Step-by-step explanation:
When addressing the question of whether the market revolution brought many social and economic changes to the United States, the answer is True. The market revolution, which occurred in the early 19th century, transformed the American economy from one primarily based on subsistence farming to a more commercial and industrial system. This shift led to significant changes in various aspects of American life, including the way goods were produced and consumed, the rise of urbanization as people moved to cities to work in factories, and the development of a more interconnected national economy through improved transportation networks like canals and railroads.
