Answer:
b) To experience religious freedom and obtain more land and natural resources.
Step-by-step explanation:
The texts state that people in the East faced limited religious freedom and a lack of jobs, and that the promise of open land, new jobs, and religious freedom drew people further into the continent. Additionally, the new land in the West contained untapped resources such as forests, plains, and ore. Therefore, the United States wanted to move westward to obtain more land and natural resources, and to seek greater religious freedom and economic opportunities.
