Example Input: Question: How old was the person who escaped to Africa when Cleopatra ascended to the throne? Passage:Caesar crossed the Rubicon accompanied by the XIII Legion to take power from the senate in the same way that Sulla had done in the past. Formally declared an enemy of the state, Caesar pursued the Senatorial party, now led by Pompey, who abandoned the city to raise arms in Greece. Cato was sent to Sicily to secure control of the grain supply. After securing control of Italy, Caesar sent the praetor Curio with four legions to Sicily. Cato's garrison was insufficient to withstand a force of this magnitude, he abandoned the island and went to Greece to join Pompey. After first reducing Caesar's army at the siege battle of Dyrrhachium, where Cato commanded the port, the army led by Pompey was ultimately defeated by Caesar in the Battle of Pharsalus (Cato wasn't present during the battle, Pompey had left him in command of Dyrrhachium). Cato and Metellus Scipio, however, did not concede defeat and escaped to the province of Africa with fifteen cohorts to continue resistance from Utica. Caesar pursued Cato and Metellus Scipio after installing the queen Cleopatra VII on the throne of Egypt, and in February 46 BC the outnumbered Caesarian legions defeated the army led by Metellus Scipio at the Battle of Thapsus. Acting against his usual strategy of clemency, Caesar did not accept surrender of Scipio's troops, but had them all slaughtered.

Example Input: Question: Which of the lead actors in the Heat pilot episode is the oldest? Passage:In 1979, Mann wrote a 180-page draft of Heat. He re-wrote it after making Thief in 1981 hoping to find a director to make it and mentioning it publicly in a promotional interview for his 1983 film The Keep. In the late 1980s, he offered the film to his friend, film director Walter Hill, who turned him down. Following the success of Miami Vice and Crime Story, Mann was to produce a new crime television show for NBC. He turned the script that would become Heat into a 90-minute pilot for a television series featuring the Los Angeles Police Department RobberyHomicide division, featuring Scott Plank in the role of Hanna and Alex McArthur playing the character of Neil McCauley, renamed to Patrick McLaren. The pilot was shot in only nineteen days, atypical for Mann. The script was abridged down to almost a third of its original length, omitting many subplots that made it into Heat. The network was unhappy with Plank as the lead actor, and asked Mann to recast Hanna's role. Mann declined and the show was canceled and the pilot aired on August 27, 1989 as a television film entitled L.A. Takedown. which was later released on VHS and DVD in Europe.

Example Input: Question: What age was Canut VI the year he led a Danish expedition that destroyed Groswin burgh? Passage:Groswin took over the position of nearby Altes Lager Menzlin as a trade center after its decline in the 9th century. The tribal affiliation of the inhabitants, though associated with the greater tribe of the Veleti, is uncertain - while the Ukrani are reported to have dwelled south of the Zarow and the Rani north of the Ryck river, the name of the medieval inhabitants of the area between these rivers is not reported. The lands of Groswin became a castellany of the Duchy of Pomerania during the westward expansion of Wartislaw I in the 1120s, and became part of the Bishopric of Cammin in 1140. In 1153, Stolpe Abbey was founded in the Groswin castellany as the first Pomeranian monastery. A market at the Groswin burgh is documented in 1159. In 1185, a Danish expedition led by Canut VI destroyed the burgh and devastated the castellany. Though the name Groswin stayed in use to refer to the area, the position of the former burgh as the areas center was taken over by nearby Anklam.
