what helped manufacturers keep up with consumers in the 1920s?\n○ fewer regulations and lower taxes\n○ more regulations and lower taxes\n○ changing demands of buyers\n○ aggressive advertising campaigns
Answer
Brief Explanations:
In the 1920s, aggressive advertising campaigns were a key strategy for manufacturers to keep up with consumers. Fewer regulations and lower taxes or more regulations and lower taxes mainly affected the business - operating environment rather than directly helping to keep up with consumers. The changing demands of buyers were something manufacturers needed to respond to, but advertising was a tool to reach and influence consumers. Aggressive advertising campaigns could create awareness, generate demand, and promote products to match or even drive consumer preferences.
Answer:
aggressive advertising campaigns
