C) Contributions to the development of democracy.

Explanation:

The ancient or Archaic Greek period from 700 to 480 B.C reflects the formation of city-states and the development of the administrative set controlled by the wealthy aristocrats. the same kind of development was noticed in the period of the Roman Republic where the state was controlled by wealthy nobles. The autocratic rule in both these cities and its further development influenced the democratic set up of modern times.

the berlin blockade was an international crisis that arose from an attempt by the soviet union, in 1948–49, to force the western allied powers (the united states, the united kingdom, and france) to abandon their post-world war ii jurisdictions in west berlin. in march 1948 the allied powers decided to unite their different occupation zones of germany into a single economic unit. in protest, the soviet representative withdrew from the allied control council. coincident with the introduction of a new deutsche mark in west berlin (as throughout west germany), which the soviets regarded as a violation of agreements with the allies, the soviet occupation forces in eastern germany began a blockade of all rail, road, and water communications between berlin and the west. on june 24 the soviets announced that the four-power administration of berlin had ceased and that the allies no longer had any rights there.
