Question

which of these events first allowed many more settlers to move west?
○ the completion of the transcontinental railroad.
○ the passing of the indian appropriations act.
○ the defeat of american indians at the battle at wounded knee.
○ the institution of the reservation system.

Explanation:

The completion of the trans - continental railroad made it easier and faster for settlers to move west. It opened up new areas for settlement by providing a means of transportation for people, goods, and resources. The other events (defeat at Wounded Knee, Indian Appropriations Act, and reservation system) were more related to the subjugation and control of Native Americans rather than directly enabling more settlers to move west.

Answer:

the completion of the transcontinental railroad
