The revolution in art has not lost its steam; it _ on as fiercely as ever.

Explanation

The correct answer is Rages because it conveys the idea of something continuing with intensity and force, which matches the depiction of the art revolution in the sentence. The other options-Trudges, Meanders, and Ambles-do not capture the intensity or the fierce, ongoing nature of the revolution in art. These words imply slowness or a lack of direction, which is contrary to the sentence's emphasis on intensity and persistence.
