Question

after the civil war, many freed slaves became...
sharecroppers.
industrial workers.
day laborers.
union workers.

Explanation:

After the American Civil War, many freed slaves, due to economic and social circumstances (like lack of land ownership, limited industrial job opportunities in the South initially, and the prevalence of the sharecropping system in the agricultural South), became sharecroppers. Sharecropping was a system where landowners provided land, tools, and seed in exchange for a share of the crop, and it was a common path for freed slaves who needed to work but had few other options. Industrial work, day laborer roles (in a more generalized sense not as prevalent as sharecropping for this demographic post - Civil War), and union work (unions were not as accessible or common for freed slaves immediately post - war) were not the dominant outcomes.

Answer:

A. sharecroppers
