Example Input: Question: Around what age was Ingmar Bergman when he rose to prominence? Passage:The famous and influential Swedish filmmaker, Ingmar Bergman, rose to prominence in the fifties. He began making films in the mid-forties, and in 1955, he made Smiles of a Summer Night, which brought him international attention. A year later, he made one of his most famous films, The Seventh Seal. In the 1960s, Bergman won the Academy Award for Best Foreign Language Film for two consecutive years, with The Virgin Spring (Jungfrukällan) in 1960 and Through a Glass Darkly (Såsom i en spegel) in 1961. He won the award again in 1983, for the early twentieth-century family drama Fanny and Alexander (Fanny och Alexander). Bergman has also been nominated for the Best Picture award once, with the 1973 Cries and Whispers (Viskningar och rop), the story of two sisters watching over their third sister's deathbed, both afraid she might die, but hoping she does. The film lost to The Sting, and oddly enough, it was not nominated in the Foreign Language Film category. It also gave Bergman the first of three nominations for Best Director. Ingmar Bergman also won four Golden Globe Awards for Best Foreign Language Film.

Example Input: Question: When was the place where the Cyclones play home games built? Passage:The 2011 Iowa State Cyclones football team represented Iowa State University in the 2011 NCAA Division I FBS football season. The Cyclones were led by third year head coach Paul Rhoads and play their home games at Jack Trice Stadium. They are a member of the Big 12 Conference. The conference play began with a loss at home to the Texas Longhorns, and ended with a loss at Manhattan, Kansas to the Kansas State Wildcats in the Farmageddon series, with a 3–6 record. The season will likely be remembered for the game against then #2 Oklahoma State Cowboys, who the Cyclones upset in a double-overtime thriller throwing the BCS into "utter chaos" as dubbed by sports media. The Iowa State squad was invited to the first Pinstripe Bowl game, which they were defeated by Rutgers, and the Cyclone's 2011 season came to a close with 6–7 overall record, 3–6 in Big 12 play, finished 8th place.

Example Input: Question: On what album was the Gerry Rafferty song from that is referenced in the show? Passage:While telling Bart and Lisa about 1990, Homer says, "Tracey Ullman was entertaining America with [...] crudely drawn filler material." This is a reference to The Simpsonss debut as "bumpers" airing before and after commercials on The Tracey Ullman Show. The song "Those Were the Days" parodies the opening credits of the television show All in the Family. One of the people who run over the saxophone is a man on a tricycle, who promptly falls over. This is a reference to the show Rowan & Martin's Laugh-In. At the beginning of the flashback, the song "Don't Worry, Be Happy" by Bobby McFerrin can be heard. In the flashback, Dr. Hibbert fashioned his hair and attire like Mr. T in The A-Team. Homer can be seen watching Twin Peaks and The Giant is then shown waltzing with the White Horse. In King Toot's music store, when Homer buys Lisa her first saxophone, there is a guitar in the background that is similar to Eddie Van Halen's "Frankenstrat" guitar. The photo beside Kent Brockman on the news has him modeled after the Coppertone Girl. At the end of the episode, Lisa performs a brief, cruder rendition of the hook of "Baker Street" by Gerry Rafferty on her new saxophone before the music segues into the original song.
