a find the size of the universe.
b interpret astrological signs and myths.
c predict tsunamis and volcanic eruptions.
d explain observations of the stars, the moon, and the sun

Explanation:

Both the geocentric and heliocentric models were developed by astronomers to make sense of the observed motions and positions of celestial bodies like stars, the Moon, and the Sun. Option A is incorrect because neither model was used to find the universe's size. Option B is wrong as these are scientific astronomical models, not tools for astrology. Option C is unrelated, as the models have no connection to predicting geological events like tsunamis or eruptions.

D. explain observations of the stars, the Moon, and the Sun
