Final answer:
The provided excerpts do not include a statement by Margaret about Beatrice, thus an accurate response to what Margaret says Beatrice is stuffed with cannot be given.
Step-by-step explanation:
In the provided excerpts, the specific phrase regarding what Margaret says Beatrice is stuffed with is not given. Therefore, based on the excerpts, it is impossible to determine exactly what Margaret says about what Beatrice is stuffed with. The excerpts do provide various dialogues and descriptions from different characters interacting and expressing themselves, but none contain a direct reference to Margaret speaking about Beatrice being stuffed with anything. The references to different characters and their dialogues or descriptions signify the literary and narrative aspects of the texts, suggesting the subjects are drawn from works of fiction or drama. Since the exact phrase cannot be found in the excerpts, an accurate answer to the student's question cannot be provided.
