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: How many people currently live in the city that was captured in 1630 by a Persian army? Passage 1:Gradually Clayburgh shifted into being more of a supporting character actress in the 90s, taking on roles as diverse as an antagonistic judge in Trial: The Price of Passion (1992) and the interfering wife of Alan Alda's character in Whispers in the Dark (1992). After appearing in Ben Gazzara's Beyond the Ocean (1990), which was shot in Bali, and the unreleased Pretty Hattie's Baby (1991), she became typecast as an attractive maternal figure: she was the long-missing matriarch in Rich in Love (1992), a wheelchair-bound mom in Firestorm: 72 Hours in Oakland (1993) and Eric Stoltz's single mother in Naked in New York (1993). A review in People magazine felt Clayburgh "[did] her best as the footloose mother" in Rich in Love, while Roger Ebert praised her casting in Naked in New York as "exactly on target". She also played Kitty Menendez who was murdered by her sons in Honor Thy Father and Mother: The True Story of the Menendez Murders (1993), a role which Variety perceived to be "incomplete, but that has more to do with the script than Clayburgh’s performance." She continued to play concerned, protective mothers in For the Love of Nancy (1994), The Face on the Milk Carton (1995), Going All the Way (1997), Fools Rush In (1997), When Innocence Is Lost (1997) and Sins of the Mind (1997), and was in "good form" as the forceful, pushy stage mother in Crowned and Dangerous (1997).
 Passage 2:A son of Daud Khan, a Georgian prince and convert to Islam, by a concubine, he was born Khosro Mirza and brought up Muslim at the Persian court by eunuchs alongside young slave recruits. An intelligent and resolute in his decisions, he soon attracted the attention of Shah Abbas I of Safavid who appointed him, in 1618, a darugha (prefect) of the capital Isfahan. From 1625 to 1626, he took part in suppression of the Georgian opposition: he commanded a right flank at the victorious Battle of Marabda and saved part of the Persian troops from a complete disaster at the Battle of Ksani. In 1626, Khosro Mirza was recalled from Georgia and appointed the commander of the Shah's élite gholam corps (qollar-aghasi) three years later. In 1629, Abbas, lying on a deathbed, urged him to protect a grandson and heir Sam Mirza, the future Shah Safi, whom Khosro served faithfully. In 1630, he led a Persian army which defeated the Ottoman forces and captured Baghdad. In the early 1630s, he took part in sidelining and destruction of the Undiladze family, also of Georgian origin, who had dominated the Safavid court for years. Afterwards, he was sent to suppress the opposition of Georgians who had managed to unite the eastern regions of Kartli and Kakheti under Teimuraz I for a brief period of 1630-1633. Teimuraz was joined by a surviving Undiladze, Daud Khan. For his loyalty, Shah Safi appointed him as the new vali of Kartli, and granted him the name of Rostam Khan (Rostom, როსტომი, in Georgian transliteration). Rostom then came to Georgia with a large Persian army commanded by his fellow Georgian Rustam Khan. He soon took control of Kartli and garrisoned all major fortresses with Persian forces, bringing them, however, under his tight control. His willingness to cooperate with his suzerain won for Kartli a larger degree of autonomy. A period of relative peace and prosperity ensued, with the cities and towns being revived, many deserted areas repopulated and commerce flourished. Although Muslim, Rostom helped to restore a major Georgian Orthodox cathedral of Living Pillar (Svetitskhoveli) at Mtskheta, and patronised Christian culture. However, Islam and Persian habits predominated at his court. He ruthlessly crushed an opposition of local nobles, putting to death the catholicos Eudemus I of Georgia, and invaded, in 1648, Kakheti, forcing Teimuraz to flee to Imereti (western Georgia).
 Passage 3:Ferrary was the son of the Duke and Duchess of Galliera. His father, Raffaele de Ferrari, came from an ancient and rich family of Genovese bankers and was a wealthy businessman made Duke of Galliera in Genoa by Pope Gregory XVI, and Prince de Lucedio by Victor-Emmanuel II, King of Italy. Raffaele de Ferrari was co-founder of the Crédit Mobilier with the Péreire brothers, rivals of the Rothschilds, who financed many of the major construction projects of the second half of the 19th century: railroads in Austria, Latin America, Portugal, upper Italy and France (the Paris-Lyon-Marseille line), the digging of the Fréjus Rail Tunnel and the Suez Canal, and the reconstruction of Paris designed by Baron Haussmann. It is said that Raffaele de Ferrari died stuck in one of his immense safes.

Question: How long is the road that runs through Carneys Point Township? Passage 1:At the time of his accession, Theophilos was obliged to wage wars against the Arabs on two fronts. Sicily was once again invaded by the Arabs, who took Palermo after a year-long siege in 831, established the Emirate of Sicily, and gradually continued to expand across the island. The defence after the invasion of Anatolia by the Abbasid Caliph Al-Ma'mun in 830 was led by the Emperor himself, but the Byzantines were defeated and lost several fortresses. In 831 Theophilos retaliated by leading a large army into Cilicia and capturing Tarsus. The Emperor returned to Constantinople in triumph, but in the autumn he was defeated in Cappadocia. Another defeat in the same province in 833 forced Theophilos to sue for peace (Theophilos offered 100,000 gold dinars and the return of 7,000 prisoners), which he obtained the next year, after the death of Al-Ma'mun.
 Passage 2:The first of CR 540 are concurrent with the entire length of Route 140, running southeast through commercial areas of Carneys Point Township from an intersection with US 130 and interchanging with I-295 and the New Jersey Turnpike/US 40 at the point US 40 splits from the New Jersey Turnpike. From the east end of Route 140, signage for CR 540 begins past US 40, with the route heading southeast on two-lane undivided Hawks Bridge Road. The road runs through residential neighborhoods before crossing the Salem River into Mannington Township. The route intersects CR 631 as it heads through forests before entering a mix of woods and farms as the road turns south and briefly becomes a divided highway at the CR 646 junction. From here, CR 540 becomes Pointers Road and runs through more agricultural areas, crossing the marshy Mannington Creek before briefly turning southeast onto Bypass Road and intersecting CR 620 and Route 45.
 Passage 3:Dudow was born in Zaribrod, Bulgaria (today Dimitrovgrad, Serbia). In 1922, he emigrated to Berlin with the intention of becoming an architect. He gave up this plan and began studying theatre in 1923, first under Emmanuel Reicher, and then, from 1925 to 1926, as a theatre studies student under Max Herrmann at the university. He worked with Leopold Jessner and Jürgen Fehling, served as a chorus member under Erwin Piscator, and was a director's assistant to Fritz Lang on the production of Metropolis. During this time, Dudow also ran a bookstore with his wife and worked as a foreign correspondent for a Bulgarian newspaper. In 1929, he visited the Soviet Union, where he met Vladimir Mayakovsky and Sergei Eisenstein in Moscow and eventually, Bertolt Brecht. After his return from the USSR, Dudow directed Brecht's theatrical piece, The Decision (Die Massnahme), and began his film directing career. He was commissioned by the left-wing, Soviet-German production company Prometheus-Film to direct a short film, Wie der Berliner Arbeiter wohnt (1929), as part of the documentary series Wie lebt der Berliner Arbeiter? Dudow's first feature, Kuhle Wampe (To Whom Does the World Belong?, 1932) was a collaboration with Brecht (who provided the script and helped finance the project), Hanns Eisler, and Ernst Ottwalt. It was banned because it was perceived as being politically subversive.
