Passage Summary: While some think folktales are just for fun, the fact that they are shaped by many people over a long time means they actually reveal the deep wisdom of a culture.

Conclusion: Folktales offer significant understanding of a culture's collective wisdom.

Reasoning: Folktales are traditional stories passed through generations where each storyteller contributes their own elements to the narrative.

Analysis: The argument assumes that the process of multiple generations adding to a story automatically results in a product that reflects cultural wisdom. To bridge this gap, we need a 'Sufficient Assumption' that guarantees this outcome. Look for an answer that explicitly links the act of many storytellers adding to a traditional story with the inevitable creation of cultural insight.
