Final answer:
The statement is true; the market revolution of the 19th century indeed brought significant social and economic changes in the form of a market-based economy, technological advancements, and new social classes in the United States.
Step-by-step explanation:
The statement that the market revolution brought many social and economic changes to the United States is true. The market revolution, which took place in America during the 19th century, significantly altered the economy by transforming the production and distribution of goods. Innovations in transportation, such as canals and railroads, along with technological advances like the cotton gin and telegraph, facilitated the swift movement of goods and information.
This led to the growth of a market-based economy, an increase in the number of factories, and created new social classes including a distinct industrial working class and a wealthy industrial capitalist class. The impact of the market revolution also extended to agriculture, as farmers began to produce crops for sale rather than just for subsistence.
