Answer 1

The correct contrast between the Proterozoic and Phanerozoic Eons is:

Proterozoic eon animals did not exist, and the Earth had only the Pangaea supercontinent. Phanerozoic eon animals began when dinosaurs developed, Earth had formed continents, and continental drift was beginning to happen.

This accurately reflects the timeline and characteristics of life and geological formations during these two eons. The Proterozoic mostly featured simple, single-celled organisms, while the Phanerozoic saw the emergence of complex multicellular life, including dinosaurs and other advanced organisms as continents shifted and formed.
