After observing the Earthâ€™s weather patterns and the 11-year sunspot cycle of the Sun for 36 years, scientists have found that high levels of sunspot activity precede shifts in wind patterns that affect the Earthâ€™s weather. One can conclude that meteorologists will be able to improve their weather forecasts based on this information.
Which of the following, if true, most seriously weakens the argument above?
(A) Weather forecasts are more detailed today than they were 36 years ago.
(B) Scientists can establish that sunspot activity directly affects the Earthâ€™s weather.
(C) Evidence other than sunspot activity has previously enabled meteorologists to forecast the weather conditions that are predictable on the basis of sunspot activity.
(D) Scientists have not determined why the sunspot activity on the Sun follows an 11-year cycle.
(E) It has been established that predictable wind patterns yield predictable weather patterns.
