Passage: Elam was a pre-Iranic ancient civilization located to the east of Mesopotamia. In the Old Elamite period , Elam consisted of kingdoms on the Iranian Plateau, centered in Anshan, and from the mid-2nd millennium BC, it was centered in Susa in the Khuzestan lowlands. Its culture played a crucial role in the Gutian Empire and especially during the Iranic Achaemenid dynasty that succeeded it. The Oxus civilization was a Bronze Age Central Asian culture dated to c. 2300-1700 BC and centered on the upper Amu Darya . In the Early Bronze Age the culture of the Kopet Dag oases and Altyndepe developed a proto-urban society. This corresponds to level IV at Namazga-Tepe. Altyndepe was a major centre even then. Pottery was wheel-turned. Grapes were grown. The height of this urban development was reached in the Middle Bronze Age c. 2300 BC, corresponding to level V at Namazga-Depe. This Bronze Age culture is called the Bactria-Margiana Archaeological Complex . The Kulli culture, similar to those of the Indus Valley Civilisation, was located in southern Balochistan  c. 2500-2000 BC. Agriculture was the economical base of this people. At several places dams were found, providing evidence for a highly developed water management system.

How many years was the Kulli civilization located in southern Balochistan? How many years was the Oxus civilization dated to last? What levels of Namazga-Tepe did Oxus culture attain? What was considered the end of the bronze age? Which happend later, the Gutian Empire or the Iranic Achaemenid dynasty? Which two cultures were around in the year 2100 BC?
