The answer is continental drift.
Continental drift is the geological theory that explains how continents move through Earth's surface. All continents were once connected as one supercontinent Pangea. On that supercontinent, populations of one species lived together in one location. But after continents spread apart, these populations were separated on different continents. So, all marsupials lived on Pangea. After continental drift, some populations remained in Australia, and other remained in North America.
Choices:
Marsupials used to have adaptations that allowed them to swim but lost these adaptations over time.
The two groups of marsupials evolved independently of one another on two separate continents.
The continents were once connected, and marsupials were able to migrate over the land.
The oceans were shallow in prehistoric times, which allowed the marsupials to travel from one continent to another.
