Once civilizations could grow excess food thousands of years ago, people in those societies soon learned to

A) make weapons to attack their rivals.

B) create religions with specific rules.

C) specialize in specific forms of labor.

D) build ships to begin exploring the world.

The correct answer is: C) specialize in specific forms of labor.

Explanation:

Thousands of years ago, everything was about hunting and growing in order to provide enough supplies to the family. Humans dedicated their time to farm, raise, to hunt and make food, as it is one of the basic human needs. However, once we got to have that much food so that we didn't have to worry about the supplies, the labor era began. People were then ready to develop, firstly, different kinds of craftwork and specialize in that field. Later on, that specific type of labor became the source of goods.

A) make weapons to attack their rivals.

People had made weapons long before and they even used to fight for food.

B) create religions with specific rules.

Enough food supplies is not one of the reasons religions were created.

D) build ships to begin exploring the world.

This may be one of the consequences, but that happened long after. Shipbuilding was one of the many specific forms of labor.
