WORLD CIVILIZATION

Detailed explanation-1: -As farmers began to produce more surpluses, villages did not need as many farmers to grow food. As a consequence, some people began specializing in other types of work such as making pottery or weaving cloth. Specialized workers also created surpluses and traded their goods for food or other services.

Detailed explanation-2: -With food surpluses, workers can specialize in jobs that require special skills. For instance, Sumerian workers built houses, sewed clothes, created pottery, and cooperated on building public projects such as ziggurats and irrigation canals.

Detailed explanation-3: -Job specialization allowed for people to develop and contribute important skills to help maintain their civilization. An individual could not develop all the skills needed to maintain specific items and tasks. Most people in early civilizations were farmers. Rulers and soldiers helped to protect and keep order.
