Answer 1

The three correct answers that provide evidence that South America, Africa, Antarctica, and Australia were once together as one supercontinent are:

1. Fossils of marsupials were originally the same across South America and Australia.
2. Glacial deposits and scratches in the bedrock from an ice sheet match in distant regions.
3. Mountain chains match up where South America collided with Australia to form Pangaea.

These pieces of evidence support the idea of continental drift and the existence of Pangaea, where continents that are now separated were once joined together.
