Final answer:
The question refers to an English Literature context, but no specific instance is found in the provided extracts where Lily asks her father a question and receives a direct response. Additional context or the title of the literary work is necessary to accurately answer the question.
Step-by-step explanation:
The question, "What one question does Lily ask her father and what is his response?" reflects a dialogue that could be found within literature, and hence it pertains to the subject of English Literature.
Based on the extracts provided, no explicit instance where Lily directly asks her father a question and receives his response is found. Instead, we see multiple conversations and reflections involving parents and their children or individuals recalling past experiences with significant others.
These dialogues can commonly address themes of family dynamics, memory, societal expectations, and gender roles—significant themes in many literary pieces—opening discussions about how sons and daughters typically respond to parental treatment and parents' differential treatment towards sons and daughters.
However, without additional context about Lily's interaction with her father in a specific work of literature, we cannot accurately determine the question she asks and his response. For a complete analysis or direct quotes, please provide the title of the work or additional context surrounding the exchange between Lily and her father.
