Final answer:
The statement that Neolithic farmers formed a society because they needed to cooperate to irrigate the land is true, as agricultural production and the need for irrigation systems required coordination and collective effort, leading to the formation of early societies.
Step-by-step explanation:
Neolithic farming communities likely formed societies for multiple reasons, including the need to cooperate to irrigate the land, which is why the answer to the question 'Neolithic farmers formed a society because they needed to cooperate to irrigate the land' is A. True. The Neolithic Revolution brought about the need for collective labor and effort in terms of agriculture. The construction of irrigation systems, especially in areas prone to unpredictable flooding like Mesopotamia, required coordination and cooperation among groups. The societal structures that emerged during this time facilitated not only farming but also the development of various roles, including religious practices, governance, and the division of labor. The excess production of food allowed for population growth, leading to the formation of larger communities and cities, where the surplus food produced by farmers was distributed among people who contributed to the community in other ways.
