VI. 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.                                                                            
After two decades of growing student enrollments and economic prosperity, business schools in the United States have started to face harder times. Only Harvard's MBA School has shown a substantial increase in enrollment in recent years. Both Princeton and Stanford have seen decreases in their enrollments. Since 1990, the number of people receiving Masters in Business Administration (MBA) degrees, has dropped about 3 percent to 75,000, and the trend of lower enrollment rates is expected to continue.
 
There are two factors causing this decrease in students seeking an MBA degree. The first one is that many graduates of four-year colleges are finding that an MBA degree does not guarantee a plush job on Wall Street, or in other financial districts of major American cities. Many of the entry-level management jobs are going to students graduating with Master of Arts degrees in English and the humanities as well as those holding MBA degrees. Students have asked the question, "Is an MBA degree really what I need to be best prepared for getting a good job?" The second major factor has been the cutting of American payrolls and the lower number of entry-level jobs being offered. Business needs are changing, and MBA schools are struggling to meet the new demands.
The word "prosperity" in line 1 could be best replaced by which of the following?
 
A.success   
B.surplus   
C.nurturing                   
D.education

  Langston Hughes was one of the greatest American writers of the 20th century. He was born in Joplin, Missouri, and moved to Cleveland at the age of 14. Several years later, he spent one year in Mexico before attending Columbia University in New York. For a few years after that, he roamed the world as a seaman, visiting ports around the world and writing some poetry. He returned to the United States and attended Lincoln University, where he won the Witter Bynner Prize for undergraduate poetry. After graduating in 1928, he travelled to Spain and to Russia with the help of a Guggenheim fellowship. His novels include Not without Laughter (1930) and The Big Sea (1940). He wrote an autobiography in 1956 and also published several collections of poetry. The collections include The Weary Blues (1926), The Dream Keeper (1932), Shakespeare in Harlem (1942), Fields of Wonder (1947), One Way Ticket (1947), and Selected Poems (1959). A man of many talents, Hughes was also a lyricist, librettist, and a journalist. As an older man in the 1960s, he spent much of his time collecting poems from Africa and from African-Americans to popularize black writers. Hughes is one of the most accomplished writers in American literary history, and he is seen as one of the artistic leaders of the Harlem Renaissance, the period when a neighbourhood that was predominantly black produced a flood of great literature, music, and other art forms depicting daily city life for African-Americans.

Furthermore, all three fossil 'fuels are non-renewable forms of energy. Geothermal power is unlikely ever to be an energy source of major importance. It is limited and is exploitable in only a few places. Hydro-power offers a much more useful source of energy. It is also renewable but its (38) ______ is limited. Dams cannot be built in certain areas. In addition, large dams are also capable of causing changes in the world's climate. Wind power is a pollution – free source of renewable energy but it cannot be used in many parts of the world where there is (39) ______ wind. Wave power is better source of energy in certain ways but it is clearly not practicable to build dams across every river estuary or to cover seas with expensive equipment. It is also ineffective where the sea is usually calm. Solar power is renewable, it does not cause pollution and it does not add to the earth's heat load. Unfortunately, solar power is not distributed equally, and in the northern latitudes it is difficult to (40) ______ and store. Solar power' also requires expensive equipment. Finally, nuclear power provides a very efficient and renewable power source.
