Step-by-step explanation:
The ancient goal of astrology was B) predict human events. Astrology is often considered a natural science in its historical context, as it involves observations and predictions of events in the sky and their supposed influence on human affairs and the natural world. Ancient cultures integrated astrology into their understanding of the universe, attributing changes and events they observed in their daily lives to the movements and positions of celestial bodies. Astrology reached its peak during the Greco-Roman period, epitomized by the work of Ptolemy in his Tetrabiblos. Ptolemy's mathematical and cosmological model, which was based on a geocentric view of the universe, was used to predict the positions of the planets and became authoritative for over a millennium. Though modern evidence disproves astrology's predictive power over personal destinies, its historical role in motivating interest in celestial phenomena is undeniable.
