Final answer:
The market revolution in the United States during the early 19th century is indeed true and brought significant economic and social changes, including industrial growth, transportation and technology advances, and shifts in societal structures.
Step-by-step explanation:
The statement 'The market revolution brought many social and economic changes to the United States' is true. The market revolution, which occurred in the United States during the early 19th century, is characterized by a shift from a subsistence economy to a more commercialized, market-oriented economy. This profound transformation involved the rapid development and growth of industries, the expansion of transportation networks like canals and railroads, and the emergence of new technologies. These changes significantly altered the social fabric of the nation, leading to a more urban society, changes in labor patterns and family structures, and the growth of a consumer culture.
