Which describes one way that Aristarchus's explanation of the movement of objects in the sky was different from other scientists' earlier explanations?

Aristarchus proposed that Earth spins on its axis and moves around the Sun, unlike earlier explanations that treated Earth as stationary. This makes “He argued that Earth rotates on its axis” the correct choice. Venus’s phases were discovered much later, and epicycles were part of a different model used to explain planetary motion.
