Example Input: Question: Who won the Grammy Award for Best Male? Passage:During 1993 and 1994, Neville expanded his repertoire as a recording artist and ventured into making country music. In 1993, Neville released The Grand Tour on A&M Records. The Grand Tour was a No.1 song for country music legend George Jones in 1974 and while Neville's version only peaked at No.38 on the Billboard country singles chart, it was highly acclaimed by fans and critics, resulting in a nomination for the Grammy Award for Best Male Country Vocal Performance at the 36th Annual Grammy Awards in 1994. Neville's next country music project involved appearing on Rhythm, Country and Blues, an album of duets featuring R&B and Country artists performing renditions of classic country and R&B songs. Neville recorded a version of I Fall to Pieces, a major crossover hit for Patsy Cline originally released in 1961, with Trisha Yearwood that resulted in Neville and Yearwood winning the Grammy Award for Best Country Collaboration with Vocals at the 37th Annual Grammy Awards. As a result, Neville became one of the only African American recording artists to win a Grammy within the Country genre.

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: What years did Baron Lyell's son serve as a member of parliament? Passage:Baron Lyell, of Kinnordy in the County of Forfar, was a title in the Peerage of the United Kingdom. It was created in 1914 for the Scottish Liberal politician Sir Leonard Lyell, 1st Baronet. He had already been created a baronet, of Kinnordy in the County of Forfar, in 1894. As his son Charles, a Liberal Member of Parliament, died on 18 October 1918 of pneumonia while serving as Assistant Military Attaché to the USA, he was succeeded by his grandson, the second Baron. He was posthumously awarded the Victoria Cross for his actions in North Africa during the Second World War. He was succeeded in the titles by his son, the third Baron, in 1943. He was one of the ninety-two elected hereditary peers that remain in the House of Lords after the passing of the House of Lords Act 1999, and sat on the Conservative benches. The titles became extinct on his death in 2017.
