Teacher: Now, understand the problem? Solve this instance: Question: How many groups played in the Festival? Passage 1:In February 2009, the band toured Europe; a number of the U.K. dates were part of a package tour sponsored by Metal Hammer dubbed "Defenders of the Faith" featuring Dimmu Borgir as co-headliners. The group then toured Australia through March as part of the Soundwave Festival, which was headlined by Nine Inch Nails and Alice in Chains. In April 2009, the group began a headlining North American tour, sponsored by No Fear Energy. The leg began in Phoenix, Arizona and wrapped up mid-May in North Myrtle Beach, South Carolina. In July 2009, during a European summer tour, guitarist Mark Morton exited the tour prior to the final six dates as he and his wife were expecting their first child. Morton was replaced by Buz McGrath of Unearth for the remaining summer dates, and Doc Coyle of God Forbid for.the first three weeks of a fall North American leg. Morton eventually rejoined the group in October in Tampa, Florida.
 Passage 2:Müller began his career with Erzgebirge Aue, and made his debut in the 2. Bundesliga in April 2008, replacing Florian Heller in a 0–0 home draw with 1. FC Kaiserslautern. He left Aue in January 2009 to join Hallescher FC of the Regionalliga Nord, where he spent two and a half seasons, being released in June 2011 after injury had restricted him to just eight appearances in the previous season. He subsequently joined SV Babelsberg 03 of the 3. Liga, for whom he scored 12 goals in the 2011–12 season. After Babelsberg were relegated in the 2012–13 season, he left to sign for Wormatia Worms, where he spent six months before joining Kickers Offenbach.
 Passage 3:In the Middle Ages Cilthriew was one of the townships in Kerry. The township is also referred to as Kilroith or Kilroyth. Richard Williams makes the claim that Cilthriew and the neighbouring house of Brynllywarch (which was also a township) were in the ownership of the Pugh (ap Hugh) family from at least 1500. A William Pugh of Kilroith is mentioned in 1632, when he purchased from Ann Foxe, widow of Somerset Foxe lands in Kilroith including Maes y Deynant William Pugh of ‘‘Kilthrew’’ was the Sheriff of Montgomeryshire in 1767 and his son William, who was also Sheriff of Montgomeryshire in 1813, became a very successful attorney and purchased the Caer Howell estate in Montgomery. His son was the notable William Pugh, an entrepreneur, who did much to develop trade and infrastructure in the Montgomeryshire Severn valley. He paid for the final extension of the Montgomery Canal from Berriew to Newtown, and for various road building schemes including a road from Abermule along the Mule valley. In Newtown he encouraged the growth of the textile industry and was responsible for the Flannel exchange, designed by Thomas Penson. In 1828 he sold the Caer Howell estate, using the proceeds to develop Brynllywarch. For this work he may have employed T G Newnham and J W Poundley as his architects and surveyors. His schemes were over ambitious and in June 1835 he fled to Caen in Normandy to escape his creditors. This resulted in the Brynllywarch and Cilthriew estates, which then consisted of 27 farms, being sold in 1839 to Richard Leyland (Bullin), a very wealthy banker from Liverpool. Leyland was to give these estates, together with the Leighton Hall Estates to his nephew John Naylor in 1846. The very detailed survey of the estates purchased by Leyland and later John Naylor, drawn up by J W Poundley, is now in the National Library of Wales. John Naylor died on13th July 1889 and the estates continued in the Naylor family ownership until about 1930, when the various farms including Cilthriew were sold.
