问题 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?
选项 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 C
解析 根据短文，卫星事故导致保险索赔大量增加，依次地，提高了保险费。更高的保险费使得卫星更昂贵，导致对卫星工作能力增加的需求。如果(C)是正确的，对工作能力的更大需求会通过增加事故的次数导致成本的进一步上升，因此推动保险费进一步上升，因此，(C)是正确答案；选项(A)、(D)和(E)都描述了与成本相关的因素，但没有理由相信，短文中所描述的情形会导致由这些因素引起的成本上升；相似地，不可能有指出它无法工作的原因，如(B)提到的，与卫星成本维持稳定没有矛盾。
