So the question is asking how the person thats telling the story use the story to explain facts about the natural world or specific Cherokee traditions. its sort like using the creation of the story as an example
The storyteller uses the creation myths to explains observable facts such as the mountainous nature of the Cherokee country, the seasons, sunrise and sunset, and the human reproductive cycle. The storyteller also relates specific information about Cherokee traditions and beliefs. For instance, the story discusses how the sun scorched the shell and spoiled the meat of the red crawfish, which helps explain why the Cherokee people don't eat the red crawfish.
