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 in the 19th century was marked by a shift from local and regional markets to a national economy, significant developments in transportation infrastructure like roads, canals, and railroads, and innovations in communication and technology. These changes led to an increase in the distribution of goods, the rise of factories and mass production, and the growth of new social classes including industrialists and factory workers.
