Question refers to the excerpt below. "And every Indian born within the territorial limits of the United States to whom allotments shall have been made under the provisions of this act, or under any law or
treaty, and every indian bom within the territorial limits of the United States who has voluntarily taken up, within said limits, his residence separate and apart from any
tribe of Indians therein, and has adopted the habits of civilized life, is hereby declared to be a citizen of the United States, and is entitled to all the rights, privileges, and
immunities of such citizens, whether said Indian has been or not, by birth or otherwise, a member of any tribe of Indians within the territorial limits of the United States
without in any manner affecting the right of any such Indian to tribal or other property."-From the Dawes Act, 1887

How does the policy described in this excerpt reflect a change in U. S. federal law?

Reservations would be disbanded in favor of incorporating native peoples into existing white communities throughout the country

Assimilation into white culture was now the official recommended policy instead of the segregation of the reservation system

Native individuals not complying with the terms of becoming official citizens would be arrested as traitors and criminals

Those who would not separate from their native tribes and adapt to white culture would no longer have civil rights under the law
