Final answer:
The ”roar” of the Roaring Twenties refers to the period's economic prosperity, cultural blossoming, and entertainment boom, especially in jazz music, which was coupled with a shift in societal norms and consumerism.
Step-by-step explanation:
The ”roar” of the Roaring Twenties most likely refers to the period of economic prosperity, cultural dynamism, and the booming of entertainment such as jazz music. This decade is characterized by several factors, including technological innovations, the rise of popular entertainment like movies and radio, and a shift towards modern values and increased consumerism.
During the 1920s, America went through a significant transition with societal norms shifting drastically. The era saw the emergence of “flappers,” who symbolized women with new levels of social and personal freedom, as well as bootlegging and speakeasies, which arose in response to Prohibition. The decade also witnessed a remarkable growth in the arts, exemplified by the Harlem Renaissance. Unfortunately, the excesses of the 1920s led to the Great Depression, thus bringing an end to a decade of high spirits and optimism.
