Example Input: Question: How old was the Prime Minister when he announced he was stepping down? Passage:Melkert was elected as a Member of the House of Representatives after the election of 1986, taking office on 3 June 1986 serving as a frontbencher and spokesperson for Finances. After the election of 1994 Melkert was appointed as Minister of Social Affairs and Employment in the Cabinet Kok I, taking office on 22 August 1994. After the election of 1998 Melkert returned as a Member of the House of Representatives, taking office on 19 May 1998. Following the cabinet formation of 1998 Melkert per his own request asked not to be considered for a cabinet post in the new cabinet, he was seen as a rising star by the Labour Party leadership and was considered as the favorite son to succeed Wim Kok as the next Leader of the Labour Party and was selected as the Parliamentary leader of the Labour Party in the House of Representatives, taking office on 13 July 1998. The Cabinet Kok I was replaced by the Cabinet Kok II on 3 August 1998. In December 2001 the Leader of the Labour Party and incumbent Prime Minister Kok announced he was stepping down as Leader and that he wouldn't stand for the election of 2002, the Labour Party leadership approached Melkert as a candidate to succeed him, Melkert accepted and became the Leader of the Labour Party and Lijsttrekker (top candidate) for the election, taking office on 15 December 2001.

Example Input: Question: Who is the current owner of the team founded by Art Rooney? Passage:The Arizona Cardinals National Football League (NFL) franchise is allegedly suffering a curse by the citizens of Pottsville, Pennsylvania for undeservedly claiming the 1925 NFL championship from the Pottsville Maroons who were stripped of their title by the NFL in one of the greatest controversies in sports history. The curse will supposedly only be lifted when the championship is returned to Pottsville and to the correct shade of red team; this can only be met by overturning the original ruling, as Pottsville no longer has an NFL team and is too small to ever receive another one (with a metropolitan area roughly half the population of Green Bay, the league's smallest), making it impossible for the long-defunct Maroons to win another title. The Cardinals team holds the record for the longest championship drought, with their most recent championship coming in 1947, which is also the longest drought in American professional sports; the 1947 team was notable for having two of its members die during their playing careers within a year of each other, with Jeff Burkett dying in a plane crash following appendix surgery during the season and Stan Mauldin dying of a heart attack after a game the following season. Arizona also lost Super Bowl XLIII to another Pennsylvania team: the Pittsburgh Steelers (whose founder Art Rooney supported Pottsville's claim to the title). The franchise also leads the NFL in the total number of losses (730 through the 2017 season).

Example Input: Question: How many cylinders did the engine of the Fokker have? Passage:Parschau was assigned the Fokker A.III aircraft bearing both the Fokker factory serial number 216 and the IdFlieg military serial number of A.16/15. This airplane had previously been flown by Oberleutnant Waldemar von Buttlar. This unarmed monoplane had been privately purchased in 1913 by von Buttlar. It was requisitioned by the Fliegertruppe and von Buttlar was commissioned as an officer in the German Army at the outbreak of hostilities. The airplane was painted in a shade of green that was the same as that used by von Buttlar's previous Marburg-based Jager Regiment 11. Parschau had served with the same, Brieftauben-Abteilung Ostende unit, abbreviated as BAO in German military communications of the time, in Belgium as Oberleutnant von Buttlar did in November 1914, where the two German officers could have first made contact. As A.16/15 still bore the green color of von Buttlar's old unit, the aircraft became distinctive as Parschau's 'Green Machine', right from the outbreak of World War I. Parschau flew this machine on a roving commission for nearly a year, serving with FFAs 22 and 42 and the aforementioned "BAO" unit, which was actually a group of four FFA units operating as one for the Oberste Heeresleitung or OHL, the World War I German Army's High Command office. In this period, Parschau flew his distinctive machine on the Champagne front during October and November 1914. Following this were periods in Flanders and Alsace-Lorraine before Parschau was posted first to West Prussia and then on to Galicia on the Eastern Front. His travels were marked on the Fokker's fuselage. In late May 1915, this airplane was the first one to be fitted with a workable synchronization gear: the Fokker Stangensteuerung synchronizer, along with a Parabellum MG 14 machine gun for its armament. This airplane functioned as the prototype Fokker Eindecker for Parschau's use and combat evaluation.
