Problem: During the later Roman Empire, the principal military developments were attempts to create an effective cavalry force as well as the continued development of highly specialised types of troops. The creation of heavily armoured cataphract-type soldiers as cavalry was an important feature of the 5th-century Roman military. The various invading tribes had differing emphasis on types of soldiersranging from the primarily infantry Anglo-Saxon invaders of Britain to the Vandals and Visigoths, who had a high proportion of cavalry in their armies. During the early invasion period, the stirrup had not been introduced into warfare, which limited the usefulness of cavalry as shock troops because it was not possible to put the full force of the horse and rider behind blows struck by the rider. The greatest change in military affairs during the invasion period was the adoption of the Hunnic composite bow in place of the earlier, and weaker, Scythian composite bow. Another development was the increasing use of longswords and the progressive replacement of scale armour by mail armour and lamellar armour.
What was the primary military arm of Anglo-Saxon armies?
The answer is the following: infantry

Problem: The Ubaid period is marked by a distinctive style of fine quality painted pottery which spread throughout Mesopotamia and the Persian Gulf. During this time, the first settlement in southern Mesopotamia was established at Eridu (Cuneiform: NUN.KI), c. 5300 BC, by farmers who brought with them the Hadji Muhammed culture, which first pioneered irrigation agriculture. It appears that this culture was derived from the Samarran culture from northern Mesopotamia. It is not known whether or not these were the actual Sumerians who are identified with the later Uruk culture. Eridu remained an important religious center when it was gradually surpassed in size by the nearby city of Uruk. The story of the passing of the me (gifts of civilization) to Inanna, goddess of Uruk and of love and war, by Enki, god of wisdom and chief god of Eridu, may reflect this shift in hegemony.
During the Ubaid, where was the first settlement in southern Mesopotamia established?
The answer is the following: Eridu
