It could be said that apparent retrograde motion of planets was the straw that broke the geocentric model's back. select all of the following statements that are accurate it would have completely impossible to extend the ptolemaic model to accurately predict apparent retrograde motion. earth exhibits apparent retrograde motion as seen from mars. a heliocentric model easily reproduces appaernt retrograde motion as an inevitable consequence of the orbits of the planets, including earth. mercury exhibits apparent retrograde motion frequently because it is close to the sun and orbiting witha very short orbital period. all the planets exhibit apparent retrograde motion. mars, jupiter, and saturn are the only planets that exhibit apparent retrograde motion. even with very complex epicycles and off-center orbits, accurate predictions of the timing, location and duration of apparent retrograde motion events could not be made using geocentric models.
