Answer 1

The correct statement about Aristotle's and Ptolemy's models of the solar system is:

Ptolemy's model involved epicycles moving along perfect circles.

Ptolemy's geocentric model included the use of epicycles (small circular orbits) to explain the apparent retrograde motion of planets, with the planets moving in circles around points on larger circles (deferents). Aristotle's model did not incorporate epicycles but instead proposed a series of concentric crystalline spheres. Additionally, Aristotle's model also placed the Earth at the center, not the Sun.
