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.

Question: What was the length of the reign of the monarch who founded the dockyard? Passage:In medieval times the part of Gillingham known as Grange was a limb of the Cinque Ports and the maritime importance of the area continued until the late 1940s. Indeed, a large part of Chatham Dockyard lay within Gillingham: the dockyard started in Gillingham and, until the day it was closed in 1984, two-thirds of the then modern-day dockyard lay within the boundaries of Gillingham. The dockyard was founded by Queen Elizabeth I on the site of the present gun wharf, the establishment being transferred to the present site about 1622. In 1667 a Dutch fleet sailed up the River Medway and, having landed at Queenborough on the Isle of Sheppey and laying siege to the fort at Sheerness, invaded Gillingham in what became known as the raid on the Medway. The Dutch eventually retreated, but the incident caused great humiliation to the Royal Navy.
