Final answer:
To accurately answer what Mr. Andrews showed George and Phoebe, we need clarification on the specific literary work being referenced, as the details provided are from multiple sources with characters of similar names.
Step-by-step explanation:
The question relates to specific events in a literary work, which requires an understanding of the context within the story.
To answer what Mr. Andrews showed George and Phoebe, we must delve into the text itself.
However, the references provided span multiple pieces of literature and artwork, such as the painting Mr. and Mrs. Andrews (3.3.18) by Gainsborough and various narrative excerpts, which seem to involve characters named George, Phoebe, and Georgiana in different scenarios.
Without a clear indication of which specific work the question refers to, it's impossible to provide a factual answer.
Therefore, the correct approach is to seek additional clarification on the text in question before attempting to respond.
