The diagram shows two models. Which statement accurately describes both models?

• Model X is the heliocentric model in which Earth is the center of the solar system; model Y is the geocentric model in which the Sun is the center of the solar system.

• Model X is the geocentric model in which the Sun is the center of the solar system; model Y is the heliocentric model in which Earth is the center of the solar system.

• Model X is the heliocentric model in which the Sun is the center of the solar system; model Y is the geocentric model in which Earth is the center of the solar system.

• Model X is the geocentric model in which Earth is the center of the solar system; model Y is the heliocentric model in which the Sun is the center of the solar system.

Which of the following best explains how Ptolemy’s and Copernicus’s models of the solar system differed?

• Ptolemy’s views of the solar system were rejected, but Copernicus’ views were widely accepted.

• Ptolemy did not have an explanation for why planets would seem to move backwards, but Copernicus did.

• Ptolemy believed in the geocentric solar system, while Copernicus believed in the heliocentric solar system.

• Ptolemy believed everything revolved around the Sun, while Copernicus believed everything revolved around the Earth.
