16.   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.（C）

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

先理解题目：电视卫星的大量损坏使得保险费上涨，保险费的上涨又使得卫星运营成本增加，因此电视公司更多利用现有卫星，使其担负更多内容。问：哪个答案结合题目可以得出卫星成本会持续上涨的结论？

看起来这道题目是加强题，其实一定程度上也是道归纳题，既然问题要求你“结合文章内容”，则答案必然与文章有关。文章中提到，导致成本上升的原因是保险费的上涨，则答案必然也和保险费有关。看C，卫星被利用的越多，损坏的可能越大。损坏了就要赔偿，保险费就必然进一步上涨－－符合了原文的推理过程。

其他答案：A说保险费很高，没有说increase，这是一个混淆。B失败原因、D规模经济、E效率低下都与原文推理无关。
