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 43 to 52.

A rather surprising geographical feature of Antarctica is that a huge freshwater, 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 warned by geothermal heat from the earth’s core. This thick glacier above Lake Vostok actually insulates it from frigid temperatures (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 scientists 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 fresh water lake trapped under Antarctica is of interest to the scientific community because of the 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 conducting research on the lake in such a harsh climate and in the problems associated with obtaining uncontaminated sampled from the lake without actually exposing the lake to contamination. Scientists are looking for possible ways to accomplish this

It can be interfered from the passage that ice would not be flat if _______.

A. there were no lake

B. the lake were not so big

C. Antarctica were not so cold

D. radio waves were not used

C. không đo kích thước chính xác của hồ

B. Itcan be studied using radio waves: có thể nghiên cứu bằng sóng radio

mối quan tâm của cộng đồng khoa học vì có khả năng là hồ này chứa những vi khuẩn cổ đại đã sống hàng ngàn năm mà không bị ảnh hưởng bởi những yếu tố như bụi phóng xạ hạt nhân và ánh sáng tia cực tím cao

Dịch bài

Một đặc điểm địa lý đáng ngạc nhiên của Nam Cực là một hồ nước ngọt khổng lồ, một trong những hồ lớn và sâu nhất thế giới, nằm ẩn ở đó dưới 4 km băng. Bây giờ được biết đến như là Hồ Vostok, phần nước khổng lồ này nằm dưới khối băng bao gồm Nam Cực. Hồ có thể tồn tại trong trạng thái không đóng băng dưới khối băng này bởi vì nước của nó được làm nóng bởi địa nhiệt từ lõi của trái đất. Sông băng dày trên hồ Vostok thực sự cách ly nó khỏi nhiệt độ băng giá (thấp nhất từng được ghi lại trên trái đất) trên bề mặt của nó.

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.

Khám phá về một hồ nước ngọt khổng lồ bị mắc kẹt dưới Nam Cực là mối quan tâm của cộng đồng khoa học vì có khả năng là hồ này chứa những vi khuẩn cổ đại đã sống hàng ngàn năm mà không bị ảnh hưởng bởi những yếu tố như bụi phóng xạ hạt nhân và ánh sáng tia cực tím cao có ảnh hưởng đến các vi sinh vật ở những vùng tiếp xúc nhiều hơn. Tuy nhiên, điểm yếu của khám phá này là khó khăn trong việc tiến hành nghiên cứu về hồ trong điều kiện thời tiết khắc nghiệt và trong các vấn đề liên quan đến việc lấy mẫu không nhiễm khuẩn từ hồ mà không làm cho hồ bị ô nhiễm. Các nhà khoa học đang tìm kiếm những cách để thực hiện việc này.
