Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 38 to 45.

A rather surprisingly geographical feature of Antarctica is that a huge freshwater lake, one of the world's largest and deepest, lies hidden there under four kilometers of ice. Now known as Lake Vostok, this huge body of water is located under the ice block that comprises Antarctica. The lake is able to exist in its unfrozen state beneath this block of ice because its waters are warmed by geothermal heat from the earth's core. The thick glacier above Lake Vostok actually insulates it from the frigid temperature (the lowest ever recorded on Earth) on the surface.

The lake was first discovered in the 1970s while a research team was conducting an aerial survey of the area. Radio waves from the survey equipment penetrated the ice and revealed a body of water of indeterminate size. It was not until much more recently that data collected by satellite made scientist aware of the tremendous size of the lake; satellite -borne radar detected an extremely flat region where the ice remains level because it is floating on the water of the lake.

The discovery of such a huge freshwater lake trapped under Antarctic is of interest to the scientific community because of potential that the lake contains ancient microbes that have survived for thousands upon thousands of years, unaffected by factors such as nuclear fallout and elevated ultraviolet light that have affected organisms in more exposed areas. The downside of the discovery, however, lies in the difficulty of conducting research on the lake in such a harsh climate and in the problems associated with obtaining uncontaminated samples from the lake without actually exposing the lake to contamination. Scientists are looking for possible ways to accomplish this.

 

It can be inferred from the passage that the ice would not be flat if _____.

A. radio waves were not used

B. Antarctica were not so cold

C. There were no lake

Đáp án chính xác

A. sóng vô tuyến không được sử dụng

Thông tin ở câu: "It was not until much more recently that data collected by satellite made scientists aware of the tremendous size of the lake; the satellite-borne radar detected an extremely flat region where the ice remains level because it is floating on the water of the lake."

Cho đến gần đây, dữ liệu thu thập được từ vệ tinh đã làm cho các nhà khoa học nhận thức được tầm cỡ to lớn của hồ; radar vệ tinh phát hiện một vùng cực kỳ phẳng, nơi băng đá vẫn còn bằng phẳng vì nó trôi nổi trên mặt nước hồ.

Ta thấy tảng băng luôn cân bằng vì nó nổi trên mặt hồ do đó nếu không có hồ ở bên dưới thì tảng băng sẽ không thể cân bằng, do đó đáp án chính xác là đáp án C
