Final answer:
Symphonies, art museums, and classic literature were preferred by the urban elite to demonstrate their refined taste and cultural knowledge, offering an alternative to the popular entertainment of the working class.
Step-by-step explanation:
What do the symphony, art museums, and classic literature have in common? These cultural entities serve as hallmarks of refined taste and sophistication, often associated with the social and cultural practices of the urban elite. During a period when wealthy citizens were distancing themselves from the entertainment of the working class, symphonies, art museums, and classic literature provided a sanctuary that underscored their knowledge of art and culture. Venues like Carnegie Hall and the Metropolitan Museum of Art became central to this elevated cultural experience. The symphony, a complex form of classical music, together with the collections of fine art and the revered works of classic literature, formed an integral part of the social life of the upper class, a world away from the more populist entertainments like amusement parks and baseball games.
