Example Input: Question: When was the place founded that the Nobody's Perfect music video was shot in? Passage:Filmed in technicolor format, the music video for "Nobody's Perfect" was shot at Nu Boyana Film studios in Sofia, Bulgaria, on 24 March 2011 and was directed by Emil Nava. The music video premiered on 14 April 2011 in the United Kingdom through Jessie's Vevo channel. The music video is inspired by Lewis Carroll classic tale Alice's Adventures in Wonderland, Jessie J sits in a banquet table similar to the Mad Hatters' tea party. Jessie J is shown in a hall of doors that gives a resemblance to the curious hall in the first chapter of Alice in Wonderland. Jessie J also rolls in tar and appears dressed as the Roman goddess Libertas, who is better known as the robed female figure of the Statue of Liberty, what could be interpreted as Black-and-white dualism. After completing the filming sessions, Jessie J described the video as her favorite done so far.

Example Input: Question: Who is the oldest person recruited to join Demon Hunter? Passage:In 2003 they took a short break, during which McCaddon decided to leave Society's Finest, and went on to join Demon Hunter. After leaving Society's Finest and Embodyment, Ryan Clark and Don Clark, formerly of Training for Utopia, recruited him, Jesse Sprinkle, formerly of Poor Old Lu, and Jon Dunn (Who would later join Soul Embraced) to join their project, Demon Hunter. Demon Hunter already had an album before he joined. On this album McCaddon had contributed by photography. On his Demon Hunter debut, Summer of Darkness, was great success. In 2005, Ethan Luck, formerly of The O.C. Supertones and Project 86, replaced McCaddon. In 2006, former Embodyment members, Mark Garza (drums) and Andrew Godwin (guitar), contacted McCaddon and said they wanted to play metal again. McCaddon contacted former Society's Finest member, Nick Nowell (bass) and asked him to join their new project, The Famine. Though McCaddon knew people would compare the Famine to Embodyment, he stated that "We started The Famine because we wanted to get away from the stuff we were playing with Embodyment...".

Example Input: Question: How long had Christian VII been ruling Denmark for when he surrendered Oldenburg to Catherine the Great? Passage:In 1773, Christian VII of Denmark surrendered Oldenburg to Catherine the Great in exchange for her son and heir Paul's share in the condominial royal-ducal government of the Duchy of Holstein and his claims to the ducal share in the government of the Duchy of Schleswig; Oldenburg went to Frederick August, Administrator of the Prince-Bishopric of Lübeck, the representative of a younger branch of the family, and in 1777 the county was raised to the rank of a duchy. The duke's son William, who succeeded his father in 1785, was a man of weak intellect, and his cousin Peter, Administrator of the Prince-Bishopric of Lübeck, acted as regent and eventually, in 1823, inherited the throne, holding the Prince-Bishopric of Lübeck and Oldenburg in personal union.
