If Earth

If Earths orbit were a perfect circle, we would
not have seasons.

1. True, because it is the departures from a
   circular orbit that create the seasons on Earth.
   
2. False the seasons are due to the tilt of the
   Earths spin from its orbit, not its distance
   from the Sun.
3. True the Earth would be at the same distance
   from the Sun throughout its orbit, so there would
   be no summer or winter.
4. False the poles would still be cooler than the
   equator and seasonal variations would therefore
   still exist.

Mars occasionally undergoes retrograde motion,
which is

1. When Mars rises towards the West and sets towards
   the East --- the opposite of what the Sun and
   stars do
2. When Mars position on the sky from night to
   night moves from the West towards the East
3. Neither of the above
