Answer:
1. Spanish and Portuguese officials who resided temporarily in Latin America: They were considered as "peninsulares", and encompassed the high bureaucracy in the colonies (from the viceroy, to the high military posts)
2. area dominated by Portugal form the sixteenth century forward: Brazil
3. offspring of Europeans and Native Americans: They were called "Mestizos".
4. allowed Spanish authorities to draft native workers to work in silver mines: There were two forms of draft, one in the Viceroyalty of New Spain (Mexico) which was the encomienda, and the other in the Viceroyalty of Peru that was called "mita". Both were essentially the same, allowing the use of native labor, but the "mita" also had the specificallity of being a native method of drafting, inherited from the Inca Empire.
5. descendants of Europeans born in Latin America: They were called "Criollos" (Creoles). They could own lands and encomiendas, but could not aspire to higher bureaucracy posts, with the position of Mayor being the highest honor they could aspire in the bureaucracy.
