PROBLEM: 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.

PROBLEM: Question: Which US Air Force plane that was shot down in Yugoslavia is the fastest? Passage:An important portion of the 1999 war between Yugoslavia and the NATO coalition involved combat between the Yugoslav Air Force, which was the predecessor of today's Serbian Air Force, and the opposing air forces of NATO. United States Air Force F-15s and F-16s flying mainly from Italian air force bases attacked the defending Yugoslav fighters—usually MiG-29s, which were in bad shape, due to lack of spare parts and maintenance. A total of six Yugoslav MiG-29s were shot down in 1999, of which three were shot down by USAF F-15s, one by a USAF F-16, and one by a RNAF F-16. One aircraft, according to a Serbian documentary, was hit by friendly fire from the ground. Another four were destroyed on the ground. During the course of the air war, Yugoslav anti-aircraft defenses downed a USAF F-16C and an F-117 Nighthawk, the first stealth aircraft to ever be shot down in combat.

PROBLEM: Question: What track was most successful of the album that included Kitty Kat? Passage:"Kitty Kat" received generally favorable reviews from critics. Eb Haynes of AllHipHop described "Kitty Kat" as a seductive track. Norman Mayers of Prefix Magazine wrote that B'Day is packed with standouts such as "the Rich Harrison-produced 'Freakum Dress' and the Neptunes-helmed 'Kitty Kat'." Picking out "Kitty Kat" as one of the four top tracks of the album, Spence D of IGN Music added that the song slows things down, allowing for Knowles' "crystal clear vocals to take some down time and relinquish up a dreamy, creamy sound that is playfully sensuous." Andy Kellman of Allmusic described "Kitty Kat" as "a deceptively sweet, rainbow-colored track" where purrs - that are sound made by all species of felids and are a part of cat communication - are more like "claws-out dismissals." Jon Pareles of The New York Times called the song a "cooing [and] sighing" one. Sal Cinquemani of Slant Magazine noted that "Kitty Kat" was "the only mid-tempo break" until the very end of the album. Darryl Sterdan, writing for the Canadian website Jam!, said that the song is just about what you think. Thomas Inskeep of Stylus Magazine commented that "Kitty Kat" seems to be an obvious tracks produced by The Neptunes. He went on complimenting "the squishy R&B keyboard which works well with the song’s 'I’m not feelin[g] it' vibe." A writer of the Seattle Post-Intelligencer commented, "Beyoncé is better at being sexy than sarcastic, and 'Kitty Kat' doesn't make any bones about what her absentee lover is missing." Michael Roberts of New Times Broward-Palm Beach commented that Knowles "purrs at lower speed" in the song.
