Example Input: Question: How many players recorded a Gordie Howe hat trick the year Lucic signed with the Bruins? Passage:In the 2007 off-season, Lucic signed an entry-level contract with the Bruins on August 2. He had been chosen as the Giants' next team captain, but made the Bruins' 2007–08 opening roster out of training camp. He played in his first career NHL game on October 5, 2007, a 4–1 loss to the Dallas Stars, in which he fought opposing forward Brad Winchester. His first goal came a week later on October 12 against Jonathan Bernier, a game winner, in an 8–6 win against the Los Angeles Kings. By also fighting Kings forward Raitis Ivanāns and notching an assist, he recorded a Gordie Howe hat trick (an unofficial statistic constituting a goal, an assist and a fight in one game). Unsure of whether the Bruins would keep him or return him to junior, he stayed in a downtown hotel in Boston to start the season. However, Lucic made enough of an impression during his first set of games with the Bruins, showing grit and consistent willingness to fight (he recorded 13 fighting majors in his rookie season), that they decided to keep him in the lineup. Bruins management informed the Giants prior to Lucic's tenth game, accounting for the NHL's nine-game maximum for junior-eligible players to stay with their NHL club without initiating their contract. He was chosen to participate in the 2008 NHL YoungStars Game and finished his rookie campaign with eight goals and 27 points. Towards the end of the season, he was voted by Bruins fans for the team's Seventh Player Award for exceeding expectations. Matched up against the first-seeded Montreal Canadiens in the opening round, Lucic scored his first Stanley Cup playoff goal in Game 3 on April 13, 2008. He finished his first NHL post-season with two goals as the Bruins were eliminated by the Canadiens in seven games.

Example Input: Question: Who was the manager of Manchester United when Duncan Edwards died as a result of the Munich air disaster? Passage:The most famous former resident of the Priory Estate is Duncan Edwards, who was born two miles away at Holly Hall but moved to 31 Elm Road as a small child and went on to play 18 times for England as well as winning two Football League championships with Manchester United before he died in 1958 at the age of 21 from injuries sustained in the Munich air disaster. As a child, he had attended Priory Primary School and then Wolverhampton Street School. The school is most famous for being the former school (1941 to 1948) of the late Duncan Edwards, the former Manchester United and England footballer. He died aged 21 as a result of the Munich air disaster in 1958. After his death, a stained glass window was dedicated to Edwards at St Francis parish church at the junction of Laurel Road and Poplar Crescent. The church was founded during 1931 and originally based at Priory Hall before the church building on the newly developed housing estate was opened on 10 May 1932.
