Which statement best evaluates the most significant features that promoted the river valley civilizations’ development?

Answer 1

The most significant features that promoted the development of river valley civilizations include the availability of fertile land, the presence of a reliable water source for irrigation, and the ability to support agriculture, which led to food surpluses. These factors fostered population growth, social stratification, and the establishment of complex societies with trade networks, writing systems, and centralized governments. The predictable flooding of rivers such as the Nile, Tigris, Euphrates, Indus, and Yellow River provided a stable agricultural environment that was essential for the emergence of these early civilizations.
