At the beginning of paragraph 9, Madame Valmonde exclaims, “This is not the baby!” What causes her to make this proclamation?

Madame Valmonde responds to the color of the child's skin..... a response to the fact that the infant undoubtably has African heritage.

Madame Valmondé had never removed her eyes from the child. She lifted it and walked with it over to the window that was lightest. She scanned the baby narrowly, then looked as searchingly at Zandrine, whose face was turned to gaze across the fields.
