Question

in what way did the roaring twenties signal a change in american social values?
it saw a decline in consumer culture.
it reinforced conservative values across the country.
it emphasized isolationism in culture.
it promoted a clash between traditional and modern values, particularly in urban areas.

Explanation:

The Roaring Twenties was a period of significant social change. Consumer culture actually thrived during this time (so the first option is incorrect). It was not a time of reinforcing conservative values uniformly (second option wrong). Isolationism in culture was not a key aspect (third option incorrect). However, there was a clash between traditional values (e.g., in more rural, conservative areas) and modern values (e.g., in urban areas with new forms of entertainment, changing gender roles with flappers, etc.).

Answer:

It promoted a clash between traditional and modern values, particularly in urban areas.
