Example Input: Question: How many total albums have the Swedish pop group ABBA released? Passage:The Definitive Collection is a 2001 compilation album of all the singles released by Swedish pop group ABBA. It consisted of two discs: the first featuring the singles from 1972–79 ("People Need Love" to "Does Your Mother Know"), and the second including the singles from 1979–82 ("Voulez-Vous" to "Under Attack"), with the tracks being listed in chronological order. The main exception is the track "Thank You for the Music", which, despite being written and recorded in 1977, was in fact released as a single (primarily in the UK) in 1983 after the band had split up. It appears on disc two, along with two bonus tracks, "Ring Ring" (1974 UK single remix), and "Voulez-Vous" (1979 US promo extended remix). The Australian version of The Definitive Collection adds a further two bonus tracks: "Rock Me" and "Hasta Mañana". The 1974 remix of "Ring Ring" is the first appearance on CD of this version mastered from the original master tape, after the UK single master tapes had been returned to Polar Music by the former UK licensees, Epic Records. The track's previous appearance on CD, in a 1999 singles boxed set, was mastered from a vinyl single.

Example Input: Question: Where was Thomas Kenan's great grandfather born? Passage:Thomas Stephen Kenan (February 12, 1838 – December 23, 1911) was a Confederate soldier, and later a politician. His parents were Sarah Rebecca Graham and Owen Rand Kenan; he was the grandson of U.S. Congressman Thomas Kenan and great-grandson of Revolutionary War general James Kenan. He started his education in Duplin County, North Carolina at Old Grove Academy in Kenansville (the town was named for his great-grandfather in 1818). Later he spent a year at Central Military Institute in Selma, Alabama. Thomas spent his freshman year of college at Wake Forest in June. Thomas then transferred his sophomore year to the University of North Carolina, where he would graduate in 1857. He studied law for two years with Judge Pearson at Richmond Hill where he practiced law in Kenansville. After graduation and during the Civil War he became Captain of the Duplin Rifles in the Confederate States Army, elected lieutenant colonel of the 43rd North Carolina Infantry Regiment in April 1862, and was promoted to colonel later that year. He was wounded at the Battle of Gettysburg. While on an ambulance train, he and his older brother James Kenan were both captured; they were then imprisoned on Johnson's Island, Ohio. On March 22, 1865, he was released on parole but never switched sides during the war. On his return home he was elected to the state legislature from 1865 to 1867. Later that year he ran for Congress and lost. Not letting that defeat end his political career, he moved to Wilson, North Carolina, where he became mayor and was elected North Carolina Attorney General, serving from 1877 to 1885. In May 1868 he married Miss Sallie Dortch, but they had no children; Sallie died in 1916.
