    All of the following are true about the 1970 survey of Antarctica EXCEPT that it _____

    • A. was conducted by air
    • B. made use of radio waves
    • C. could not determine the lake's exact size
    • D. was controlled by a satellite

    Lời giải tham khảo:

    Đáp án đúng: D

    Dẫn chứng: 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; the satellite-borne radar detected an extremely flat region where the ice remains level because it is floating on the water of the lake.
