Answer:
The idea the author develops with the text example cited in the excerpt is that the Grimms found stories that express real-life situations. This is evident based on the fact that the tales the brothers collected were largely oral stories told by those living in rural villages, and these tales frequently depicted the harsh realities of life such as poverty, illness, death, and exploitation. The accounts were also often quite dark and reflected the difficult circumstances of everyday life. Therefore, it can be concluded that the Grimms found stories that express real-life situations, although they may have embellished some details or changed parts of the stories to be less dark for the final edition.
