WOLVES:
The domestication of wolves was a pretty smooth move by early humans. It started off with the wild wolves looking over to the humans, seeing their warm fires and cooked food. The humans took pity on them and gave them some leftover food of theirs, but the wolves kept coming back. These became the first domesticated dogs, which evolved and adapted to human lives from then on. In return of the free food the humans gave them, they protected the humans from other wild animals, kept them company, and helped hunt.
LIVESTOCK:
Later on, people found out they could farm animals. Instead of always moving around to find their food, they kept their food with them. This started the Agricultural Revolution. Instead of being nomadic and never being to settle in one place, humans bult permanent houses, build fences to keep in sheep, goats, etc. and bred them to keep supply. From then, they never had to worry about finding food again because they always had a fresh surplus of meat, crops, and materials.

I don’t speak Spanish neither understand it
It is not an economic activity - it's linguistic in nature, not economic.
It is not linguistics either - linguistics is a scientific discipline.
It's also not a culture region - this would be a kind of region, and a region is not the same as spread of culture.
The correct answer is "a) cultural diffusion.
the answer is A
A potlatch is a gift-giving feast practiced by indigenous peoples of the <u><em>Pacific Northwest</em></u> Coast of Canada and the United States, among whom it is traditionally the primary economic system. This includes the Heiltsuk, Haida, Nuxalk, Tlingit, Makah, Tsimshian, Nuu-chah-nulth, Kwakwaka'wakw, and Coast Salish cultures. Potlatches are also a common feature of the peoples of the Interior and of the Subarctic adjoining the Northwest Coast, though mostly without the elaborate ritual and gift-giving economy of the coastal peoples.
