Final answer:
Native Americans who joined Spanish missions could receive benefits like steady food supply, protection, and gifts, but also faced exploitation. Some found jobs or sincerely adopted Christianity.
Step-by-step explanation:
The benefits for Native Americans joining the Spanish mission were multifaceted. By aligning themselves with the Spanish, Native Americans could receive steady food supply and protection from their enemies, which were significant incentives to participate in the mission life.
While the Spanish also promised the gifts of Catholicism and the potential for economic opportunities, the reality often involved significant exploitation and imposition of foreign belief systems. Nevertheless, some Native Americans found advantages in cooperation, such as positions in colonial administrations, or as interpreters, soldiers, or police. Others converted to Christianity and sincerely embraced the new faith.
