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.

Dịch câu hỏi: Tác giả nói đáy đại dương cũng tương tự như một “frontier”/ “vùng hẻo lánh, không ai sinh sống, chưa được đặt chân tới” (nghĩa trong bài) vì:
Dịch các phương án:
A. Vì nó không phải là một khu vực nổi tiếng thường được nghiên cứu khoa học.
B. Vì nó chứa rất nhiều cá thể sống.

Thông tin dẫn chứng tìm thấy ở đoạn 1 dòng 1 phần thống tin chứa từ “frontier”. “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?”
Đáy đại dương, một vùng có diện tích lớn gấp 2.5 lần toàn bộ diện tích đất liền trên Trái Đất- là một vùng biên giới rộng lớn, phần mà ngày nay phần lớn vẫn chưa được khám phá và khảo sát.
Dễ dàng loại bỏ B và C.
A thiên về ý vùng này không được các nhà khoa học yêu thích nghiên cứu trong khi đó đáy biển là một nơi chưa biết đến do chúng ta chưa thể khám phá được. Vì vậy đáp án D là phù hợp nhất

Parents whose children show a special interest in a particular sport have a difficult decision to (33) _____________about their childrens career, should they allow their children to train to become top sportsmen and women? For many children it means starting very young and school work, going out with friends and other interests have to take second place.
