The abolition of slavery actually reduced the demand for cheap labor, as it meant that colonial powers could no longer rely on enslaved people to work their plantations and mines.

All of the industries listed were heavily reliant on cheap labor during the colonial era. Mining required large numbers of workers to extract minerals from the earth, agriculture required large numbers of workers to plant and harvest crops, and manufacturing required large numbers of workers to operate machinery and assemble products.

All of the regions listed were major sources of cheap labor for colonial powers. Africa was a major source of labor for plantations and mines, Asia was a major source of labor for plantations and factories, and Latin America was a major source of labor for plantations and mines.

All of the methods listed were commonly used by colonial powers to obtain cheap labor. Forced labor involved the use of coercion or violence to compel people to work, indentured servitude involved people agreeing to work for a period of time in exchange for passage to a new country, and debt bondage involved people being forced to work to pay off a debt.

All of the consequences listed were a result of the desire for cheap labor during the colonial era. The exploitation of workers involved paying workers low wages and forcing them to work long hours in dangerous conditions, the displacement of indigenous peoples involved forcing them off their land to make way for plantations and mines, and the spread of disease involved the introduction of new diseases to colonized regions by European colonizers.
