Answer

Brief Explanations:

A merry - go - round is a familiar object that spins continuously. By comparing galaxy clusters to merry - go - rounds, the author likely wants to convey the idea that galaxy clusters are constantly revolving. Option A focuses on speed which isn't the main point of the comparison. Option C about weight and position isn't related to the comparison. Option D about commonness isn't what the comparison implies.

Answer:

B. to show that galaxy clusters never stop revolving
