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: In which country was Sir Anthony Hoskins a naval officer? Passage:Admiral Sir Anthony Hiley Hoskins, (1 September 1828 – 21 June 1901) was a Royal Navy officer. As a junior officer, he took part in the Cape Frontier War of 1851 and then saw action at the Battle of Canton in December 1857 and the Battle of Taku Forts in May 1858 during Second Opium War. Once promoted to flag officer rank, he acted as Second-in-Command of the Fleet at the bombardment of Alexandria in July 1882 during the Anglo-Egyptian War. He went on to be First Naval Lord in September 1891 but in that role took a relaxed view of the size of the Fleet and did not see the need for a large shipbuilding effort on the scale envisaged by some of his colleagues, such as Admiral Sir Frederick Richards and Admiral Sir John Fisher who were concerned about French and German naval expansion.
