Question 6: Read the following passage and choose the best answer. Write your answers in the numbered blanks provided below the passage. (20point)

In addition to the great ridges and volcanic chains, the oceans conceal another form of undersea mountains: the strange guyot, or flat-topped seamount. No marine geologist even suspected the  existence of these isolated mountains until they were discovered by geologist Harry H. Hess in 1946.   He was serving at the time as naval officer on a ship equipped with a fathometer. Hess named these truncated peaks for the nineteenth-century Swiss-born geologist Arnold Guyot, who had served on the faculty of Princeton University for thirty years. Since then, hundreds of guyots have been discovered in every ocean but the Arctic. Like offshore canyons, guyots present a challenge to oceanographic theory. They are believed to be extinct volcanoes. Their flat tops indicate that they once stood above or just below the surface, where the action of waves leveled off their peaks. Yet today, by definition, their summits are at least 600 feet below the surface, and some are as deep as 8,200 feet. Most lie between 3,200 feet and 6,500 feet. Their tops are not really flat but slope upward to a low pinnacle at the center. Dredging from the tops of guyots has recovered basalt and coral rubble, and that would be expected from the eroded tops of what were once islands. Some of this material is over 80 million years old. Geologists think the drowning of the guyots involved two processes: The great weight of the volcanic mountains depressed the sea floor beneath them, and the level of the sea rose a number of times, especially when the last Ice Age ended, some 8,000 to 11.000 years ago.

Volcanoes have been erupting on the earth for millions of years. More than five hundred of them still erupt today. These are called active volcanoes. Volcanoes are located in belts or chains. They are found where the earth’s crust is weak. The weak spots let the hot rock escape when the volcano erupts.

Many volcano belts are mountain ranges along the edges of continents. One belt runs along the western coast of South America up through the western part of the United States. Other volcanoes are found in ocean basins.

About three-fifths of all active volcanoes in the world are in the Pacific Ocean. Many of these volcanoes erupt under the water. The Hawaiian Islands were built by volcanoes that began erupting under water and finally reached the surface of the ocean.

Other young volunteers go and work in the homes of people who are sick or old. They paint, clean up, or repair their houses, or the shopping or mow their lawns. For boys who no longer have fathers there is an organization called Big Brothers. College students and other men take these boys to baseball games or on fishing trips and help them to get to know things that boys usually learn from their fathers. Each city has a number of clubs where boys and girls can go and play games or learn crafts. Some of these clubs show movies or organize short trips to the mountains, the beaches, museums or other places of interest. Most of these clubs use a lot of high school and college students as volunteers because they are young enough to understand the problems of younger boys and girls. Volunteers believe that some of the happiest people in the world are those who help to bring happiness to others.

On July 20 , 1969 , that dream came true . Two American men landed on the moon . Their names were Neil Armstrong and Edwin Aldrin .
The first thing the men was that the moon is covered with dust . The dust is so thick that the men left footprints where they walked . Those were the first marks a living thing had ever made on the moon . And they could stay there for years and years . There is no wind or rain to wipe them off .
The two men walked on the moon for hours . They picked up rocks to bring back to us for study . They dug up dirt to bring back . They set up machines to find out things people wanted to know . Then they climbed back into their moon landing craft .
Next day the landing craft roared as the two men took off from the moon . They joined Micheal Collins in the spaceship that waited for them above the moon . Then they were off on their long trip back to earth .
Behind them they left the plains and tall mountains of the moon . They left the machines they had set up . And they left footprints that may last forever .

Countries around the world have begun to deal with the problem in ..........(vary) ways. Some countries, in order to circumvent the problem, have allocated large amounts of land to animal reserves. They then charge admission to help defray the costs of maintaining the parks and they often must also depend on world organizations for support. With the money they get, they can invest in equipment, and patrols to protect the animals. Another solution that is an attempt to stem the tide of animal extinction is an international boycott of products made from endangered species. This seems fairly effective but it will not, by itself, prevent animals from being hunted and killed.
