The best response that describes how push and pull factors impacted Native Americans during the early 1800s is:
Push factors like increasing pressure from European settlers and government policies forced Native Americans to leave their ancestral lands.
During this period, many Native American tribes were forcibly removed from their lands due to the expansion of European settlers and the implementation of government policies such as the Indian Removal Act of 1830. This overwhelming pressure, alongside factors like the encroachment of settlers and the demand for land for agriculture and settlement, significantly contributed to the displacement and relocation of Native American tribes from their traditional territories.
