Question

what helped manufacturers keep up with consumers in the 1920s?
○ fewer regulations and lower taxes
○ more regulations and lower taxes
○ changing demands of buyers
○ aggressive advertising campaigns

Explanation:

In the 1920s, a key development that allowed manufacturers to match consumer demand was the use of aggressive advertising campaigns. These campaigns created and fueled consumer desire, expanded markets, and helped manufacturers sell the increased output from mass production. Fewer regulations/lower taxes did not directly enable keeping up with consumers, more regulations would hinder production, and changing buyer demands were a challenge to address, not a solution.

Answer:

D. aggressive advertising campaigns
