Final answer:
The United States government confined most western tribes to reservations to end conflict between American Indians and colonists.
Step-by-step explanation:
The correct answer is It confined most western tribes to reservations. In an effort to end conflict between American Indians and colonists, the United States government implemented policies that forced many Native American tribes onto reservations. Reservations were designated areas of land where tribes were expected to live and conduct their affairs. This policy aimed to separate Native Americans from colonists and reduce the potential for conflict and violence. By confining tribes to reservations, the government believed it could exert more control over interactions and avoid clashes between settlers and indigenous populations.
