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.

c当然是对的，但是a不是更直接吗——premium高了，cost当然相应的就高了。请指教
