Question

located across the red sea and the syrian desert from kush, there was the famous region of the fertile crescent called mesopotamia. framed by the tigris and euphrates rivers, it occupied what is now iraq. the area experienced the same cyclical flooding periods that ancient egypt and kush did, and thus had to learn to adapt. the difference is, this \land between rivers\ (the meaning of the origin of the name \mesopotamia\) had the flooding of not just one waterway but an entire flowing border to harness. however, like ancient egypt and kush, its location made it an ideal site for irrigation practices: as the people of the nile did, mesopotamians coaxed water into typically drier regions with canals. the land was routinely fertilized by rich silt washed up by the rivers; mesopotamia supported the harvest of barley, onions, grapes, apples, and turnips. cattle and sheep grazed on fertile grassland, and fishermen made a living selling and trading their catch. based on the reading passage above answer the following question: the economies, power, and survival of ancient mesopotamia, egypt, and the kingdom of kush depended on what?

Explanation:

The passage mentions that these regions had cyclical flooding periods which they adapted to, used for irrigation, and the flood - waters brought rich silt for fertilization. Their economies relied on agriculture (harvesting crops) and livestock grazing, which were made possible by the fertile land due to the rivers and their flooding.

Answer:

The economies, power, and survival of ancient Mesopotamia, Egypt, and the Kingdom of Kush depended on the cyclical flooding of rivers, which enabled irrigation and fertilization of the land for agriculture and livestock - rearing.
