Question

1. which model of the universe was theorized by the ancient greeks?

the lunar - centric model
the geocentric model

Explanation:

The ancient Greeks, particularly Ptolemy, developed the geocentric model, which places Earth at the center of the universe. While Aristarchus proposed a heliocentric (solar-centric) model, it was not widely accepted in ancient Greek thought; the dominant model was geocentric. Lunar-centric models are not associated with ancient Greek cosmology.

Answer:

the geocentric model
