GMAT准备看OG时遇到逻辑CR不会,
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 mostseriously weaken the argument above?
(A) Satellites falling from orbit becauseof 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.
A为什么不对原文并没有提及钱选项提及不是不重合么

人造卫星只有在轨道上才能被维修,所以要求宇航员去维修.不修的话就会失常.因此要继续用飞船运送宇航员.
原文中维修就是隐形的钱,这是成本.A说卫星掉落在大气层会燃烧,这说明不了任何问题.

正确答案选e么

这题是考逻辑题。
1.satelltes的正常工作很重要（转播信息和分辨气候类型）-----》要是卫星故障了，必须要修好---->而卫星故障了，必须在轨道上修好---->结果（therefore）：必须继续派搭乘宇航员的航天器。
A说卫星故障，就会偏离轨道并掉入大气层烧毁，并不能驳斥“必须派送航天器”的结论，因此A选项和文章中的逻辑线没有关系。
E说 卫星过时了，修起来比发...

这题是考逻辑题。
1.satelltes的正常工作很重要（转播信息和分辨气候类型）-----》要是卫星故障了，必须要修好---->而卫星故障了，必须在轨道上修好---->结果（therefore）：必须继续派搭乘宇航员的航天器。
A说卫星故障，就会偏离轨道并掉入大气层烧毁，并不能驳斥“必须派送航天器”的结论，因此A选项和文章中的逻辑线没有关系。
E说 卫星过时了，修起来比发射新的卫星更贵----->发射新的卫星可以代替旧的卫星执行所需要的功能--->卫星不用修--->就不用派搭乘宇航员的航天器去（修理卫星了）。所以结论就被消弱了。
这样的解题思路还行吧。:)
