110. 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?

(B) Although satellites are indispensable in the identification of weather patterns, weather forecasters also make some use of computer projections to identify weather patters.

(E) Technical obsolescence of robot satellites makes repairing them more costly and less practical than sending new, improved satellites into orbit.

key:e,b为什么不行呢？有别的方法测天气，就不需要继续送人上天了，这不是weaken结论吗？请赐教，谢谢。

你没有看懂选项，阅读方面需要提高。（B）没有说有别的方法替代卫星，只是说在使用卫星的同时，有时还借助电脑来预测天气。

hi zex,

i would not choose B b/c it ask for the "most seriously weaken" choices. B certainly is one of the "weaken" choices, as far as i can see, but not as strong and relative as E present.

hope that helps...

i agree. thanks

B不对。本题推理过程的FOCUS在宇航员是否必要，而不是卫星是否必要。而且，B同意了卫星是必不可少的，即使按ZCX的说法有别的方法，也不能削弱卫星的必要性。

同意 B中说了卫星是不可替代的

因为可以用新的更加先进而且更加经济的卫星去代替老的卫星。

所以，没有必再要保留载人飞船。

about C Og says:

While budget cut for space flights provide a context for the argument
in favor of
continuring flights, this statement does not weaken the argument.

为什么说削减预算是in favor of 呢？感觉是不利于继续飞行的呀。。。。

是啊！！对于选项ｅ没有疑问，但是再一次看选项ｃ时，也觉得会weaken，减少经费-->没有办法继续飞行，

我本来以为cut the budget for(为了) space flights，可是后面接的是增加在社会福利，这样就不对了

请ｍｍ帮忙解惑，谢谢！！
