Final answer:
The excerpt suggests that the Buchanans are people of exquisite taste and refinement who project an image of luxury and elegance.
Step-by-step explanation:
The excerpt from Fitzgerald's The Great Gatsby suggests that the Buchanans are people of exquisite taste and refinement. The language used to describe their house, such as 'gleaming white' windows and a 'frosted wedding-cake' ceiling, evokes an image of luxury and elegance. Additionally, the open windows symbolize their openness to new people and ideas. Therefore, the correct inference is that the Buchanans are people who project an image of luxury and elegance.
