The details that develop the central idea that the Grimms collected stories to preserve culture include:
- The Grimm Brothers recorded the stories because fewer and fewer people were collecting and preserving them, reflecting their concern about the loss of oral traditions and cultural heritage
- The tales of the Grimm Brothers demonstrate how language and customs can create a bond between people, showing that the stories and their morals emanated naturally from the German people in an oral tradition and helped forge community bonds
- Their stories reveal truths about the conditions people lived in when the tales were recorded, as the tales reflect the difficult conditions and cultural values of the time
The detail about the Grimms being born in Germany in the 1700s and publishing in the 1800s is factual but does not directly develop the central idea of preserving culture. Similarly, the detail about their surprise at being known more for their tales than their literary studies does not directly support the preservation theme
. Thus, the key supporting details are those emphasizing the Grimms' intent to save disappearing oral traditions, the cultural bonding through language and customs, and the reflection of historical living conditions in their tales.
