What influenced the way of life for both northwest coast Indians and plateau Indians?

Indigenous peoples of the Northwest Plateau, also referred to by the phrase Indigenous peoples of the Plateau, and historically called the Plateau Indians (though comprising many groups) are indigenous peoples of the Interior of British Columbia, Canada, and the non-coastal regions of the Northwestern United State

Their territories are located in the inland portions of the basins of the Columbia and Fraser Rivers. These tribes mainly live in parts of the Central and Southern Interior of British Columbia, northern Idaho, western Montana, eastern Washington, eastern Oregon, and northeastern California. The eastern flank of the Cascade Range lies within the territory of the Plateau peoples.[1]

There are several distinguishing features that differentiate plateau culture from the surrounding native cultures. These include a high reliance on roots, such as biscuitroot and camas, as a food source, a high reliance on short duration salmon and eel runs, and long-term habitation of winter villages at fixed locations along rivers or lakes. There was a lack of social stratification and a lack of tribal organization beyond the village level.

for the 2 countries u can do china and america because america has a democratic government while china has a communist government.

a democracy is a government run by the people either by directly voting or indirectly by electing representatives. an oligarchy is a government run by a few or a small group of people. a democracy and oligarchy are similar because both in an oligarchy and an indirect democracy, a small group of induvial determine the laws for a large group of people they are different because in an oligarchy it is easier to control and they do not have to answer to a large number of people in the country, unlike a democracy where they do have to answer to a large number of people an county that is a democracy would be the united states. a country that is an oligarchy would be the china.
