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 NOT mentioned in the passage as being a result of the Deep Sea Drilling Project?
A. Geologists were able to determine the Earth’s appearance hundreds of millions of years ago.
B. Two geological theories became more widely accepted by scientists.
C. Geologists observed forms of marine life never before seen.
D. Information was revealed about the Earth’s past climatic changes.
Đáp án C.
Key words: result, Deep Sea Drilling Project
A. Geologists were able to determine the Earth’s appearance hundreds of millions of years ago: các nhà địa chất học đã có thể xác định được sự hình thành Trái Đất hàng triệu năm trước.
B.Two geological theories became more widely accepted by scientists: 2 học thuyết địa chất được các nhà khoa học chấp nhận rộng rãi.
C. Geologists observed forms of marine life never before seen: các nhà địa chất học quan sát các hình thức của sự sống dưới biển mà chưa bao giờ thấy trước đây.
D. Information was revealed about the Earth’s past climatic changes: thông tin về những thay đổi khí hậu trên Trái Đất được làm rõ.
Lưu ý đề bài yêu cầu tìm câu sai.
Đáp A đúng vì ở dòng 14 có “the Glomar Challenger’s core samples have allowed geologists to reconstruct what the planet looked like hundreds of millions of years ago”:những vật mẫu chính trên Glomar Challenge đã cho phép các nhà địa chất học tái hiện lại hành tinh hàng triệu năm về trước.
Đáp án B đúng vì ở dòng 17 có “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”: gần như tất cả các nhà khoa học trên thế giới đều đồng ý với học thuyết mảng kiến tạo và lục địa trôi dạt giải thích cho nhiều quá trinh địa lí hình thành nên Trái Đất.
Đáp án D đúng vì ở dòng 22 có “this record has already provided insights into the patterns and causes of past climatic change-information”: ghi chép này cho ta cái nhìn sâu sắc đối với mô hình và thông tin về những nguyên nhân của sự biến đổi khí hậu trong quá khứ.
Vậy đáp án chính xác là đáp án C.
