what is the source of this question?
C is right b/c of " previously".
I do not think this question belongs to one of official questions.

16. After observing the Earth’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 Earth’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 Earth’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.

IMO Option C is a right answer given that the last part of the sentence which states "on the basis of sunspot activity" is removed.
Essentially answer option C is ambiguous the reason being we cannot definitely ascertain whether the evidences are predictable basis the sunspot activity or the forecast is predictable basis the sunspot activity.

So kindly provide explanation to this.
