Example Input: Question: When was the creator of Conan the Barbarian born? Passage:"The Ivory Goddess" is a short story by American writers L. Sprague de Camp and Lin Carter, featuring the fictional sword and sorcery hero Conan the Barbarian created by Robert E. Howard. According to Morgan Holmes, citing de Camp friend Loay Hall, Carter did none of the writing, and the story was written by de Camp in collaboration with his wife Catherine Crook de Camp. The story was first published by Bantam Books in the paperback anthology Conan the Swordsman in August 1978. Later paperback editions of the collection were issued by Ace Books (1987 and 1991). The first hardcover edition was published by Tor Books in 2002. The book has also been translated into Italian. It was later gathered together with Conan the Liberator and Conan and the Spider God into the omnibus collection Sagas of Conan (Tor Books, 2004). The story has been translated into Italian.

Example Input: Question: How old was the Duke of Saxony when he appointed Adolf I to hold Holstein and Stormarn? Passage:He was appointed to hold as fiefs Holstein and Stormarn, including Hamburg, by Lothair, Duke of Saxony, in 1111. By this appointment Adolf became the leader of the defence of Germany against the Wagri. Allied with Henry, the prince of the Obotrites, he repeatedly waged war on Wagria and the Rugians. After Henry's death (1127), Adolf remained allied with his sons Canute and Sventepolk, but they were soon dead and Lothair, by then King of Germany, had made Canute Lavard, a Danish prince, Duke of Schleswig. Feeling his authority threatened by the Danish upstart, Adolf attacked his castle of Albergs, captured the garrison, and destroyed its defences. He left his counties intact to his second son, Adolf II, since his eldest, Hartung, had been killed in the Second Battle of Chlumec in 1126.

Example Input: Question: When was the field where "Refrigerator" Perry was used as a running back built? 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.
