Example Input: Question: Which of Kuroda's contemporaries had more championships, Hosaka or Tanaka? Passage:Kuroda began his professional wrestling career in January 1993, when he was trained by Pro Wrestling Crusaders (PWC) at their dojo and made his debut on March 18, 1993 against Hideki Hosaka. PWC closed after a few months and Kuroda resumed his training at the Frontier Martial-Arts Wrestling (FMW) dojo. He made his FMW debut as a fan favorite with Masato Tanaka by losing to Dark Ranger and Masaru Toi in a tag team match on October 15. Kuroda remained in the low card for many years in the company and was usually utilized in opening matches on the card and served as a enhancement talent against higher level opponents, winning against only lesser known talent. He was often paired with fellow newcomer Tanaka in mid-card matches during the early years of his career and often wrestled Tanaka, Koji Nakagawa and Gosaku Goshogawara. Kuroda's first main event match took place on November 26, 1994, when he teamed with Atsushi Onita, Katsutoshi Niiyama and Masato Tanaka to defeat Mr. Pogo, The Gladiator, Hideki Hosaka and Hisakatsu Oya in a no ropes barbed wire street fight deathmatch. Kuroda would team with Onita, Niiyama and Tanaka in several street fights during late 1994 and early 1995. In the summer of 1995, Kuroda was entered into the Young Spirit Tournament, a round robin tournament consisting of rising rookies of the company. He would lose all of his matches in the tournament against W*ING Kanemura, Hideki Hosaka, Koji Nakagawa and Hido, while wrestling Masato Tanaka to a double knockout to gain one point in the tournament.

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 197279 ("People Need Love" to "Does Your Mother Know"), and the second including the singles from 197982 ("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 Manana". 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.
