Final answer:
The Buchanans are people of exquisite taste and refinement, but their image of luxury is unstable.
Step-by-step explanation:
The inference that can be made about the Buchanans based on the excerpt from Fitzgerald's The Great Gatsby is that they are people of exquisite taste and refinement, whose image of luxury and elegance is unstable like the wind blowing through the room. The description of the windows ajar, the gleaming white curtains, and the breeze blowing through the room suggest a sense of fragility and transience in their display of wealth and sophistication.
