[EX Q]: Why are areas in Neolithic sudan no longer settled?, Context: During the Neolithic Era, before the onset of desertification, around 9500 BCE the central Sudan had been a rich environment supporting a large population ranging across what is now barren desert, like the Wadi el-Qa'ab. By the 5th millennium BCE, the people who inhabited what is now called Nubia, were full participants in the "agricultural revolution", living a settled lifestyle with domesticated plants and animals. Saharan rock art of cattle and herdsmen suggests the presence of a cattle cult like those found in Sudan and other pastoral societies in Africa today. Megaliths found at Nabta Playa are overt examples of probably the world's first known archaeoastronomy devices, predating Stonehenge by some 2,000 years. This complexity, as observed at Nabta Playa, and as expressed by different levels of authority within the society there, likely formed the basis for the structure of both the Neolithic society at Nabta and the Old Kingdom of Egypt.

[EX Q]: How was it formed?, Context: The archipelago is formed by high points on the rim of the caldera of a submarine volcano that forms a seamount. The volcano is one part of a range that was formed as part of the same process that formed the floor of the Atlantic, and the Mid-Atlantic Ridge. The top of the seamount has gone through periods of complete submergence, during which its limestone cap was formed by marine organisms, and during the Ice Ages the entire caldera was above sea level, forming an island of approximately two hundred square miles.
