Question

how did the kansas - nebraska act of 1854 affect the indian tribes of the territory?
it forced their removal.
it extinguished indians treaty rights.
it left their status unaltered.
it guaranteed their traditional rights.

Explanation:

The Kansas - Nebraska Act of 1854 was a significant piece of legislation. It repealed the Missouri Compromise of 1820. One of its major impacts on Native American tribes was that it forced their removal. The act opened up large areas of land for settlement, which meant that Native American tribes who had treaties regarding that land were displaced. Treaties that were supposed to protect their land and rights were often ignored as settlers moved in. It did not guarantee their traditional rights (as it was more about white settlement and the slavery - related issue of popular sovereignty in the territories). And it certainly did not leave their status unaltered. While it may not have directly "extinguished" all treaty rights in a legal sense in one fell swoop (but rather through the process of removal and settlement that it enabled), the most direct and major impact was the forced removal of tribes from the affected territories.

Answer:

It forced their removal.
