The correct answer is: "the emergence of trade activities, job division and specialization".
The emergence of agriculture and animal domestication, enabled the accumulation of production surplus and gave rise to the first trade activities among human communities during the Neolithic era.
Trade, in turn, fostered job division and specialization. Different people started to be in charge of the different economic activities: hunting, gathering, animal domestication, agriculture, fabrication of tools, etc. The economic products that resulted from these activites were subsequently allocated among all the inhabitants in the country.
