Based on the map, which generalization best relates to
the cultures of the Pacific Northwest region?
O Large communities in the Pacific Northwest relied
primarily upon trade with the Plains Indians for their
prosperity, as the region was inhospitable to
agricultural activities.
Small, localized communities of the Pacific
Northwest specialized in a single, dominant
economic activity and traded with one another for
access to a variety of goods.
O Large communities in the Pacific Northwest utilized
a division of labor to develop a number of economic
activities and rarely traded with outsiders.
O Small communities of the Pacific Northwest entered
into a mutually beneficial confederacy for production
and procurement of goods, trade, and governance.

Answer: Small, localized communities of the Pacific Northwest specialized in a single, dominant economic activity and traded with one another for access to a variety of goods.

Explanation:

From the map we can see that in the Pacific Northwest the dominant economic activities were Agriculture and Fishing.

Judging by the location of the different groups firmly in one economic area, we can infer that they were small localized communities that specialized in a single, dominant economic activity.

The Paiute for instance specialized in Agriculture while the Pomo specialized in fishing. They then probably traded amongst themselves to have access to a variety of goods.
