Final answer:
The assertion that the market revolution brought significant social and economic changes to the United States is true. It marked a time of industrialization and commercialization with substantial impacts on the social fabric and economic aspects of the country.
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 refers to the period, particularly in the early to mid-19th century, during which the United States transformed from a disaggregated, subsistence economy to a more commercialized and industrial one. This transformation was driven by various innovations such as the steam engine, which facilitated faster transportation, as well as technological advancements in communication such as the telegraph.
This period saw significant changes in the way goods were produced and consumed, leading to shifts in social dynamics and the growth of cities as centers of manufacturing and commerce. There were also dramatic changes in labor, with more people working in factories rather than on farms, and the emergence of new classes, such as the industrial capitalist and the wage laborer.
