以下是引用许仙在2008-2-13 14:18:00的发言:上CR题: Robot satellites relay important communications and identify weather patterns. Because the satellites can be repaired only in orbit, astronauts are needed to repair them. Without repairs, the satellites would eventually malfunction. Therefore, space flights carrying astronauts must continue.
Which of the following, if true, would most seriously weaken the argument above?
(A) Satellites falling from orbit because of malfunctions burn up in the atmosphere. (B) Although satellites are indispensable in the identification of weather patterns, weather forecasters also make some use of computer projections to identify weather patterns. (C) The government, responding to public pressure, has decided to cut the budget for space flights and put more money into social welfare programs. (D) Repair of satellites requires heavy equipment, which adds to the amount of fuel needed to lift a spaceship carrying astronauts into orbit. (E) Technical obsolescence of robot satellites makes repairing them more costly and less practical than sending new, improved satellites into orbit. 答案是E,不明白啊~ 这题的结论是:要继续用太空飞船送宇航员去修理卫星。 而问题是:下面哪一个WEAKEN这个观点。 答案E是说:修理更贵。而且还没有送一个新的,技术更新的上去来得实际。 那意思就是说----没有必要送宇航员去修理了。 前面几个答案说的都不太相关。
我是这么做逻辑的。题看得懂大致就能做对;不懂,就错的很惨了。
