Question

Question 25 Why does the author compare galaxy clusters to "merry-go-rounds" in paragraph 4? A. to show how quickly galaxies rotate in space B. to show that galaxy clusters never stop revolving C. to show how weight and position affect revolution speed D. to show how common rotating galaxy clusters are in space

Answer 1

The correct answer is C. to show how weight and position affect revolution speed. The comparison to "merry-go-rounds" typically illustrates how different factors, such as mass and distance from the center, can influence the speed at which objects (like galaxies in a cluster) revolve around a central point.
