After studying the Earth's climate changes and the 10-year cycle of solar flares for 30 years, researchers have discovered that increased solar flare activity often precedes changes in ocean currents that influence global climate. This suggests that climatologists could enhance their climate predictions using this data.
Which of the following, if true, most seriously undermines the argument above?
Answer Choices
Correct answer marked belowA
A) Climatologists have access to more advanced technology for climate modeling than they did 30 years ago.
B
B) Researchers can prove that solar flare activity has a direct impact on the Earth's climate.
C) Other factors besides solar flare activity have historically allowed climatologists to predict climate changes that are associated with solar flare activity.
Correct
D
D) Researchers have not yet figured out why solar flare activity follows a 10-year cycle.
E
E) It has been shown that changes in ocean currents lead to predictable climate variations.

The argument states that increased solar flare activity can help improve climate predictions. To weaken this argument, we need to show that there are other reliable methods for predicting climate changes that do not rely on solar flare activity. Option C states that other factors besides solar flare activity have historically…
