Answer:
D. The Abbasid state was headed by a caliph who was theoretically the state's supreme religious and political leader.
Explanation:
Caliphs concentrated in their hands religious and political power. The Abbasid caliphs, who reproached their Umayyad predecessors for behaving like secular rulers, tried to outline their own approach to government in Islamic terms and, accordingly, to the extent that they managed, they tried to adhere to a religious orientation in politics.

To get more resources and land. i got this from a text book
A valley is an elongated low area often running between hills or mountains, which will typically contain a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period of time. Some valleys are formed through erosion by glacial ice. These glaciers may remain present in valleys in high mountain or polar areas. At lower latitudes and altitudes, these glacially formed valleys may have been created or enlarged during ice ages but now are ice-free and occupied by streams or rivers. In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In areas of limestone bedrock, dry valleys may also result from drainage taking place underground rather than at the surface. Rift valleys arise principally from earth movements, rather than erosion. Many different types of valley are described by geographers, using terms that may be global in use or else applied only locally.
