The correct answer to this open question is the following.
Identify the characteristics of each system that Europeans established in the Americas.
1.- The Encomienda System.
The Spanish colonists were the ones who introduced the Encomienda system in their territories in America. In this form of "slavery system," landowners made the Native Indians work their lands in exchange for housing, clothes, and food. Religious Congregations focused on evangelizing the Catholic religion to the Native American Indians.
2.- The Headright System.
The English colonists were the ones that introduced this system in the North American territory. Tobacco plantation owners paid for the voyages of workers that came from Europe to work in the farmlands of America. They hired indentured servants because they were much needed to grow crops that had to be exported to Europe.
