Step-by-step explanation:
The statement that the notion of separate spheres and the Cult of Domesticity allowed the American middle class to distinguish themselves as separate from and superior to the working class is True.
The notion of separate spheres and the Cult of Domesticity emerged during the 19th century and emphasized gender roles and divisions in society. It idealized women as moral and nurturing figures confined to the domestic sphere, while men were seen as providers in the public sphere. This ideology was predominantly embraced by the middle class, allowing them to assert their social superiority over the working class.
