例5. A test of the National Weather Service’s stormdetecting radar systems found that the 1957 system is

ten times more reliable than the new computerized system. Therefore the technology used in the new

radar system must be less sophisticated than the radar technology used in the 1957 system.

  The conclusion drawn above depends on which of the following questionable assumptions?

(A) The reliability of storm-detecting radar systems is determined by the frequency of breakdowns.

(B) The level of sophistication of the technology used in storm-detecting radar system can be

determined from the reliability of the system.

(C) The reliability of storm-detecting radar systems is determined by their accuracy in predicting

weather patterns.

(D) Computer hardware is now a key component of the new storm-detecting radar systems used by

weather forecasting services.

(E) Most of the significant advances in stormdetecting technology were made in the 1950s.
