The correct answer is D) a greater variety of goods for fair prices.
Manufacturers during the 1920's used advertisements in order to increase consumerism within the United States. These advertisements were successful because companies were now producing more goods for lower prices. This reduction in price can be contributed to inventions like the assembly line, which dramatically decreased the cost of producing goods. This reduced cost in making goods allowed for businesses to offer goods for a lower price. These lower prices made citizens more likely to buy these goods.
