请教OG11-33 （紫皮，没人问过）

33．  A recent spate of launching and operating mishaps with television satellites led to a corresponding surge in claims against companies underwriting satellite insurance．As a result, insurance premiums shot up，making satellites more expensive to launch and operate．This，in turn，had added to the pressure to squeeze more performance out of currently operating satellites．

Which of the following, if true, taken together with the information above，best supports the conclusion that the cost of television satellites will continue to increase?

(A)  Since the risk to insurers of satellites is spread over relatively few units，insurance premiums are necessarily very high．

(B)  When satellites reach orbit and then fail，the causes of failure are generally impossible to pinpoint with confidence．

(C)  The greater the performance demands placed on satellites，the more frequently those satellites break down．

(D)  Most satellites are produced in such small numbers that no economies of scale can be realized．

(E)  Since many satellites are built by unwieldy international consortia，inefficiencies are inevitable．

Argument Evaluation

Situation  A rise in the number of claims after a series of accidents has forced insurance companies to raise prices for coverage of television satellites．Consequently, new satellites are more expensive，and existing satellites must perform more．The cost of television satellites will continue to increase．

The correct answer is C．

这里从原文实在推导不出来and existing satellites must perform more， 

是不是因为卫星老是出事，所以它必须perform more呢？但是前面说了This，in turn，had added to the pressure to squeeze more performance out of currently operating satellites． 是使它性能越来越 差啊。

谢谢！

自己顶一下

As a result, insurance premiums shot up，making satellites more expensive to launch and operate．This，in turn，had added to the pressure to squeeze more performance out of currently operating satellites．

保险费用升高，使得卫星发射和运行的成本越来越高。反过来，不得不精简现有的卫星的功能。  

我这样解释对吗？

我的疑惑是因为有In turn(成本越来越高），所以有pressure来减少（squeeze out）现在卫星的performance。

这句话是看了好久都没看懂。

不是,理解错了.意思是说近来发射卫星屡次的问题(mishap)造成了要求承诺支付保险 因为保险费涨,所以造成运营费用越来越高.那么反过来,公司肯定会缩减卫星数量,让现有卫星做更多工作(不然成本不是狂涨).

到这里为止,你会发现成本可能是不会增加的,但题目却要你证实成本增加这个结论

要填补这个gap只有选C.你让卫星做更多工作,那就更容易坏,更容易坏,保险支付就越多.为了控制越多的保险费(与卫星数量相关),就让卫星做更多工作.....

这样就陷入了一个vicious cycle,这个cycle的唯一结果就是成本永远会增加
