question:
Question: How many miles long is the river that Silvanus drove the Alamanni tribesmen back from? Passage:Silvanus was born in Gaul, the son of Bonitus, a Laetic Frankish general who had supported Constantine I in the civil war against Licinius. Like so many other Franks of his times, and like his father before him, he was a loyal and thoroughly romanized "barbarian" in the military service of the Empire. By AD 351, he held the rank of tribune and was one of the senior officers who defected to Emperor Constantius II at the Battle of Mursa Major, after initially supporting the usurper Magnentius. An able soldier, Silvanus was eventually promoted to the rank of Magister militum per Gallias, a crucial post, then in AD 352-353, Constantius personally entrusted him with the difficult task of driving the Alamanni tribesmen raiding and looting in Gaul back beyond the Rhine, and restoring the fast eroding Roman authority in the province. This Silvanus fulfilled partly by bribing the Alamanni chieftains with the taxes he had collected, partly by defeating the Alamanni in battle and partly by suppressing the local bagaudae insurrections flaring up again in central and northern Gaul.

question:
Question: How many people attended the conference held near Berlin in January 1942? Passage:Following the invasion of Poland in 1939 most of the 3.5 million Polish Jews were rounded up and put into newly established ghettos by Nazi Germany. The system was intended to isolate the Jews from the outside world in order to facilitate their exploitation and abuse. The supply of food was inadequate, living conditions were cramped and unsanitary, and the Jews had no way to earn money. Malnutrition and lack of medicine led to soaring mortality rates. In 1941, the initial victories of the Wehrmacht over the Soviet Union inspired plans for the German colonisation of occupied Poland, including all territory within the new district of General Government. At the Wannsee Conference held near Berlin on 20 January 1942, new plans were outlined for the genocide of the Jews, known as the "Final Solution" to the Jewish Question. The extermination programme was codenamed Aktion Reinhard in German, to differentiate it from the Einsatzgruppen mass killing operations in territories conquered by Nazi Germany, in which half a million Jews had already been annihilated.

question:
Question: Who owned the Kansas City Kings during the 32nd annual NBA draft? Passage:The 1978 NBA draft was the 32nd annual draft of the National Basketball Association (NBA). The draft was held on June 9, 1978, before the 1978–79 season. In this draft, 22 NBA teams took turns selecting amateur U.S. college basketball players and other eligible players, including international players. The first two picks in the draft belonged to the teams that finished last in each conference, with the order determined by a coin flip. The Indiana Pacers won the coin flip and were awarded the first overall pick, while the Kansas City Kings, who obtained the New Jersey Nets' first-round pick in a trade, were awarded the second pick. The Pacers then traded the first pick to the Portland Trail Blazers before the draft. The remaining first-round picks and the subsequent rounds were assigned to teams in reverse order of their win–loss record in the previous season. A player who had finished his four-year college eligibility was eligible for selection. If a player left college early, he would not be eligible for selection until his college class graduated. Before the draft, five college underclassmen were declared eligible for selection under the "hardship" rule. These players had applied and gave evidence of financial hardship to the league, which granted them the right to start earning their living by starting their professional careers earlier. Prior to the start of the season, the Buffalo Braves relocated to San Diego and became the San Diego Clippers. The draft consisted of 10 rounds comprising the selection of 202 players.
