Example Input: Question: How many siblings did Khalid have in total? 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.

Example Input: Question: How old was John Hamilton, 1st Marquess of Abercorn, when his younger son was elected to Parliament? Passage:The younger son of John Hamilton, 1st Marquess of Abercorn, he was evidently educated at Harrow School, where he was a lieutenant of volunteers in 1803. He matriculated at Christ Church, Oxford on 24 October 1805, but left there for Cambridge, where he was admitted as a nobleman to St John's College on 19 October 1807. In the mean time, he was elected as Member of Parliament for Dungannon at the general election in May 1807, though underage, through the patronage of his father's political ally, Thomas Knox, 1st Viscount Northland. It was intended that he should later contest County Donegal or County Tyrone, but he suffered from illness, and may not ever have taken his seat. In January 1808, he sailed for Brazil in the brig Eclipse to recover his health, but died in Madeira in June.
