Q: Question: What materials are used as fuel in the type of furnace first used in the Weald to produce cast iron? Passage:Sir Francis Pettit Smith of Kent invented the screw propeller. Faversham Oyster Fishery is the oldest company in the world. Maidenhead Railway Bridge is known for its flat arch, built in 1839 with 39-metre spans. The Wealden iron industry in the Weald was the site of the first blast furnace in Britain in 1491, and produced much of Britain's cast iron until the 1770s. Portsmouth Block Mills were the site of the world's first metal machine tools, built for the manufacture of wooden pulleys, invented by Henry Maudslay, and the site of the world's first industrial assembly line in 1803. South Foreland Lighthouse on 8 December 1858 was the world's first lighthouse with electric light, with the first type of industrial electrical generator made by Frederick Hale Holmes, from work he had carried out with Floris Nollet of Belgium, and 36 permanent magnets. By 1880, of the ten lighthouses with electric light, five were in the UK. From the lighthouse in 1899, the first international radio broadcast to France was made. Zénobe Gramme of Belgium made a much better design in 1870 with self-excitation of magnets, and the first modern dynamo. North Foreland Lighthouse was the UK's last-manned lighthouse until 1998.

Q: Question: Were both of the films that Davis won Emmys for animated movies? Passage:Davis won Emmys in 1990 for Beauty and the Beast and 1995 for SeaQuest DSV. He wrote scores mostly for television series up until 1995, in which he wrote a few of the cues for the animated Disney motion picture A Goofy Movie. He continued to score television series until the two then young directors, the Wachowskis, hired him to score their neo-noir film Bound. It was reasonably successful at the box office. Bound was the film which led Davis into becoming the composer for the entire Matrix trilogy. Subsequently, Davis has composed scores for films such as Jurassic Park III (recommended to the filmmakers by John Williams, the composer of the scores for the first two films in the series), House on Haunted Hill, Behind Enemy Lines, and The Unsaid. In 2004, he produced the music score for the BBC science fiction documentary series Space Odyssey: Voyage to the Planets, released as Voyage to the Planets and Beyond in the United States.

Q: Question: What was the amount of sales for the album? Passage:A Thorn for Every Heart was started in early 2003 by Joel Ryan Holt (guitar) and Aaron Peck (drums). The original line-up of Holt, Peck, Kelvin Cruz (lead vocals), Jeff Harber (guitar, keys, backing vocals), Justin Powell (bass), and Joy Welling (violin) independently released their debut EP, Silence Is Golden, in late 2003. The EP gained them internet exposure and created an underground following, leading to talks of a record deal with Interscope. Due to musical differences, Holt (guitar/band co-founder) and ATFEH parted ways, and long-time friend Phil Nguyen joined the band in Holt's place. In support of the EP, ATFEH embarked on their first nationwide tour in 2004, during which Welling (violin) parted ways with the band due to personal differences. The band never replaced the violinist or added any other full-time instruments to the group's sound. ATFEH recorded their first full-length album, Things Aren't So Beautiful Now, with producer Shawn Sullivan (Bleeding Through, Reel Big Fish) in the summer of 2004. The album, featuring five reworked songs from the EP and five new songs, was released on October 19, 2004, through Interscope's subsidiary, Kickball Records. After recording the album, Peck (drums/band co-founder) also parted ways with the band, leaving the permanent drummer position open for a year afterward.
