Question: Which team Torchetti has been assistant coach for has the best overall winning record? Passage:Before the 1999–2000 NHL season Torchetti was hired as an assistant coach for the Tampa Bay Lightning under Steve Ludzik. In 2002 Torchetti was hired as head coach of the San Antonio Rampage. Due to his many coaching stints in the city, "Torch" has kept close ties to San Antonio. After 65 games he was promoted to assistant coach with the parent club, the Florida Panthers. In 2004, he served 27 games as interim head coach, replacing Rick Dudley. He finished with a 10–12–4–1 record before being replaced by Jacques Martin. During the 2005–06 NHL season, Torchetti was hired by Dave Taylor as interim head coach of the Los Angeles Kings. With a chance to clinch a playoff spot, he had a 5–7 record in the team's final 12 games and was not retained by the Kings, instead being replaced by Marc Crawford.

Question: Who came second behind Diminuendo at The Oaks? Passage:In 1988 Melodist was ridden in all four of her races by Walter Swinburn. She did not run as a three-year-old until 22 May when she was sent to Italy for the Oaks d'Italia over 2400 metres on soft ground at the San Siro racecourse in Milan. The finish of the race was dominated by overseas challengers as Melodist won by one and a half lengths from her fellow British raider Asl (previously second in the Musidora Stakes) with the French-trained Summer Trip a neck away in third. On 9 July Melodist was one of nine runners to contest the Irish Oaks over one and a half miles at the Curragh and started at odds of 11/1. The 2/9 favourite for the race was Diminuendo, ridden by Steve Cauthen, who had won The Oaks by four lengths. Both Melodist and Diminuendo were owned by Sheikh Mohammed and based at Newmarket, but whereas Melodist was trained by Stoute, the favourite was trained by Henry Cecil at Warren Place. The other fancied runners were Dancing Goddess (second in the Irish 1000 Guineas), Miss Boniface (Ribblesdale Stakes) and Silver Lane (Prix de la Grotte). Melodist tracked the leaders before overtaking Miss Boniface before going to the front a furlong and a half from the finish. She faced a strong late challenge from Diminuendo and after a sustained struggle the two fillies crossed the line together with the judge declaring a dead heat.

Question: Did Olvir Hnufa's father die before his brother-in-law? Passage:Olvir Hnufa or Ölvir hnúfa was a Norwegian commander in a clan and poet of the late ninth and early tenth centuries, known from, among other sources, Egil's Saga, Skaldatal and the Prose Edda. Olvir was the son of the viking Berle-Kari and brother-in-law of Kveldulf Bjalfason, who married Olvir's sister Salbjorg Karadottir; he was thus uncle to Skallagrim and Thorolf Kveldulfsson and great uncle to the famous poet Egil Skallagrimsson. Olvir also had a brother named Eyvind Lambi. Olvir was a prominent member of the court of King Harald Fairhair, who united Norway under his rule in the late ninth or early tenth century. Among other famous poets, he served as one of King Harald's court poets. He also served as a warrior in Harald's retinue, and fought at the pivotal Battle of Hafrsfjord on the king's flagship. He is best known for his involvement in the conflict between Harald and Olvir's kinsman Thorolf Kveldulfsson, which ended with the latter's death. Only a few fragments of Olvir's poetry survive.
