What can one infer from the above illustration?

(A) Farming practices relied on human labor. (B) There was extensive use of irrigation. (C) Farming was the exclusive purview of women. (D) Animals were valued too highly to be used in the fields.Explanation: Human, not animal, labor was used to prepare the land and to plant and harvest crops. There is no evidence of irrigation in the image (B), and both men and women are at work (C). Animals were not generally used in farm work, not because they were “too valuable,” but because they fulfilled other tasks (D).
