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.

        The ocean bottom- a region nearly 2.5 times greater than total land area of the Earth- is a vast frontier that even today is largely unexplored and uncharted. Until about a century ago, the deep-ocean floor was completely inaccessible, hidden beneath waters averaging over 3,600 meters deep. Totally without light and subjected to intense pressures hundreds of times greater than at the Earth’s surface, deep-ocean bottom is a hostile environment to humans, in some ways as forbidding and remote as the void of outer space.

        Although researchers have taken samples of deep-ocean rocks and sediments for over a century, the first detailed global investigation of the ocean bottom did not actually start until 1968, with the beginning of the National Science Foundation’s Deep Sea Drilling Project (DSDP). Using techniques first developed for the offshore oil gas industry, the Dad’s drill ship, the Glomar Challenger, was able to maintain a steady position on the ocean’s surface and drill in very deep waters, extracting samples of sediments and rock from the ocean floor.

        The Glomar Challenger completed 96 voyages in a 15-year research program that ended in November 1983. During this time, the vessel logged 600,000 kilometers and took almost 20,000 core samples of seabed sediments and rocks at 624 drilling sites around the world. The Glomar Challenger’s core samples have allowed geologists to reconstruct what the planet looked like hundreds of millions of years ago and to calculate what it will look like millions of years in the future. Today, largely on the strength of evidence gathered during the Glomar Challenger’s voyages, nearly all earth scientists agree on the theories of plate tectonics and continental drift that explain many of the geological processes that shape the Earth.

        The cores of sediment drilled by the Glomar Challenger have also yielded information critical to understanding the world’s past climates. Deep-ocean sediments provide a climatic record stretching back hundreds of millions of years, because they are largely isolated from the mechanical erosion and the intense chemical and biological activity that rapidly destroy much land-based evidence of past climates. This record has already provided insights into the patterns and causes of past climatic change-information that may be used to predict future climates

Which of the following is true of the Glomar Challenger?

A. It is a type of submarine.

B. It has gone on over 100   voyages.

C. It made its first DSDP voyage in 1968.

Đáp án chính xác

D. It is an ongoing project.

Đáp án C.

Key words: Glomar Challenger

Clue: the first detailed global investigation of the ocean bottom did not actually start until 1968, with the beginning of the National Science Foundation’s Deep Sea Drilling Project (DSDP). Using techniques first developed for the offshore oil gas industry, the Dad’s drill ship, the Glomar Challenger, was able to maintain a steady position on the ocean’s surface and drill in very deep waters: chuyến thám hiểm đầu tiên xuống đáy đại dương một cách kỹ lưỡng không thực sự bắt đầu cho đến tận năm 1968 cùng với sự khởi đầu của Dự án khoan đáy biển sâu của Quỹ khoa học quốc gia (DSDP). Sử dụng kỹ thuật lần đầu tiên được phát trin đ phục vụ ngành công nghiệp xăng dầu ngoài khơi, con tàu khoan Dad’s, hay Glomar Challenger, đã có thể duy trì vị trí thăng bằng trên mặt bin và khoan xuống mực nước rất sâu.

A. It is a type of submarine: nó là một loại tàu ngầm

B. It has gone on over 100 voyages: nó đã thực hiện 100 chuyến đi biển

C. It made its first DSDP voyage in 1968: nó thực hiện chuyến đi biển DSDP đầu tiên vào năm 1968

D. It is an ongoing project: nó là một dự án đang din ra

Dễ thấy đáp án chính xác là đáp án C.
