Final answer:
True, the notion of separate spheres and the Cult of Domesticity allowed the American middle class to distinguish and elevate themselves above the working class by adhering to societal norms that enforced gender-defined domains and moral values.
Step-by-step explanation:
The statement, "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 concept of separate spheres divided the world into a public domain where men were expected to work and engage in politics, and a private, domestic domain that was seen as the proper realm for women. The Cult of Domesticity was an ideology that promoted the idea that women should embody perfect virtue in all senses and stay at home as dutiful mothers and wives. These societal norms allowed the middle class to set themselves apart, expressing their social status and moral superiority.
