标题: 请教OG10-32

32. 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, has 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.

答案是C，请问怎么推出来的？

从原文我们看出，发射新得卫星费用上升（因为。。。），所以有人提出一个做法，就是让现有卫星做更多工作（来解决费用上升问题）

C指出卫星做得工作越多，越容易损坏。结论就是越需要发射新得卫星。总之，费用上升
