Input: Consider Input: Question: How many miles from Chattanooga, Tennessee does it take to travel to Lookout Mountain by railway? Passage:The Lookout Mountain Incline Railway is a inclined plane funicular railway leading to the top of Lookout Mountain from the historic St. Elmo neighborhood of Chattanooga, Tennessee. Passengers are transported from St. Elmo's Station at the base, to Point Park at the mountain summit, which overlooks the city and the Tennessee River. It is just a short drive to three of Chattanooga's main tourist attractions, Ruby Falls, Cavern Castle, and Rock City. The railway is approximately in length (single-track except for a short two-track passing loop at the midway point, allowing operation of two cars at one time). It has a maximum grade of 72.7%, making it one of the world's steepest passenger railways. It obtained Historic Mechanical Engineering Landmark status in 1991. The cable system for the cars was made by the Otis Elevator Company.

Input: Consider Input: Question: In which country was Luigi Guardigli born? Passage:Guardigli was born in Ravenna. At 18 he enrolled in and attended the School of Fine Arts of Ravenna. During World War II he was drafted and served from 1943 until 1946 in the Regia Marina (Italian Royal Navy) at La Spezia). After the war he returned to the School of Fine Arts, receiving his diploma in 1948. He enrolled in the School of Painting and Mosaics, also in Ravenna, graduating in 1951. From 1951 to 1955 he worked with the Gruppo mosaicisti of Ravenna and restored many mosaics. Also in 1951, at the end of November, he arrived in Paris to teach at the Ecole d'Art Italien (School of Italian Art) as an assistant to the painter Gino Severini, founder and director of the school. Together with another mosaicist, his fellow Ravennan Lino Melano, he executed mosaic works for artists including Fernand Léger, Georges Braque, Marc Chagall, Jean Bazaine, and Raoul Ubac. He collaborated also on the mosaic for the façade of the Musée national Fernand Léger in Biot (Alpes-Maritimes). In 1960 he executed, at the Colombe d'Or of Saint-Paul-de-Vence, a mosaic by the painter Georges Braque. From 1961 he had a studio in the artists' residence La Ruche at 2, passage de Dantzing in Paris, the place described by Lorenzo Viani in the book Parigi 1925 (Paris 1925), published by Fratelli Treves. In 1962, in another collaboration with Braque, he created the famous long fish tank of the Fondation Maeght in St Paul de Vence. His collaborations with many illustrious artists continued; the last was Jean-Michel Folon. Many of his personal works in painting and mosaics are in prominent private and public collections. The latter portion of his life was spent in an old people's rest home in Paris, where he died in 2008.

Input: Consider Input: Question: Where all the members of the Sex Pistols from the same part of London? Passage:The Sex Pistols evolved from the Strand, a London band formed in 1972 with working-class teenagers Steve Jones on vocals, Paul Cook on drums and Wally Nightingale on guitar. According to a later account by Jones, both he and Cook played on instruments they had stolen. Early line-ups of the Strand—sometimes known as the Swankers—also included Jim Mackin on organ and Stephen Hayes (and later, briefly, Del Noones) on bass. The band members regularly hung out at two clothing shops on the King's Road in Chelsea, London: John Krivine and Steph Raynor's Acme Attractions (where Don Letts worked as manager) and Malcolm McLaren and Vivienne Westwood's Too Fast to Live, Too Young to Die. McLaren's and Westwood's shop had opened in 1971 as Let It Rock, with a 1950s revival Teddy Boy theme. It had been renamed in 1972 to focus on another revival trend, the rocker look associated with Marlon Brando. As John Lydon later observed, "Malcolm and Vivienne were really a pair of shysters: they would sell anything to any trend that they could grab onto." The shop became a focal point of the punk rock scene, bringing together participants such as the future Sid Vicious, Marco Pirroni, Gene October, and Mark Stewart, among many others. Jordan, the wildly styled shop assistant, is credited with "pretty well single-handedly paving the punk look".
