Here’s how to categorize the items based on their relation to Aristotle’s and Ptolemy’s models of the solar system:
Aristotle's Model:
- Planets fixed on nested spheres
- Geocentric
Ptolemy's Model:
- Planets fixed on epicycles
- Accurately predicted the positions of the planets
Both Models:
- Geocentric (Both Aristotle and Ptolemy's models are geocentric, meaning they both placed the Earth at the center of the universe.)
So, "Geocentric" can be placed under both Aristotle and Ptolemy. All other items are specific to their respective models.
