Why is a representative government necessary in a large society?

It would be like the government that is in the USA, it can't be a direct democracy as that would mean everyone votes on everything. Not only is it not efficient but also the general population often does not possess enough knowledge. That's why we have electoral college votes in USA because the people are not trusted.

B. Native Americans continue to face significant challenges on reservations that negatively impact their quality of life.

Explanation:

The reserves were established after the Indian Expulsion Act of 1830, through this law the British Settlers expelled the American tribes from their lands, to keep their lands and isolate them in small territories.

Currently, these reserves are scattered throughout the United States and have their own political, cultural and social processes. However, they face various problems related to the lack of job opportunities, family disintegration, high rates of drug use, and even cultural loss.
