The three correct answers that provide evidence that South America, Africa, Antarctica, and Australia were once together as one supercontinent are:
1. **Glacial deposits and scratches in the bedrock from an ice sheet match in distant regions.**
This evidence suggests that continents were once connected and shared a common climate.
2. **Fossils of marsupials were originally the same across South America and Australia.**
The presence of similar fossil species on different continents indicates they were once joined.
3. **Cratons match across the edges of continents.**
The alignment of ancient geological formations supports the idea that these continents were once part of a larger landmass.
These pieces of evidence are commonly cited in discussions of plate tectonics and the theory of continental drift, particularly in reference to the supercontinent Pangaea.
