Example Input: Question: Which occured first, Ali's refusal to go to Vietnam or his being stripped of his championship? Passage:The fighters discuss their bouts against Muhammad Ali as well as their own lives and careers; Ali's fights against other opponents; his conversion to Islam and the assumption of the name Muhammad Ali; his relationship with the Nation of Islam organization (frequently referred to as the "black Muslims"), its leader, Elijah Muhammad (who bestowed Ali with his new name after he was briefly called Cassius X), and the Nation of Islam's most prominent minister, Malcolm X; Ali's refusal to be inducted into the United States Army to serve in the ongoing Vietnam War in 1967 on moral and religious grounds; the decision by the New York State Athletic Commission to strip him of his championship; his legal case and his reinstatement after the favorable June 28, 1970 decision by the Supreme Court of the United States. The Justices decided 8–0 (with Thurgood Marshall abstaining), that "... for the reasons stated, that the Department [of Justice] was simply wrong as a matter of law in advising that the petitioner's beliefs were not religiously based and were not sincerely held".

Example Input: Question: How many years after Thorgerson designed the cover with the man on fire for Pink Floyd did he pass away? Passage:Storm Thorgerson, who had done the majority of album covers for Pink Floyd, did the Echoes art which features recursive windows in an infinite regression as a nod to his own cover for 1969's Ummagumma, and the objects on each landscape refer to the Pink Floyd discography. For instance, there's the man on fire from Wish You Were Here, another wearing the Delicate Sound of Thunder lightbulb suit, dolls of the Atom Heart Mother cow and the Animals pig, a bike and both a brick wall and the hammers from The Wall. Eventually Thorgerson opted to make two images, with another used for the back cover. To create the idea on a photograph, various walls - which had varied measurements and angles to ensure that "nothing seemed to fit other than by eye through the lens." - were built and put in a country landscape in Sussex. Actors, props and fittings were set in and between those walls. The original design was one of two sketches submitted for Dream Theater's 1997 album Falling into Infinity, with the original being framed and hanging in the home of former Dream Theater drummer Mike Portnoy and is pointed out by Portnoy in his Hudson Music instructional drum DVD In Constant Motion.

Example Input: Question: How many members make up the Coodbeen Champions along with Greg Champion? Passage:Football humorists the Coodabeen Champions have written many songs about the sport since the Coodabeens Footy Show first aired in 1981. Greg Champion, the team's main songwriter, wrote the 1994 hit "That's the Thing About Football". Other titles include "VFL Park in the Dark", "Deep in Our Hearts Everyone Barracks for Fitzroy", "Matty Lloyd Throws Grass in the Air", "Knee Reconstruction" and "Dermott Brereton is a Hood". In 1994, actor Eric Bana released the album Out of Bounds in which he lampoons popular football identities. "Out of Bounds" is also a song by bawdy balladeer Kevin Bloody Wilson, parodying personalities on The Footy Show. In 1981, television's Ugly Dave Gray proposed a new club song with "Come on Fitzroy". Comedian Austen Tayshus released "Footyana" in 1999, a spoken-word single in the style of "Australiana" (1983). "Kicking the Footy with God" by The Bedroom Philosopher is about Gary Ablett, Sr. ("God"), released on his 2005 debut album In Bed with My Doona. Sidewinder's Nick Craft penned "It's a Draw" in response to the 2010 AFL Grand Final.
