What did the ancient Indus Valley, Huang, and Nile civilizations have in common?

a. they built pyramids to reach the gods
b. they elected leaders using potsherds
c. they developed and used gunpowder
d. they began in fertile river valleys<<<

D is correct.

The correct answer is d. they began in fertile river valleys.

All three civilizations, the ancient Indus Valley, Huang (Yellow River), and Nile civilizations, emerged and thrived in fertile river valleys. These river valleys provided the civilizations with fertile soil, abundant water supply, and facilitated agriculture, which contributed to the growth and development of these civilizations.

To find the answer to this question, you can conduct research on the ancient Indus Valley, Huang, and Nile civilizations. Here are the commonalities among these civilizations:

The correct answer is d. they began in fertile river valleys.

Explanation:
1. Ancient Indus Valley Civilization: This civilization thrived around the Indus River (now located in modern-day Pakistan and northwest India) during the Bronze Age (around 3300 BCE to 1300 BCE). One of the distinguishing features of this civilization was its well-planned cities, with sophisticated infrastructure and advanced drainage systems. The Indus Valley Civilization relied heavily on the fertile soil of the Indus River Valley for agricultural purposes.

2. Huang Civilization (also known as the Yellow River Civilization): This civilization developed along the Yellow River (Huang He) in ancient China, during the Neolithic and Bronze Ages (around 7000 BCE to 2000 BCE). Similar to the Indus Valley Civilization, the Huang Civilization benefited from the fertile soil provided by the Yellow River, which facilitated agricultural productivity and the growth of complex societies.

3. Nile Civilization: The Nile Civilization, also known as the Ancient Egyptian civilization, flourished along the banks of the Nile River in northeastern Africa. This civilization developed around 3100 BCE and lasted for several millennia. The Nile River's annual flooding brought nutrient-rich silt to the surrounding lands, creating exceptionally fertile soil called "black land." The Nile's fertile valleys allowed the Ancient Egyptians to engage in successful agriculture and sustain a complex civilization.

So, all three civilizations began in fertile river valleys, which played a crucial role in their development, supporting agriculture and providing the necessary resources for the growth of complex societies.
