Which of these statements is true?

The Indian Appropriations Act of 1871 ended the federal government’s practice of making treaties with Native American tribes, and tribes were no longer treated as independent nations for that purpose. The 1851 act established the reservation system, while the 1889 act opened some lands to white settlement; neither matches the claim in the other choices. Therefore, the true statement is that the 1871 act meant tribes were no longer classified as independent nations.
