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: In what round was Michael O'Connor drafted in 2015? Passage:During the following off-season in 2015, UBC Athletics would draw the Dinos head coach, Blake Nill away from the Calgary Dinos in what was the most high profile coaching change that year. Nill's impact was immediate as he was able to recruit quarterback Michael O'Connor, who was the ranked the sixth best quarterback by ESPN among the 2014 recruiting class. The Thunderbirds achieved a turnaround in Nill's debut season at the UBC helm to finish the 2015 regular season with a 6–2 record, placing second in the CWUAA standings. During the ensuing post-season drive of three straight single-elimination playoff games on the road, UBC upset the heavily favoured Calgary Dinos in the Hardy Cup game at Calgary; then defeated the St. Francis Xavier X-Men to earn its historical first Uteck Bowl victory at Antigonish, to advance to the national title game. In the 51st Vanier Cup championship, the Thunderbirds narrowly defeated the defending CIS champion Montreal Carabins, by scoring the game's last possession field goal to end the fourth quarter. The victory was UBC's fourth Vanier Cup overall, tying the Calgary Dinos for the all-time record among CWUAA member universities.
