Example Input: Question: What year was the prize that the Assemble collective received first given out? Passage:Nottingham is a research-led institution, and two academics connected with the university were awarded Nobel Prizes in 2003. Clive Granger was jointly awarded the Nobel Prize in Economics. Much of the work on Magnetic Resonance Imaging (MRI) was carried out at Nottingham, work for which Sir Peter Mansfield received the Nobel Prize for Medicine in 2003. Nottingham remains a strong centre for research into MRI. The university has contributed to a number of other significant scientific advances. Frederick Kipping, Professor of Chemistry (1897–1936), made the discovery of silicone polymers at Nottingham. Major developments in the in vitro culture of plants and micropropogation techniques were made by plant scientists at Nottingham, along with the first production of transgenic tomatoes by Don Grierson in the 1980s. Other innovations at the university include cochlear implants for deaf children and the brace-for-impact position used in aircraft. In 2015, the Assemble collective, of which the part-time Architecture Department tutor Joseph Halligan is a member, won the Turner Prize, Europe's most prestigious art award. Other facilities at Nottingham include a 46 teraflop supercomputer.

Example Input: Question: How old was Gabriel Bethlen when his forces sacked Vienna? Passage:At the time, the Thirty Years' War was raging across Europe. Gabriel Bethlen, prince of Transylvania saw an opportunity to unite the two Hungarian principalities, Transylvania and Royal Hungary, and sacked Vienna in November 1619. He also asked Sultan Osman II for aid, but this was unsuccessful. The Commonwealth was relatively uninvolved in this war but the Polish king, Zygmunt III Waza, sent an elite and ruthless mercenary unit, the Lisowczycy, to aid his Habsburg allies. They defeated the Hungarian lord George Rákóczi at the Battle of Humenné in 1619, and thus, cut the supply lines of Transylvanian forces. Then Gaspar Graziani, ruler of Moldavia, switched sides and joined Poland.

Example Input: Question: What was the population of Los Angeles the year that Spears did her interview with Seacrest? Passage:"Piece of Me" was co-written and produced by the Swedish duo Christian Karlsson and Pontus Winnberg, professionally known as Bloodshy & Avant, along with Klas Åhlund. While recording with Spears over the years, Karlsson and Winnberg often saw first-hand how her regular activities were interrupted by the paparazzi, including one experience in Hamburg which Winnberg deemed "really scary". For Blackout, Spears worked with them on "Radar", "Freakshow" and "Toy Soldier". When the album was considered to be finished, Bloodshy & Avant were persuaded by her A&R Teresa LaBarbera Whites to work on a new track. Winnberg commented that it had always been an unwritten rule not to write songs about Spears's personal life since the label rejected "Sweet Dreams My LA Ex", a response track to Justin Timberlake's "Cry Me a River". However, the duo wrote "Piece of Me" with Åhlund and sent it to Spears, who loved it. Bloodshy & Avant worked on the track at Bloodshy & Avant Studios in Stockholm, Sweden, and Spears recorded her vocals at Chalice Recording Studios in Los Angeles, California. Winnberg stated that Spears was extremely psyched when she came to the studio, where she recorded the song in about half an hour as she had learned the lyrics by heart in her car. "Piece of Me" was later mixed by Niklas Flyckt at Mandarine Studios in Stockholm. On October 31, 2007, during a radio interview with Ryan Seacrest, Spears talked about the song, saying,
