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 following questions from 1 to 10 . The ocean bottom- a region nearly 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 6000 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 problem look like millions of years in the future. Today largely on the strength of evidence gathered during the Glomar .
