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, which occurred in the United States during the first half of the 19th century, drastically changed the economy from one that was predominantly agrarian and artisan-based to one that was increasingly centered around industrial manufacturing and commercial activity. This transformation led to the emergence of a more integrated national economy, stimulated the growth of cities, and contributed to significant shifts in social and labor patterns, including the expansion of the factory system and the rise of a distinct working class.
