A

Difficulty: Medium

Category: Development: Relevance

Getting to the Answer: Reread the paragraph to understand the author's claims. Which answer choice provides a fact that would best support these claims? Make sure the answer choice does not digress from the progression of ideas. The speed of the solar flare is referenced as being three times the speed of normal solar winds, but neither exact speed is given. To make a stronger case for the author's statements, both speeds should be stated. Therefore, (A) is the correct answer.
