in history, civilizations were able to form once there was\na a priestly class.\nb a surplus of food.\nc an understanding of other languages.\nd an army to conquer surrounding peoples.
Answer
Brief Explanations:
A surplus of food is a fundamental requirement for the formation of civilizations. It allows for the development of specialized labor (such as priests, soldiers, etc.), urbanization, and the growth of complex social structures. A priestly class (A) is a part of a civilization's structure but not the initial cause. Understanding other languages (C) is not a prerequisite for civilization formation. An army (D) is more of a feature of an established civilization rather than a cause for its formation.
Answer:
B. a surplus of food.
