Final answer:
The statement is true; the market revolution significantly transformed the social and economic landscape of the United States in the 19th century by industrializing the economy and altering social dynamics.
Step-by-step explanation:
The statement that the market revolution brought many social and economic changes to the United States is True. This period, which occurred in the early to mid-19th century, was characterized by a dramatic change in how goods were produced and consumed. Innovations such as the cotton gin, the expansion of the railroad network, and the use of factory systems changed the American economy from one based on individual and local production to a more national, industrialized system.
These changes spurred significant social shifts, including urbanization, as people moved to cities in search of factory work, and transformations in family structures and gender roles, with more people working outside the home. Additionally, this revolution widened the gap between the wealthy and the poor, as it gave rise to a new class of industrialists and a large working class.
