read the following passage and mark the letter A, B, C, or D on your answer sheet lớn indicate the correct answer lớn each of the questions from 28 lớn 35. The xanh xao whale is the largest animal ever known lớn have existed. During the 20th century, the species was almost exterminated due lớn commercial whaling. The species has slowly recovered following the global whaling ban but it remains endangered and faces a number of serious threats including ship strikes and the impact of climate change. Blue whales are simply enormous with most ranging in length from 24-30 m. The largest ever recorded was a gargantuan 33.5 m long. Females are up lớn 10 m longer than vãn males. And they can weigh up lớn 200 tonnes. Just lớn put that in perspective: an adult male African elephant weighs 6 tonnes. The xanh xao whale's heart is the size of a small siêu xe and its beat can be detected two miles away. But that's nothing compared lớn their calls. Blue whales are the loudest animals on earth and their calls are louder than vãn a jet engine: reaching 188 decibels, while a jet's engine hit 'just' 140 decibels. Apart from their gigantic size, xanh xao whales can be identified by their relatively small dorsal fin, a fairly rounded rostrum (anterior part of the skull), and approximately 90 ventral grooves, which reach the navel. They also have row of 300-400 baleen plates on each side of the mouth, which are Black in color and range in length from 50 centimet in front lớn 100 centimet in back. Blue whales mostly travel alone or in groups of 2-3. Larger groups of up lớn 60 whales have been reported and are probably associated with feeding grounds. However, the xanh xao whale has the most powerful voice in the animal kingdom and its low-frequency sounds can travel in deep water over hundreds, or even thousands, of miles. Under these circumstances, animals which may appear lớn us lớn be traveling alone may actually be in constant liên hệ with one another. At birth, a xanh xao whale calf is the largest baby on earth: approximately 8m long and weighing about 4 tonnes. They grow at a rate of 90 kilogam per day and wean after 7-8 months, once they have reached about 15 m in length, and are able lớn follow the normal migration pattern alone. They reach sexual maturity at 5-10 years. This growth rate is astonishing and is probably the fastest in the animal kingdom. From conception lớn weaning, it represents a several billion-fold increase in tissue in just over a year and a half. Like other baleen whales, the xanh xao whale has no teeth so sánh it is hard lớn tell its age but scientists believe they live until at least 50. Like other large whales, xanh xao whales are threatened by chemical and sound pollution, habitat loss, overfishing of krill, ship strikes and becoming entangled in fishing gear. Climate change could also have a major impact on its food supply, since global warming and associated ocean acidification may impact krill populations. In addition, frontal zones - critical whale habitats - are projected lớn move further south due lớn climate change. Frontal zones are boundaries between different water masses, where water can rise from the depths, bringing with it large amounts of nutrients that stimulate the growth of phytoplankton and tư vấn substantial populations of prey species for whales. Blue whales would have lớn migrate further (perhaps 200-500 km more) lớn reach and feed at these food-rich areas where they build up reserves lớn sustain themselves for the rest of the year. These longer migration paths could increase the energy costs of migration and reduce the duration of the main feeding season. As frontal zones move southward, they also move closer together, reducing the overall area of foraging habitat available.

Because it can liên hệ with others through their powerful voice. C. Because it shares the same feeding grounds with others. D.

They reach sexual maturity at 5-10 years. This growth rate is astonishing and is probably the fastest in the animal kingdom. From conception lớn weaning, it represents a several billion-fold increase in tissue in just over a year and a half. Like other baleen whales, the xanh xao whale has no teeth so sánh it is hard lớn tell its age but scientists believe they live until at least 50. Like other large whales, xanh xao whales are threatened by chemical and sound pollution, habitat loss, overfishing of krill, ship strikes and becoming entangled in fishing gear. Climate change could also have a major impact on its food supply, since global warming and associated ocean acidification may impact krill populations. In addition, frontal zones - critical whale habitats - are projected lớn move further south due lớn climate change. Frontal zones are boundaries between different water masses, where water can rise from the depths, bringing with it large amounts of nutrients that stimulate the growth of phytoplankton and tư vấn substantial populations of prey species for whales. Blue whales would have lớn migrate further (perhaps 200-500 km more) lớn reach and feed at these food-rich areas where they build up reserves lớn sustain themselves for the rest of the year. These longer migration paths could increase the energy costs of migration and reduce the duration of the main feeding season. As frontal zones move southward, they also move closer together, reducing the overall area of foraging habitat available. Question 31: What does the word "wean" in paragraph 4 mean? A. stop feeding a calf with its mother's milk B. stop growing as fast as before C. begin living independently D. begin trying lớn find food
