Final answer:
The statement is true; the market revolution significantly restructured the United States' social and economic fabric during the early 19th century, leading to urbanization, the emergence of a middle class, and increased sectional differences.
Step-by-step explanation:
The statement that the market revolution brought many social and economic changes to the United States is true. During the early 19th century, the market revolution was characterized by a shift from manual labor and artisanal, home-based work to mechanized industry and factory systems. This transformation was largely driven by technological innovations such as the steam engine, the cotton gin, and improvements in transportation like canals and railroads.
The market revolution significantly altered the economic landscape of America. It catalyzed the growth of cities, as people moved from rural areas to urban centers in search of work in factories. Socially, it led to the rise of a new middle class while simultaneously widening the gap between the wealthy elite and the working poor. Additionally, the market revolution played a role in intensifying regional differences, particularly between the industrial North and the agricultural South, which would later contribute to sectional tensions leading up to the Civil War.
