Passage: On 28 July 2012, Jin won the gold medal in the men's 10 m air pistol at the 2012 Summer Olympics. On 5 August, he won the gold medal in the 50m, becoming the first man to successfully defend the 50-metre pistol Olympic title. By doing so, Jin also became the first man to win the 10 metre air pistol and 50 metre pistol gold medals at the same Olympics, and one of the five shooters to win two individual gold medals at one Olympics, being the first man to have done so since Otto Olsen of Norway at the 1920 Summer Olympics. He is one of three shooters to have won three Olympic individual gold medals, along with Ralf Schumann of Germany and Kim Rhode of the United States. He became the first Korean athlete to win three individual Olympic gold medals, to win four (and five) individual Olympic medals, to defend an individual title in the Summer Olympics (while Sim Kwon-Ho won Olympic gold medals for Greco-Roman wrestling in 1996 and 2000, he won two different weight divisions), to win two individual gold medals at one Summer Olympic Games and to win an individual medal for one event at three consecutive Olympic Games (Kim Soo-Nyung won individual gold, silver and bronze medals respectively for archery in the 1988, 1992 and 2000 but these Olympics were non-consecutive).

Passage: After a spell at Colchester United where he scored once against A.F.C. Bournemouth, he joined Darlington at the start of the 2005–06 season, where he scored 10 goals in 21 league appearances. He moved to Cardiff City in January 2006, where he made 11 appearances including seven as substitute. He was released at the end of the season and signed by Gillingham. He scored his first goal for Gillingham away to Blackpool on 26 August 2006 in a game which ended 1–1. He struggled to hold down a place in the team during his first season at the club and was sent on loan to Bradford City the next season. He made his debut on 10 August 2007 and scored an equaliser to secure a 1–1 draw against Macclesfield Town. He played 18 league games, scoring six league goals for Bradford but his loan was not extended when it expired at the end of 2007 partly because of financial reasons. He returned to Gillingham but was immediately placed on the transfer list, and on 29 January 2008 he moved on a free transfer for a second spell at Darlington. Injury delayed his debut back at Darlington, which came on 23 February 2008 against Bury when he scored a sixth-minute penalty in a 2–1 victory. He played eight league games for Darlington, scoring three goals, and was a substitute in both legs of the play-off semi-finals against Rochdale, but after Darlington's defeat on penalties to Rochdale, he was released by manager Dave Penney. On 11 November 2010, Ndumbu-Nsungu was reported as training with Conference National side Tamworth with a view to signing. He trained with Beaconsfield SYCOB in December 2010, though the signing failed to materialise due to problems with international clearance.
 Link Information: In 2002 Penney retired to pursue a career in management and he remained at Doncaste Question: How many years was Penney a manager?
Answer: 15

Passage: Mike Ditka, a tight end for the Bears from 1961 to 1966, was hired to coach the team by George Halas in 1982. His gritty personality earned him the nickname "Iron Mike". The team reached the NFC Championship game in 1984. In the 1985 season the fire in the Bears–Packers rivalry was re-lit when Ditka used 315 pound defensive tackle "Refrigerator" Perry as a running back in a touchdown play at Lambeau Field, against the Packers. The Bears won their ninth NFL Championship, first since the AFL-NFL merger, in Super Bowl XX after the 1985 season in which they dominated the NFL with their then-revolutionary 46 defense and a cast of characters that recorded the novelty rap song "The Super Bowl Shuffle". The season was notable in that the Bears had only one loss, the "unlucky 13th" game of the season, a Monday night affair in which they were defeated by the Miami Dolphins. At the time, much was made of the fact that the Dolphins were the only franchise in history to have had an undefeated season and post-season. The Dolphins came close to setting up a rematch in the Super Bowl, but lost to the New England Patriots in the AFC title game. "The Super Bowl Shuffle" was videotaped the day after that Monday night loss in Miami.
