Problem: The Celts who settled in Galatia came through Thrace under the leadership of Leotarios and Leonnorios circa 270 BC. They were defeated by Seleucus I in the 'battle of the Elephants', but were still able to establish a Celtic territory in central Anatolia. The Galatians were well respected as warriors and were widely used as mercenaries in the armies of the successor states. They continued to attack neighboring kingdoms such as Bithynia and Pergamon, plundering and extracting tribute. This came to an end when they sided with the renegade Seleucid prince Antiochus Hierax who tried to defeat Attalus, the ruler of Pergamon (241197 BC). Attalus severely defeated the Gauls, forcing them to confine themselves to Galatia. The theme of the Dying Gaul (a famous statue displayed in Pergamon) remained a favorite in Hellenistic art for a generation signifying the victory of the Greeks over a noble enemy. In the early 2nd century BC, the Galatians became allies of Antiochus the Great, the last Seleucid king trying to regain suzerainty over Asia Minor. In 189 BC, Rome sent Gnaeus Manlius Vulso on an expedition against the Galatians. Galatia was henceforth dominated by Rome through regional rulers from 189 BC onward.
Who sent Gnaeus Manlius Vulso on an expedition against the Galatians?
The answer is the following: Rome

Problem: Jim Foster, a promotions manager with the National Football League, conceived of indoor football while watching an indoor soccer match at Madison Square Garden in 1981. While at the game, he wrote his idea on a 9x12 envelope, with sketches of the field and notes on gameplay. He presented the idea to a few friends at the NFL offices, where he received praise and encouragement for his concept. After solidifying the rules and a business plan, and supplemented with sketches by a professional artist, Foster presented his idea to various television networks. He reached an agreement with NBC for a "test game".
In what year did Jim Foster conceive of the idea of arena football?
The answer is the following: 1981

Problem: As Western Europe witnessed the formation of new kingdoms, the Eastern Roman Empire remained intact and experienced an economic revival that lasted into the early 7th century. There were fewer invasions of the eastern section of the empire; most occurred in the Balkans. Peace with Persia, the traditional enemy of Rome, lasted throughout most of the 5th century. The Eastern Empire was marked by closer relations between the political state and Christian Church, with doctrinal matters assuming an importance in eastern politics that they did not have in Western Europe. Legal developments included the codification of Roman law; the first effortthe Theodosian Codewas completed in 438. Under Emperor Justinian (r. 527565), another compilation took placethe Corpus Juris Civilis. Justinian also oversaw the construction of the Hagia Sophia in Constantinople and the reconquest of North Africa from the Vandals and Italy from the Ostrogoths, under Belisarius (d. 565). The conquest of Italy was not complete, as a deadly outbreak of plague in 542 led to the rest of Justinian's reign concentrating on defensive measures rather than further conquests. At the emperor's death, the Byzantines had control of most of Italy, North Africa, and a small foothold in southern Spain. Justinian's reconquests have been criticised by historians for overextending his realm and setting the stage for the Muslim conquests, but many of the difficulties faced by Justinian's successors were due not just to over-taxation to pay for his wars but to the essentially civilian nature of the empire, which made raising troops difficult.
In what century did the economic revival in the Eastern Roman Empire end?
The answer is the following: 7th
