Answer:
The correct answer to the question: Based on these observations, what type of subsistence pattern do you think this group is using, would be: the hunter-gathering system of subsistence.
Explanation:
The case being exposed in this question is the typical example of the nomadic hunter-gatherers. This group of people will tend to be small, and they will subsist entirely on the resources readily available to them from the land and the hunting they can make close to their place of habitation. They did not have a stable place of living and tended to move from place to place in search of new readily, and easily acquirable, resources. They literally depended on what they could gather from plants, and the animals they could hunt from the wild. They did not farm, establish stable dwellings and did not domesticate animals.
