Answer 1

The two correct answers regarding which statements about the geocentric model are false are:

1. It shows the Sun at the center of the solar system.
   (This statement is false because the geocentric model places Earth at the center, not the Sun.)

2. It explains why Mars appears to move backward for a few months approximately every two years.
   (This statement is also false, as the geocentric model does not adequately explain the retrograde motion of Mars; that explanation comes from the heliocentric model.)

The other statements are true in the context of the geocentric model.
