Read the following passage and mark the letter A, B, C, or D on your answer sheet to tát indicate the correct answer to tát each of the questions from 28 to tát 35. The xanh lơ whale is the largest animal ever known to tát have existed. During the 20th century, the species was almost exterminated due to tát 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 to tát 10 m longer phàn nàn males. And they can weigh up to tát 200 tonnes. Just to tát put that in perspective: an adult male African elephant weighs 6 tonnes. The xanh lơ 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 to tát their calls. Blue whales are the loudest animals on earth and their calls are louder phàn nàn a jet engine: reaching 188 decibels, while a jet's engine hit 'just' 140 decibels. Apart from their gigantic size, xanh lơ 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 Đen in color and range in length from 50 centimet in front to tát 100 centimet in back. Blue whales mostly travel alone or in groups of 2-3. Larger groups of up to tát 60 whales have been reported and are probably associated with feeding grounds. However, the xanh lơ 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 to tát us to tát be traveling alone may actually be in constant liên hệ with one another. At birth, a xanh lơ 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 to tát 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 to tát weaning, it represents a several billion-fold increase in tissue in just over a year and a half. Like other baleen whales, the xanh lơ whale has no teeth sánh it is hard to tát tell its age but scientists believe they live until at least 50. Like other large whales, xanh lơ 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 to tát move further south due to tát 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 to tát migrate further (perhaps 200-500 km more) to tát reach and feed at these food-rich areas where they build up reserves to tát 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.

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 to tát 10 m longer phàn nàn males. And they can weigh up to tát 200 tonnes. Just to tát put that in perspective: an adult male African elephant weighs 6 tonnes. The xanh lơ 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 to tát their calls. Blue whales are the loudest animals on earth and their calls are louder phàn nàn a jet engine: reaching 188 decibels, while a jet's engine hit 'just' 140 decibels. Apart from their gigantic size, xanh lơ 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 Đen in color and range in length from 50 centimet in front to tát 100 centimet in back. Blue whales mostly travel alone or in groups of 2-3. Larger groups of up to tát 60 whales have been reported and are probably associated with feeding grounds. However, the xanh lơ 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 to tát us to tát be traveling alone may actually be in constant liên hệ with one another. At birth, a xanh lơ 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 to tát 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 to tát weaning, it represents a several billion-fold increase in tissue in just over a year and a half. Like other baleen whales, the xanh lơ whale has no teeth sánh it is hard to tát tell its age but scientists believe they live until at least 50. Like other large whales, xanh lơ 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 to tát move further south due to tát 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 to tát migrate further (perhaps 200-500 km more) to tát reach and feed at these food-rich areas where they build up reserves to tát 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 to tát find food
