Example Input: Question: What is the oldest city that was chosen for filming Aeon Flux? Passage:The screenplay was written by Phil Hay and Matt Manfredi, and directed by Karyn Kusama. It was based on the animated TV series by Peter Chung, who had a minor role in this film version of his work. In the early stages of production, actress Michelle Rodriguez was considered for the part of Æon. She had previously worked with Kusama in Girlfight. Kusama had originally suggested filming in Brasília, the capital of Brazil, because the 20th-century modern architecture of that city fit with her vision of Bregna. The producers rejected the idea because Brasília lacked the infrastructure and technical expertise to support a major film production. After several cities were scouted, Berlin and Potsdam in Germany were chosen for filming. Berlin had several locations that fit into the organic yet structured world of Æon Flux. The crew gained permission to film in several locations that had never allowed such access before, including the Treptow Crematorium, the Adlershof Trudelturm and Windkanal wind tunnel facility, and the Haus der Kulturen der Welt ("House of the World's Cultures"). Additional locations included the Bauhaus Archive and a dissection theatre built in 1790 to train veterinarians, part of the Berlin animal shelter. It was used as the Handler space. Filming was temporarily suspended for a month during September 2004 while Theron recovered from a neck injury she sustained during stunt-work on the tenth day of shooting. She was hospitalized in Berlin for five days and required about six weeks of physiotherapy to recover.

Example Input: Question: What year was the artist who painted Boleslaw I of Poland striking the Golden Gate with his sword born? Passage:Modern history accepts this gateway as one of three constructed by Yaroslav the Wise. The golden gates were built in 1017-1024 (6545 by the Byzantine calendar) at about the same time the Saint Sophia Cathedral was erected. Mentions of an older construction, such as the one presented on a painting by Jan Matejko of king Bolesław I of Poland striking the Golden Gate with his sword during the intervention in the Kievan succession crisis in 1018, it is now regarded a legend. Originally named simply the Southern Gate, it was one of the three main entrances to the walled city, along with the Ladski and Zhydivski (Polish and Jewish) Gates. The last two have not survived. The stone fortifications stretched for only 3.5 km. The fortification of the Old Kyiv (Upper City) stretched from the Southern Gates down to what is now Independence Square and where the Lechitic Gate was located. From there, the moat followed what is now Kostyol Street, skirting St. Michael's Monastery and continuing along today's Zhytomyr Street toward the Jewish Gates (at ). From there, the fortification stretched what is now Yaroslaviv Val ("Yaroslav's Rampart") Street back to the Southern Gate.
