Final answer:
It is true that stride pianists often found work at rent parties. Sharecroppers were tenant farmers who paid their rent with shares of their crops, and the market revolution brought numerous social and economic changes to the United States.
Step-by-step explanation:
It is true that many stride pianists found work at rent parties. Rent parties were a social phenomenon primarily during the Harlem Renaissance where tenants hired musicians to play in their private homes to entertain guests who would then contribute to the rent of the host. Stride pianists, known for their flamboyant and interactive style, were in high demand at these events due to their ability to energize an entire room and keep party guests entertained.
Sharecroppers were indeed tenant farmers who paid their rent with shares of their crops. This system was prevalent after the Civil War, particularly in the Southern United States, and it often resulted in a cycle of debt and poverty for the sharecropper.
The market revolution significantly transformed many aspects of social and economic life in the United States, marking a shift from a subsistence economy to a more commercial and industrial one. This included the growth of factories, changes in transportation, and a shift in how goods were produced and consumed.
