Robot satellites relay improtant communications and identify weather patterns.Because the satellites can be repaired only in orbie , astronauts are needed to repair them.Without repairs, the satellites would eventually malfunction. Therefore, space flights carrying astronauts must continue.
Witch of the following, if , would most seriously weaken the argument above?
A Satellites falling from orbit because of malfunctions burn up in the atmosphere.
B Although satellites are indispenable 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 prssure , 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 amout of fuel needed to life a spaceship carrying astronauts into orbit.
E Tehinical obsolescence of robot satellites makes repairing them more costly and less practical than sending nes, improved satellites into orbit.

答案：E
可我觉得A也对啊，卫星因为坏了掉下去了，所以不用上去修了
可是OG解释是：this tells uw that a malfunction can destroy the satelite--information that provides some additional support to the argume
既然说是加强？？
好迷茫啊...

A. This tells us that a malfunction can destroy the satellite-information that provides some additional support to the argument.
我觉得OG是想说，malfunction 会毁灭satellite, 而原文说 Because the satellites can be repaired only in orbit,所以一定要上去修，更不能让它掉下来，从某种程度上来说，支持了arguement ---- Therefor, space flights carrying astronauts must continue.所以不选A。
