Answer:
A. Growth of urbanization
Explanation:
The map of medieval Paris shows that there are more settlements concentration at the center indicating the growth of an urban society where more individuals built houses near the center.The dense settlement could have been caused by improved farming and food surpluses that eventually required proper storage which encourage trade. The map shows well established roads that could have encouraged a reduced costs of transport facilitating movement of goods and people thus bringing them together in a central place.Improved agricultural practices and presence of good roads connecting the area could have contributed to the growth of urbanization as evident on the map.
Answer: The high antiquity of civilization in the Middle East is largely due to the existence of convenient land bridges and easy sea lanes passable in summer or winter, in dry or wet seasons. Movement of large numbers of people north of the Caspian Sea was virtually impossible in winter, owing to the severity of the climate; central Eurasia was often too dry in summer. Land passage between Asia and Africa was in early times limited to narrow strips of land in the Isthmus of Suez. Large-scale desert travel was limited to special routes in Iran and in North Africa, both east and west of the Nile Valley.
