[求助]OG-32还没解决的疑惑

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.

og对选项B的解释是,the impossibility of pinpointing the cause of failure, mentioned in B, is consistent with the cost of satellites remaning stable!

我的问题是:为什么the impossibility of pinpointing the cause of failureis consistent with the cost of satellites remaning stable,两者到底是什么关系, 怎么会stable??

thanks for your attention and patience!!

我的理解是，就是因為impossible to pinpoint the cause of the failure

所以保險成本也不該上漲，當然與原題不合，所以不選

真得很感谢,只有你理我.谢谢

the question asked 'if true, taken together with the information above..."

B-- the failure or reaching orbit were not mentioned in the passage.., therefore, "the impossibility of pinpointing the cause of failure "
