Câu hỏi: Read the passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.
Since water is the basis of life, composing the greater part of the tissues of all living things, the crucial problem of desert animals is to survive in a world where sources of flowing water are rare. And since man's inexorable necessity is to absorb large quantities of water at frequent intervals, he can scarcely comprehend that many creatures of the desert pass their entire lives without a single drop.
Uncompromising as it is, the desert has not eliminated life but only those forms unable to withstand its desiccating effects. No moist-skinned, water-loving animals can exist there. Few large animals are found. The giants of the North American desert are the deer, the coyote, and the bobcat. Since desert country is open, it holds more swift-footed running and leaping creatures than the tangled forest. Its population is largely nocturnal, silent, filled with reticence, and ruled by stealth. Yet they are not emaciated. Having adapted to their austere environment, they are as healthy as animals anywhere else in the word.
The secret of their adjustment lies in the combination of behavior and physiology. None could survive if, like Mad dogs and Englishmen, they went out in the midday sun; many would die in a matter of minutes.
So most of them pass the burning hours asleep in cool, humid burrows underneath the ground, emerging to hunt only by night. The surface of the sun-baked desert averages around 150 degrees, but 18 inches down the temperature is only 60 degrees.
Man can hardly understand why many animals live their whole life in the desert, as _________
A. water composes the greater part of the tissues of living things
B. sources of flowing water are rare in a desert
C. water is an essential part of his existence
D. very few large animals are found in the desert

Kiến thức: Đọc hiểu
Giải thích: Con người không thể hiểu tại sao nhiều động vật sống suốt đời ở sa mạc, bởi vì __________
A. nước chứa thành phần quan trọng của các mô của các sinh vật sống
B. nguồn nước chảy thì hiếm ở sa mạc
C. nước là phần quan trọng cho sự sống
D. rất ít động vật lớn được tìm thấy trên sa mạc
Thông tin: And since man's inexorable necessity is to absorb large quantities of water at frequent intervals, he can scarcely comprehend that many creatures of the desert pass their entire lives without a single drop.
Tạm dịch: Và vì nhu cầu không thể thay đổi được của con người là hấp thụ một lượng nước lớn trong khoảng thời gian thường xuyên, con người hiếm khi có thể hiểu rằng nhiều sinh vật trên sa mạc vượt qua toàn bộ cuộc sống của chúng mà không cần một giọt.
