Final answer:
Sharecroppers indeed paid their rent with a portion of their crops, and the market revolution did result in numerous social and economic changes in the United States; both statements are true.
Step-by-step explanation:
The question you've asked pertains to historical events and periods. Specifically, it revolves around two significant aspects: sharecropping and the market revolution. Firstly, the statement that sharecroppers were tenant farmers who paid their rent with shares of their crops is true. Sharecropping was a system that emerged during the Reconstruction era in the Southern United States, where freed slaves and poor white farmers rented land from landowners and paid for the use of the land with a portion of the crops they harvested.Regarding the market revolution, the statement that it brought many social and economic changes to the United States is also true. The market revolution was a period in the early 19th century marked by a significant increase in the exchange of goods and services, developments in infrastructure and transportation, the growth of cities, changes in labor, and the start of factory systems. These changes had a profound impact on the economic and social structure of America.
