Step-by-step explanation:
The excerpt from Fitzgerald's The Great Gatsby suggests that the Buchanans are people who strive for a luxurious and elegant lifestyle. The description of their house with its gleaming windows, fresh grass, and expensive decorations implies that they have spent a fortune to create an image of beauty and refinement. However, the image is also portrayed as unstable, symbolized by the breeze blowing through the room and the curtains twisting like flags. This suggests that there may be underlying issues or insecurity beneath their outward display of wealth and elegance.
