There are many thoughts on the origins of civilization. One of the major factors involved was the increase in population. The development of techniques, primarily irrigation and flood control, which permitted agriculture in special areas such as the flood plain of the Tigris and Euphrates rivers, made possible the support of large population. Once populations reach a certain number, the older pattern of social organization breaks down and new ones develop. Specifically the older system, whereby each individual participated in food production and maintained a similar standard of living and whereby kinship  served as the basic method of social organization, was replaced by the occupational division of labor, political and religious hierarchies , public works such as road and public building construction, class systems, codes of law, markets, new forms of warfare, and urban centres. Allied with these important sociological traits are material traits, such as monumental architecture and the development of science and, in many cases, metallurgy  and writing systems. The earliest civilization, Sumer, developed in the Middle East. This was the Bronze Age of the Old World, during which people first developed the art of metallurgy, civilization also arose in other parts of the Old World, first in Egypt, China, and India, and later in Europe and Africa. At this time, civilization also developed independently in the New World, in the Mexican area and in Peru and its adjacent  areas. In the Old World the Bronze Age was followed by the Iron Age, which saw the rise and fall of great empires and the shift of power from the Middle East to Greece and Rome and then to Western Europe. In the 1700s the Industrial Age began, leading directly to the modern civilization of today. Which of the following is NOT included in the expression "the Old World" used in the passage?
American continent. Both Western and Eastern Europe. African continent. Asian countries.
