This question is about "A Matter of Prejudice".
Answer:
The description of the house shows how old and outdated it was, just like its owner Madame Carambeau.
Step-by-step explanation:
Madame Carambeau is a woman full of prejudices, old-fashioned, snobbish and intolerant. She lives within old concepts that no longer fit within today's society and this causes her to stop enjoying many good and happy things that life can offer, such as keeping a family together, having friends and keeping in touch with her own son. .
The old-fashioned way that Madame Carambeau lives can be seen even in her home, which has an outdated and somewhat old model by the standards where the story takes place.
