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 what year was the commander in chief who sent Elles to investigate the first tanks born? Passage:In August 1915, after recovering from his injuries, Elles was one of three officers specially selected by General Sir William Robertson, soon to be Chief of the Imperial General Staff (CIGS), the professional head of the British Army, to liaise with troops at the front and pass the information directly to the British General Headquarters (GHQ). In January 1916, as a General Staff Officer (GSO), Elles was sent by General Sir Douglas Haig, the Commander-in-Chief (C-in-C) of the BEF on the Western Front, to investigate the first tanks or "caterpillars" being built in England. He attended the first trials of "Mother" and reported back to Haig on its success. During the summer of 1916, he was tasked to report back from the Somme, where the tanks were first used. Elles was appointed to head the Heavy Branch (the first tank units) of the Machine Gun Corps in France on 29 September 1916, with the temporary rank of colonel. His responsibilities included its advanced training and tactical employment. He also commanded the large central depot and workshops established near Bermicourt.
