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 on. She had previously worked with Kusama in Girlfight. Kusama had originally suggested filming in Brasilia, 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 Brasilia 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 on 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: When was the singer born who also sang on the Boy is Mine? Passage:In June 1998, Norwood released her second album Never Say Never. Boosted by the success of its number-one lead single "The Boy Is Mine", a duet with singer Monica, it facilitated Norwood in becoming a viable recording artist with mediacrossing appeal. In total, the album sold 16 million copies worldwide and spawned seven singles, including Norwood's second number-one song, the Diane Warren-penned "Have You Ever?". Also in 1998, Norwood made her big screen debut in a supporting role in the slasher sequel, I Still Know What You Did Last Summer, which garnered her both a Blockbuster Entertainment Award and an MTV Movie Award nomination for Best Breakthrough Female Performance. The following year, she co-starred with Diana Ross in the telefilm drama Double Platinum about an intense, strained relationship between a mother and daughter. Both Norwood and Ross served as executive producers of the movie which features original songs from Never Say Never and Ross's Every Day Is a New Day (1999).
