Does your question have any options.If it does may you please tell me?
In colonial America, Africans "contributed" to society by being a source of income for people who bought and sold them into slavery. They also contributed by being laborers in the southern plantations.
Women contributed to the society by being a house wives --meaning they took care of the house-- as well as cooking meals for the family and taking care of the children.
Native Americans, in the earlier days, contributed by trading with settlers and teaching them how to do things in their environment.
