Input: Consider Input: Question: Which team did Ferby lose to in the semi-finals of the 2001 Worlds? Passage:In 1999, Rycroft left the team to play with Ferbey's main rival, Kevin Martin. Rycroft was replaced by Marcel Rocque. The Ferbey Four that would dominate the Brier for the next few years was complete. Ferbey made his return to the Alberta provincials in 1999. While they didn't win, they did return in 2001 with a bang. They went on to winning not only the Alberta championship, but the 2001 Nokia Brier as well beating Kerry Burtnyk of Manitoba 8–4 in the final. This sent the team to the 2001 Worlds where they lost both their semi-final game and the bronze medal game, which they gave up to Pål Trulsen of Norway. In 2002, Ferbey won his fourth Brier, the 2002 Nokia Brier, which was his team's 2nd. They beat John Morris 9–4 in the final. This time, at the 2002 Worlds in Bismarck, North Dakota his team won the championship, beating the same Pål Trulsen, 10–5. Ferbey and his team would return to the Brier, at the 2003 Nokia Brier in Halifax, Nova Scotia. In the finals, they beat the home-town favourites Mark Dacey 8–4 in the finals. At the 2003 Ford World Curling Championship, his team won their 2nd world title, beating Ralph Stöckli of Switzerland 10–6 in the finals. The 2004 Nokia Brier was a blip on his team's record. After returning to the Brier for the fourth straight year, an unprecedented feat especially considering the great number of good teams in Alberta, his team would bow out in the final. After a 10–1 round-robin record, Ferbey and his team lost out to the same team they beat the previous year, Mark Dacey of Nova Scotia, in a 10–9 game where Ferbey's team surrendered a lead. However, Team Ferbey did not give up, and their reign would not be over. In 2005, the once again won the Alberta championships, and once again won the 2005 Canadian championships. This set a record, as his team became the first to win 4 championships as a team. The final was against Nova Scotia again, albeit a different team, that of Shawn Adams. In another close game, team Ferbey pulled it out and won 5–4 in the final. His trip to the 2005 Men's Ford World Curling Championships were marked with struggles, as the team finished the round-robin with three losses – tied for first with five other teams. After having a 4–3 record, Ferbey mounted eight straight wins to win the championship over David Murdoch of Scotland in a convincing 11–4 victory. Additionally, the Ferbey rink was the first team in history to score five on any single end in the world finals – and they managed this feat twice at the 2005 Ford World Curling Championships.

Input: Consider Input: Question: What city that was chosen for filming Aeon Flux has the largest population? 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.
