Question

• was the 1920s truly \prosperous\ for everyone?
• did prohibition cause more problems than it solved?

Explanation:

These questions relate to the history and social context of the 1920s in the US. The subfield of History (under Social Science) deals with analyzing historical periods, events like Prohibition, and the socioeconomic conditions of different groups during the 1920s. By examining historical records, economic data, and social experiences of various demographics (e.g., working - class, minorities, rural vs. urban populations) for the first question, and the impact of Prohibition on crime, social norms, and the economy for the second, History is the appropriate subfield.

Answer:

The subfield that best applies to these questions is History (under Social Science).
