During the time period 8000 to 600 bce, people from which region farmed the fertile soils of the yellow river valley?

a) northern africa
b) mesopotamia
c) the andes mountains
d) east asia

The answer is letter D. Because of the fertile soils of the Yellow River Valley, East Asian countries, like Mongolia, started farming. Many root crops had grown well in this fertile soil. Asians were able to make a living out of farming and trade on the Yellow River.

The statistics for the eastern war are grim. more than three-million men died in the fighting, more than nine-million men were wounded, and every major country which participated lost its form of government.
