Answer 1

The correct statement is:

**Ptolemy's model involved epicycles moving along perfect circles.**

Ptolemy developed a geocentric model of the universe which used epicycles (small circles) on which planets moved, with the centers of these circles moving along larger circles (deferents), all while maintaining the idea that the planets moved in circular orbits, since circles were considered perfect shapes.
