which factor prevented the mesopotamian city - states from uniting before 2400 bce?\nno ruler was powerful enough to take over the other city - states.\nthe city - states rarely interacted due to the distance between them.\nthe city - states were very diverse in their religious beliefs and practices.\nthe languages spoken in mesopotamia differed greatly among the city - states.
Answer
Brief Explanations:
Before 2400 BCE, Mesopotamian city - states were relatively independent. The geographical distance between them limited interaction. Rulers did try to expand (so the first option is incorrect). Mesopotamian city - states had some religious and cultural commonalities (so the third option is not the main factor). The language differences were not the primary barrier to unification compared to the distance - related lack of interaction.
Answer:
The city - states rarely interacted due to the distance between them.
