Question: Did the self-titled album by the co-writer of "Sacred Ground" have more than ten songs? Passage 1:In addition to her club tour and many radio interviews, Simpson has made in-store appearances at Wal-Mart to meet with fans, and she has a number of television appearances planned for the weeks prior to and surrounding the album's release on April 22: on Nickelodeon's Kids Choice Awards on March 29, Total Request Live on April 17 (where she gave an interview and performed "Little Miss Obsessive"), the Today show on April 18 (where she gave an interview and performed "Little Miss Obsessive", along with her 2004 song from her debut album Autobiography, "Pieces of Me"), Dance on Sunset on April 20 (performing "Little Miss Obsessive"), The Tonight Show with Jay Leno on April 21 (where she performed "Little Miss Obsessive"), Dancing with the Stars on April 22 (where she performed "Boys"), The Ellen DeGeneres Show on April 24 (where she gave an interview and performed "Little Miss Obsessive"), and Jimmy Kimmel Live! on April 24 (where she performed "Little Miss Obsessive"). She subsequently went to Europe for more promotion, performing "Outta My Head" on television shows in the United Kingdom and Germany. In connection with the album release, clothing retailer Wet Seal launched a collection of tops designed by Simpson on April 22. According to Simpson, her inspirations for Bittersweet World were reflected in the clothing line. Wet Seal also planned to sell Bittersweet World in its stores and on its website, and planned to hold a contest for which the grand prize was to include a trip to meet Simpson and attend one of the concerts on her planned tour. Simpson's 12 date summer tour was subsequently cancelled. OK! Magazine reported on May 31 that Simpson cancelled her summer tour due to her pregnancy. On July 4, Simpson was scheduled to perform for The TODAY Show's Summer Concert Series, but that performance was also cancelled.
 Passage 2:Norman Stewart Mitchell-Innes was born in Calcutta on 7 September 1914, where his father was a businessman of Scottish descent. Both his father, also named Norman, and his grandfather, Gilbert, were keen golfers. The former was the All India Amateur Golf Champion in 1893 and 1894, while the latter captained Prestwick Golf Club. He moved to England with his family at the age of five to live in Minehead, Somerset, and gained a scholarship to Sedbergh School based in Cumbria. At Sedbergh he developed quickly as a cricketer, first playing for the school's first team aged 15. The subsequent year, he scored 302 not out in a house match in one afternoon. In the summer of 1931, after scoring two half-centuries for Sedbergh against Durham School and Stonyhurst College, Mitchell-Innes was called up to play for Somerset County Cricket Club in a County Championship match against Warwickshire. He had to travel down from Scotland by overnight train for the fixture at the County Ground, Taunton. He took two wickets, and scored 23 runs in the match, which was drawn.
 Passage 3:Sacred Ground, the band's second album, came out in 1992. This album was McBride & the Ride's most successful, with all three of its singles reaching Top 5 on the country charts: "Sacred Ground" at number 2, followed by "Going Out of My Mind" (which McBride co-wrote with Kostas) and "Just One Night," both at number 5. "Sacred Ground" was co-written by Kix Brooks, who had previously released the song in 1989 from his self-titled debut album for Capitol Records before joining Ronnie Dunn to form Brooks & Dunn in 1991. In 1992, McBride & the Ride received a Best New Vocal Group or Duo nomination from the Country Music Association and Vocal Group of the Year nomination from the Academy of Country Music. More than four years after its release, Sacred Ground was certified gold by the Recording Industry Association of America for shipping 500,000 copies. Despite these sales, McBride remarked that the band still nearly lost its recording contract, due to other artists on the label selling even more strongly.

Question: How many years had the Ballet Russe de Monte Carlo been doing performances the year that Rudenko signed up with them? Passage 1:In 1938 Rudenko was signed up to the Ballet Russe de Monte Carlo, where, at 17, she was their youngest soloist. Her stage name was Lubov Roudenko, and she was also popularly known as "Spitfire Lu-Lu." She had a can-can sequence in the 1938 ballet Gaîté Parisienne choreographed specially for her by Léonide Massine. She would later reprise this role in the 1941 Oscar-nominated short film The Gay Parisian. Whilst with the Ballet Russes, Rudenko was the subject of several drawings by Henri Matisse in 1939. Four of his portrait sketches of her are now in the Fogg Museum. Matisse also made a drawing of Rudenko in the ballet  Rouge et Noir. While on tour with the Ballet Russe, Rudenko performed the role of the Cowgirl in the 1942 ballet Rodeo until the tour reached New York and Agnes de Mille, the original choreographer, reclaimed the role for herself. Disappointed by this, Rudenko quit the Ballet Russes, and took a better-paid job performing in a Broadway production of The Merry Widow. This production launched at the Majestic Theatre on 4 August 1943, with Rudenko and James Starbuck leading the character dances, including a comic polka and a can-can number. After this, Rudenko played Grisette in Nellie Bly, a short-lived 1946 musical based on the life of Nellie Bly, and then became lead dancer for the 1946-49 Broadway production of Annie Get Your Gun, but following a knee injury, decided to pursue a career in fashion design. She continued performing until 1951, appearing in the 1950-51 Olsen and Johnson revue Pardon our French.
 Passage 2:Bhutia has had limited opportunities in playing overseas. On 30 September 1999, he travelled overseas to play for Bury in Greater Manchester, England. He became only the second Indian footballer to play professionally in Europe after Mohammed Salim. By penning a three-year contract he also became the first Indian footballer to sign for a European club. This followed unsuccessful trials for Bhutia with Fulham, West Bromwich Albion and Aston Villa. He had difficulty obtaining a visa and could not make his debut, until 3 October 1999 against Cardiff City. In that match, he came on as a substitute for Ian Lawson and played a part in Bury's second goal, which was scored by Darren Bullock after Bhutia's volley was deflected into his path. On 15 April 2000, he scored his first goal in the English league in the game against Chesterfield. A recurring knee injury limited him to only three games in his final season at Bury, and he was released after the club was placed in administration. His final appearance was a 3–0 defeat to Swindon Town on 27 August 2001.
 Passage 3:Of the 62 flying fox species evaluated by the IUCN as of 2018, 3 are considered critically endangered: the Aru flying fox, Livingstone's fruit bat, and the Vanikoro flying fox. Another 7 species are listed as endangered; 20 are listed as vulnerable, 6 as near threatened, 14 as least concern, and 8 as data deficient. A further 4 are listed as extinct: the dusky flying fox, the large Palau flying fox, the small Mauritian flying fox, and the Guam flying fox. Over half of the species are threatened today with extinction, and in particular in the Pacific, a number of species have died out as a result of hunting, deforestation, and predation by invasive species. Six flying fox species are believed to have gone extinct from 1864 to 2014: the Guam, large Palau, small Mauritian, dusky, large Samoan, and the small Samoan flying foxes.

Question: Where were the two men who created the "iron law of wages" from? Passage 1:Smith assumed that workers could be paid as low as was necessary for their survival, which was later transformed by David Ricardo and Thomas Robert Malthus into the "iron law of wages". His main emphasis was on the benefit of free internal and international trade, which he thought could increase wealth through specialisation in production. He also opposed restrictive trade preferences, state grants of monopolies and employers' organisations and trade unions. Government should be limited to defence, public works and the administration of justice, financed by taxes based on income. Smith was one of the progenitors of the idea, which was long central to classical liberalism and has resurfaced in the globalisation literature of the later 20th and early 21st centuries, that free trade promotes peace. Smith's economics was carried into practice in the 19th century with the lowering of tariffs in the 1820s, the repeal of the Poor Relief Act that had restricted the mobility of labour in 1834 and the end of the rule of the East India Company over India in 1858.
 Passage 2:The first mention of modern Hägglingen is in 1036 when Count Ulrich von Lenzburg granted the church and farm of Hekelingen to Beromünster. In the acknowledgments of Emperor Henry III in 1045, the village of Hackelingen was mentioned. Frederick I Barbarossa acknowledged the grants to the village in 1173. The Vogtei (bailiwick) went from the Lenzburg family to the Kyburgs and then in 1273 to the Lords of Hallwyl. The high court rights were exercised by the Habsburgs until the Swiss conquered the Aargau in 1415. It was not until 1425 that Hägglingen, which was claimed by Lucerne, came under the authority of the entire Confederacy. It was first assigned to the district court of Wohlenschwil before it became an independent municipality from 1435-1712.
 Passage 3:Hans Klemm's first light aircraft was the Daimler L15 and the L20 had much in common with it. Both were cantilever monoplanes with twin open, tandem cockpits and engines of very low power. The L20's low wing distinguished it from its predecessor and had the advantage of providing a low centre of gravity and better view during the landing approach as well as better protection for occupants in case of crash landings. The low-set wing also allowed a shorter undercarriage on the L20, which was otherwise like that of the L15 with the wheels independently mounted on pairs of centrally hinged V-struts and with vertical shock absorbing legs to the wing underside. Wheels were sometimes replaced by floats. Intended from the start for serial production, the L20's structure was simplified, with a pentagonal cross-section fuselage lacking the L15's rounded upper and lower surfaces. The fuselage was wooden framed with canvas covering. The overall strength of the structure, which had a safety factor of 12, was emphasised.
