Hello there! I'm happy to help you!
Let's begin by reading the definition of the term 'divide' within this context, which according to the dictionary is the following:
<h3>Divide:</h3>
- <em>'A divide is the elevated boundary between areas that are drained by different river systems.'</em>
The Great Divide is a 'continental divide', merely the most famous divide of the Americas. It runs from Alaska and extends to the tip of South America, crossing in it's way the Rocky Mountains, and Sierra Madre Occidental in Mexico.
In a continental divide, the drainage basin on one side feeds into one ocean or sea, and another sea or ocean feeds from another side of the drainage basin.
The correct answer is: They feed different water sheds.
Hope this helps! Have an excellent year! :)
