Final answer:
Customers value good manners, which is A) true, and the use of gift-giving ceremonies between empires historically demonstrated goodwill. The notion of separate spheres and the Cult of Domesticity did create a perceived superiority of the middle class over the working class.
Step-by-step explanation:
The question outlines two scenarios that reflect different aspects of social interactions and historical practices. Firstly, customers appreciate good manners and courtesy is a general notion that holds true across various contexts, including business and interpersonal relationships. Manners and courtesy are universally acknowledged as beneficial, fostering positive customer experiences and building lasting relations, which supports that the correct answer is A) True. Secondly, with regard to gift-giving ceremonies carried out between empires by their ambassadors, these practices were a way to demonstrate goodwill and establish diplomatic relations. Such exchanges were common in historical contexts to symbolize peace and cooperation between different nations or empires, hence the correct answer to this part of the question would be a. goodwill. In the case of the notion of separate spheres and the Cult of Domesticity, this was an ideology prevalent in 19th-century society that suggested women's place was in the home, fostering a domestic lifestyle that was seen as virtuous and pure. This idea indeed allowed the American middle class to create social distinctions between themselves and the working class, projecting a sense of superiority. Therefore, the correct answer here would be A) True.
