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: Did Eric Ashton win his first game against New Zealand? Passage:In 1954, Ashton was spotted playing rugby union during his national service in the Royal Artillery and was subsequently invited for a trial with Wigan. He attended the trial and was seen by the directors of the club as being a player with exceptional talent, after Wigan offered him a spot in their top level side he offered his home town club St. Helens the chance to sign him but they passed and he then signed for Wigan in 1955 for £150. He made his first representative later that year, appearing for Lancashire against New Zealand. He represented Rest of the World in the 11-20 defeat by Australia at Sydney Cricket Ground on 29 June 1957, and represented Great Britain & France in the 37-31 victory over New Zealand at Carlaw Park, Auckland on 3 July 1957. After signing for Wigan he quickly linked up with Welsh Billy Boston, and formed one of the most devastating right-hand side threequarters partnerships of modern times. Ashton played right-, i.e. number 3, in the 8-13 defeat by Oldham in the 1956–57 Lancashire County Cup Final during the 1957–58 season at Station Road, Swinton on Saturday 19 October 1957. He played and was captain in the 13–9 victory over Workington Town in the 1957–58 Challenge Cup Final during the 1957–58 season at Wembley Stadium, London on Saturday 10 May 1958, in front of a crowd of 66,109, such was the impact of both Ashton and Boston it led to Ashton being promoted as captain of the Wigan side after just two years at the club at the age of 22. It was a position he would go on to hold for the next twelve years. He made his international début at the age of 22 for the Great Britain side against France in 1957. He would go on to collect a total of 26 caps for the Great Britain side with his first Southern Hemisphere tour coming in 1957 as the British side competed in the World Cup. He was a true professional in every sense, being sent off just twice in his whole career and due to his professionalism, talent and intelligence he would go on to achieve a long and distinguished footballing career. Ashton's honours and achievements are nothing short of impressive, with 3 victorious Wembley Stadium Challenge Cup finals (out of a possible six), a Championship in 1960, a Lancashire Challenge Cup and two Lancashire League Championships as well as a BBC Floodlit trophy. He played , and was captain in Wigan's 30-13 victory over Hull F.C. in the 1958–59 Challenge Cup Final during the 1958–59 season at Wembley Stadium, London on Saturday 9 May 1959, in front of a crowd of 79,811.
