Answer:
The correct response is Option D, started to farm.
Explanation:
Although there is some variation in this schema depending on the particular region or culture you are referring to, in general, human settlements into villages, towns, and cities don't occur until there is a surplus of food. In some Plains cultures in North America for example organized hunts were one reason to begin village settlement although they would also move with the migratory patterns of the animals and seasonality was important. Permanent, fixed villages tend to need at least horticulture to assure that there are ample resources for all the community members.
