Question: Mary Teresa Slaney (formerly Tabb, nee Decker; born August 4, 1958) is a retired American middle-distance runner. During her career, she won gold medals in the 1500 meters and 3000 meters at the 1983 World Championships, and was the world record holder in the mile, 5000 meters and 10,000 meters. In total, she set 17 official and unofficial world records, including being the first woman in history to break 4:20 for the mile. She also set 36 US national records at distances ranging from 800 meters to 10,000 meters, and has held the US record in the mile, 2000 meters and 3000 meters since the early 1980s, while her 1500 meters record stood for 32 years.

In her early teens, Decker was already recognized as a world-class runner. Unable to attend the 1972 Olympics as she was too young, the pigtailed 89 pounds (40 kg) 14-year-old nicknamed "Little Mary Decker," won international acclaim in 1973 with a win in the 800 meters at a US-Soviet meet in Minsk, beating the later Olympic silver medallist. By the end of 1972, Decker was ranked first in the United States and fourth in the world in the 800 meters. In 1973 she gained her first world record, running an indoor mile in 4:40.1. By 1974, Decker was the world Indoor record holder with 2:02.4 for 880 yards, and 2:01.8 for 800 meters. By the end of 1974, she had developed a case of the muscle condition compartment syndrome. This resulted in a series of injuries, which meant that she did not compete in the 1976 Olympics, because of stress fractures in her lower leg. In 1978 she had an operation to try to cure compartment syndrome, which kept her out of competition for a period. After recovering from surgery, she spent two seasons at the University of Colorado at Boulder on a track scholarship. In 1979, she became the second American woman (the first was Francie Larrieu) to break the 4:30 mile in American record time. Decker was the first woman to break the 4:20 barrier for the mile in 1980 when she ran it in 4:17.55. However, this time was never ratified by the IAAF. In 1981 she married fellow American distance runner Ron Tabb. The couple divorced in 1983. In 1982, under the name Mary Tabb, she ran the mile in 4:18.08, breaking the official record of 4:20.89 by the Soviet Lyudmila Veselkova This time was ratified. She did not compete for an Olympic medal due to the U.S.-led 1980 Summer Olympics boycott. She did however receive one of 461 Congressional Gold Medals created especially for the spurned athletes.

Question: Giuseppe Fortunino Francesco Verdi (Italian: [dZu'zeppe 'verdi]; 9 or 10 October 1813 - 27 January 1901) was an Italian opera composer. He was born near Busseto to a provincial family of moderate means, and developed a musical education with the help of a local patron. Verdi came to dominate the Italian opera scene after the era of Vincenzo Bellini, Gaetano Donizetti, and Gioachino Rossini, whose works significantly influenced him. By his 30s, he had become one of the pre-eminent opera composers in history.

List of compositions by Giuseppe Verdi In mid-1834, Verdi sought to acquire Provesi's former post in Busseto but without success. But with Barezzi's help he did obtain the secular post of maestro di musica. He taught, gave lessons, and conducted the Philharmonic for several months before returning to Milan in early 1835. By the following July, he obtained his certification from Lavigna. Eventually in 1835 Verdi became director of the Busseto school with a three-year contract. He married Margherita in May 1836, and by March 1837, she had given birth to their first child, Virginia Maria Luigia on 26 March 1837. Icilio Romano followed on 11 July 1838. Both the children died young, Virginia on 12 August 1838, Ilicio on 22 October 1839. In 1837, the young composer asked for Massini's assistance to stage his opera in Milan. The La Scala impresario, Bartolomeo Merelli, agreed to put on Oberto (as the reworked opera was now called, with a libretto rewritten by Temistocle Solera) in November 1839. It achieved a respectable 13 additional performances, following which Merelli offered Verdi a contract for three more works. While Verdi was working on his second opera Un giorno di regno, Margherita died of encephalitis at the age of 26. Verdi adored his wife and children and was devastated by their deaths. Un giorno, a comedy, was premiered only a few months later. It was a flop and only given the one performance. Following its failure, it is claimed Verdi vowed never to compose again, but in his Sketch he recounts how Merelli persuaded him to write a new opera. Verdi was to claim that he gradually began to work on the music for Nabucco, the libretto of which had originally been rejected by the composer Otto Nicolai: "This verse today, tomorrow that, here a note, there a whole phrase, and little by little the opera was written", he later recalled. By the autumn of 1841 it was complete, originally under the title Nabucodonosor. Well received at its first performance on 9 March 1842, Nabucco underpinned Verdi's success until his retirement from the theatre, twenty-nine operas (including some revised and updated versions) later. At its revival in La Scala for the 1842 autumn season it was given an unprecedented (and later unequalled) total of 57 performances; within three years it had reached (among other venues) Vienna, Lisbon, Barcelona, Berlin, Paris and Hamburg; in 1848 it was heard in New York, in 1850 in Buenos Aires. Porter comments that "similar accounts...could be provided to show how widely and rapidly all [Verdi's] other successful operas were disseminated."
