question:
Question: Who succeeded Khalid's son as ruler of  the family's stronghold? Passage:Khalid was a member of the Shayban tribe, dominant in the region of Diyar Bakr in the northern Jazira, and third son of Yazid ibn Mazyad al-Shaybani, who served twice as Arab governor (ostikan) of Arminiya (a large province encompassing the whole of Transcaucasia). Khalid served in the same office no less than four times: in 813/814, 828–832, briefly in 841 and again under Caliph al-Wathiq (r. 842–845). In his first tenure, he showed himself conciliatory towards the native Christian population and the nakharar princes, but his second tenure was marked by the brutal suppression of several revolts by local Arab magnates, as well as the harsh treatment of the Christian population. As a result, when his re-appointment to the office was announced in 841, a rebellion broke out, forcing the Abbasid government to recall him immediately. Nevertheless, al-Wathiq assigned Arminiya to Khalid. The latter arrived in the province at the head of an army, and crushed any opposition. He died soon after at Dvin, where he was buried. He was succeeded by his son, Muhammad. His younger son Haytham ibn Khalid ruled in the family's stronghold of Shirvan, and was the first to claim the title of Shirvanshah.

Question: Who was the manager of Manchester United when Duncan Edwards died as a result of the Munich air disaster? Passage:The most famous former resident of the Priory Estate is Duncan Edwards, who was born two miles away at Holly Hall but moved to 31 Elm Road as a small child and went on to play 18 times for England as well as winning two Football League championships with Manchester United before he died in 1958 at the age of 21 from injuries sustained in the Munich air disaster. As a child, he had attended Priory Primary School and then Wolverhampton Street School. The school is most famous for being the former school (1941 to 1948) of the late Duncan Edwards, the former Manchester United and England footballer. He died aged 21 as a result of the Munich air disaster in 1958. After his death, a stained glass window was dedicated to Edwards at St Francis parish church at the junction of Laurel Road and Poplar Crescent. The church was founded during 1931 and originally based at Priory Hall before the church building on the newly developed housing estate was opened on 10 May 1932.

question:
Question: Which of the two players the Trail Blazers traded mid-season scored the most points during the 2003-04 season? Passage:The 2003–04 NBA season was the 34th season for the Portland Trail Blazers in the National Basketball Association. After years of off the court troubles and playoff underachieving, the Blazers under new General Manager John Nash, decided to rebuild. Throughout the season, the Blazers dealt away talented but troubled stars like trading Bonzi Wells, after losing his co-captain title, to the Memphis Grizzlies in November, and trading Rasheed Wallace to the Atlanta Hawks for Shareef Abdur-Rahim and Theo Ratliff in February. However, after appearing in only one game with the Hawks, Sheed was again traded to the Detroit Pistons for the rest of the season. The Pistons would eventually win the NBA Finals of that year, giving Wallace his first championship. The team also sent Jeff McInnis to the Cleveland Cavaliers for Darius Miles.
