In this excerpt from F. Scott Fitzgerald’s “Bernice Bobs Her Hair,” which sentence reveals information about the setting of the story?

When Marjorie and Bernice reached home at half after midnight they said good night at the top of the stairs. Though cousins, they were not intimates. As a matter of fact Marjorie had no female intimates—she considered girls stupid. Bernice on the contrary all through this parent-arranged visit had rather longed to exchange those confidences flavored with giggles and tears that she considered an indispensable factor in all feminine intercourse. But in this respect she found Marjorie rather cold; felt somehow the same difficulty in talking to her that she had in talking to men. Marjorie never giggled, was never frightened, seldom embarrassed, and in fact had very few of the qualities which Bernice considered appropriately and blessedly feminine. Bernice felt a vague pain that she was not at present engaged in being popular. She did not know that had it not been for Marjorie's campaigning she would have danced the entire evening with one man.
