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 42

  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, tills 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 wanned 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.

Which of the following is closet in meaning to "frigid" in paragraph 1?

A. Rarely recorded

B. Extremely cold 

C. Never changing

D. Quite harsh

Đáp án D

Tất cả những điều dưới đây là đúng về khảo sát năm 1970 của Nam Cực ngoại trừ rằng ______

A. được tiến hành bằng không khí

B. sử dụng sóng vô tuyến điện

C. không đo kích thước chính xác của hồ

D. được điều khiển bởi vệ tinh

Hồ được phát hiện lần đầu tiên vào những năm 1970 trong khi một nhóm nghiên cứu đang tiến hành một cuộc khảo sát trên không của khu vực. Các sóng vô tuyến từ thiết bị khảo sát xâm nhập vào băng và cho thấy một phần nước có kích thước không xác định. 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.

aerial survey (= conducted by air),

radio waves penetrated the ice (made use of radio waves),

indeterminate size (could not determine the lake's exact size),
