Final answer:
The political cartoon of the early 1920s most likely symbolizes 'Prohibition', the period when the sale, production, and transportation of alcoholic beverages were outlawed in the United States, which led to widespread illegal activity and an underground alcohol culture.
Step-by-step explanation:
The event of the early 1920s that the political cartoon likely symbolizes is a) "Prohibition". The early 1920s was marked by the introduction of Prohibition, which was the ban on the sale, production, and transportation of alcoholic beverages in the United States. This era saw the rise of illicit activities, including bootlegging and speakeasies, as Americans sought ways to circumvent the law. While Prohibition was meant to enforce sobriety and reduce crime, it paradoxically led to a booming underground culture of alcohol consumption and organized crime.
The Depression or the Stock Market Crash, which led to the Great Depression, occurred at the end of the 1920s, specifically in 1929, so these are not represented by a political cartoon of the early 1920s. The Harlem Renaissance, also a significant movement of the 1920s, celebrated African American culture, music, and arts but is also an unlikely subject for a political cartoon specifically addressing a legislative event like Prohibition.
