Explanation:
After the Civil War and 13th Amendment, slavery was abolished from the United States. This left 4 million former slaves or freedmen to fend for themselves while looking for jobs, homes, and educations during the period of Reconstruction.

The correct answer is: "the domestication of animals "
Although it was baptized by a change in the way of working the stone, the Neolithic is a complex phenomenon that marks the end of predation as a way of life and the beginnings of agriculture and livestock.
About 12,000 years ago, the way of life of the human beings that inhabited certain geographic zones began to transform radically. Predatory occupations, such as hunting and gathering, were replaced little by little by others of a productive nature, such as the domestication of animals and the cultivation of the land and, in this way, the societies of Homo sapiens gradually abandoned nomadism and subsistence economy to become sedentary and producers of their own food.
