Question: Who managed the Sweden footballers when they won gold in the 1948 Olympics? Passage 1:In 1996 Guillermo Martinez began wrestling under the name "Bombero Infernal", complete with a mask and ring gear adorned in flames and diabolical images. He had only worked under that name for just over a year when he became involved in a storyline feud against El Pantera, the rivalry escalated to the point where both wrestlers agreed to put their masks on the line in a Lucha de Apuestas, or "bet match", the most prestigious match type in Lucha Libre. The match took place on December 7, 1997 in International Wrestling Revolution Group's (IWRG) Arena Naucalpan in Naucalpan, State of Mexico with Bombero Infernal losing the match, which forced him to unmask in the middle of the ring, state his birthname and how long he had been a wrestler. Oftentimes losing the mask means the end of a specific ring character, but Martinez stuck with the Bombero Infernal ring characters in the years after his loss. On January 10, 1999 Bombero Infernal won the IWRG Intercontinental Middleweight Championship from Mr. Niebla and held the championship for 146 days straight. The title change was part of a long running storyline between Bombero and Mr. Niebla that saw Mr. Niebla regain the championship on June 6, 1999 but ultimately lose it to Bombero Infernal once again on October 24, 1999. His second reign ended at the hands of Último Vampiro on December 16, 1999 when he defeated Bombero Infernal. In late 2000 Bombero Infernal teamed up with Cripta and El Enterrador to defeat the team of Super Caló, Alan Stone and Moto Cross to win the Distrito Federal Trios Championship. On November 19, 2000 Bombero Infernal regained the IWRG Intercontinental Middleweight Championship from Último Vampiro. Bombero's time as a double champion ended on February 11, 2001 when Los Oficiales (Guardia, Oficial and Virgilante) won the DF Trios Championship. A month later he also lost the Middleweight Championship to Black Dragon. Later that year Bombero Infernal defeated Último Vampiro to win the Middleweight Championship for a fourth time, at the time someone other than the previous Último Vampiro was playing the character. The match between the two ended in a controversial fashion, leading IWRG to take the championship away from Bombero Infernal only one week later. In 2002 Bombero Infernal rekindled his storyline with El Pantera, going so far as to put his hair on the line against Pantera's Middleweight Championship, in a match that saw Bombero victoriously claim his fifth IWRG Intercontinental Middleweight Championship. His fifth reign lasted 95 days in total before it coming to an end when Tony Rivera defeated him. On November 11, 2002 Bombero Infernal, El Hijo del Diablo and El Engendro defeated Dr. Cerebro, Cirujano and Paramedico to win the DF Trios Championship once again, a title they would quickly lose to a new group called Los Megas (Mega, Omega and Ultra Mega)
 Passage 2:The Melrose Historic District is a nationally recognized historic district located in Iowa City, Iowa, United States. It was listed on the National Register of Historic Places in 2004. At the time of its nomination it consisted of 134 resources, which included 112 contributing buildings, one contributing site, 20 non-contributing buildings, and one non-contributing structure. This neighborhood first developed as a sparsely populated rural area, and between World War I and World War II developed into an automobile suburb. It grew along with the University of Iowa when it expanded to the west side of the Iowa River, and it borders the large University of Iowa Hospitals and Clinics complex. Among the prominent people who lived here was Howard Jones who coached the Iowa football team from 1916 to 1923. Other prominent residents included professors and local professionals and politicians. 
 Passage 3:The Sweden national football team has traditionally been a strong team in international football, with eleven World Cup appearances—collecting one silver and two bronze medals—and three medals in the Olympics, including one gold. Sweden played its first international game against Norway in 1908 and competed in an international tournament, the Summer Olympics, for the first time the same year. Since then, Sweden has regularly qualified for the World Cup and the Olympics as well as the European Championships. The best results in the World Cup are a second place (as hosts) in the 1958 and two third places in 1950 and 1994. In the Olympics, Sweden has won the gold medal in 1948 as well as two bronze medals in 1924 and 1952. The best result in the European Championship is a semi-final loss in 1992 as hosts of the tournament.
