Câu hỏi: Read the following passage and choose the letter A, B, C orD to indicate the correct answer for each of the blanks.
The ocean bottom - a region nearly 2.5 times greater than the total land area of 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 Earths surface, the 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 Foundations Deep Sea Drilling Project (DSDP). Using techniques first developed for the offshore oil and gas industry, the DSDP'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 probably 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.
The author mentions "outer space" because_____________
A. the Earth's climate millions of years ago was similar to conditions in outer space.
B. it is similar to the ocean floor in being alien to the human environment.
C. rock formations in outer space are similar to those found on the ocean floor.
D. techniques used by scientists to explore outer space were similar to those used in ocean exploration.

Dịch câu hỏi: tác giả đề cập đến "outer space" bởi vì____________
Dịch các phương án:
A. Khí hậu của Trái Đất hàng triệu năm về trước giống với điều kiện ở ngoài vũ trụ.
B. Nó giống như đáy đại dương ở điểm nó hoàn toàn xa lạ với môi trường sống của loài người.
C. Sự hình thành đá ở ngoài vũ trụ cũng tương tự như sự hình thành đá ở đáy đại dương.
D. Những kĩ thuật mà các nhà khoa học dùng để tìm hiểu vũ trụ cũng tương tự như kĩ thuật dùng trong việc thám hiểm đại dương.
Dẫn chứng nằm ở đoạn 1 dòng 4,5,6 phần có chứa từ outer space. "Totally without light and subjected to intense pressures hundreds of times greater than at the Earth's surface, the deep-ocean bottom is a hostile environment to humans, in some ways as forbidding and remote as the void of outer space."
Hoàn toàn không có ánh sáng và chịu áp lực khủng khiếp gấp hàng trăm lần so với ở bề mặt Trái Đất, đáy đại dương là một môi trường thù địch với con người, theo một cách nào đó thì nó là vùng cấm xa xôi và bí hiểm như không gian vũ trụ".
Như vậy đọc phần dịch dẫn chứng, ta có thể chọn B là phương án phù hợp nhất.
