[EX Q]: Question: How many members did the Boston Symphony Orchestra have when Lilacs for voice and orchestra was premiered by the group? Passage 1:Whitman's poem appears in the Broadway musical Street Scene (1946) which was the collaboration of composer Kurt Weill, poet and lyricist Langston Hughes, and playwright Elmer Rice. Rice adapted his 1929 Pulitzer prize-winning play of the same name for the musical. In the play, which premiered in New York City in January 1947, the poem's third stanza is recited, followed by duet, "Don't Forget The Lilac Bush", inspired by Whitman's verse. Weill received the first Tony Award for Best Original Score for this work African-American composer George T. Walker, Jr. (born 1922) set Whitman's poem in his composition Lilacs for voice and orchestra which was awarded the 1996 Pulitzer Prize for Music. The work, described as "passionate, and very American," with "a beautiful and evocative lyrical quality" using Whitman's words, was premiered by the Boston Symphony Orchestra on February 1, 1996. Composer George Crumb (born 1929) set the Death Carol in his 1979 work Apparition (1979), an eight-part song cycle for soprano and amplified piano.
 Passage 2:At the 1989 election, Buchanan successfully transferred to the newly recreated seat of Ashburton, with her replacement in Pilbara, Larry Graham, retaining that seat for Labor. The re-elected Dowding government persisted only until February 1990, when it was replaced by the Lawrence government following Dowding's forced resignation. New premier Carmen Lawrence elevated Buchanan to the ministry as Minister for Works and Services and Minister for Regional Development. She was also made assistant minister to Lawrence in her capacity as Minister for Aboriginal Affairs. However, the regional development portfolio was abolished in December 1990, and Buchanan lost her remaining portfolios in February 1991, as part of a ministerial reshuffle prompted by an internal spill motion. Jeff Carr and Gavan Troy were also removed as ministers, with Carr consequently resigning from parliament. Buchanan herself resigned to sit as an independent on 1 February 1991, before the new ministry was sworn in four days later. She consequently became the first woman in the Parliament of Western Australia to sit as an independent. Buchanan resigned due to ill health just over a year later, in March 1992, and died at the end of that month, aged 55. She had married George Maitland Buchanan in April 1957, with whom she had two daughters. Her resignation prompted a by-election in Ashburton, which was won by the Labor candidate Fred Riebeling.

[EX Q]: Question: Who was the ruler of South African mandate when it took over the South West Africa German colony? Passage 1:German Namibians () are a community of people descended from ethnic German colonists who settled in present-day Namibia. In 1883, the German trader Adolf Lüderitz bought what would become the southern coast of Namibia from Josef Frederiks II, a chief of the local Oorlam people, and founded the city of Lüderitz. The German government, eager to gain overseas possessions, annexed the territory soon after, proclaiming it German South West Africa (). Small numbers of Germans subsequently immigrated there, many coming as soldiers (), traders, diamond miners, or colonial officials. In 1915, during the course of World War I, Germany lost its colonial possessions, including South West Africa (see History of Namibia); after the war, the former German colony was administered as a South African mandate. The German settlers were allowed to remain and, until independence in 1990, German remained an official language of the territory alongside Afrikaans and English.
 Passage 2:Earle L. Reynolds (October 18, 1910 – January 11, 1998) was an anthropologist, educator, author, Quaker, and peace activist. He was sent to Hiroshima by the Atomic Energy Commission in 1951 to study the effects of the first atomic bomb on the growth and development of exposed children. His professional discoveries concerning the dangers of radiation later moved Reynolds into a life of anti-nuclear activism. In 1958 he sailed with his wife Barbara, two of his three children and a Japanese yachtsman in the Phoenix of Hiroshima, a ketch he had designed himself, into the American nuclear testing zone in the Pacific. In 1961 the family sailed to the USSR to protest Soviet nuclear testing. During the Vietnam War Reynolds and his second wife Akie sailed the Phoenix to Haiphong to deliver humanitarian and medical aid to victims of American bombing.
 Passage 3:The Anita Kerr Singers or The Jordanaires sang background on just about every Nashville hit in the late 1950s and early 1960s. After she and Al Kerr divorced, she disbanded the Nashville version of her Anita Kerr Singers and relocated to Los Angeles in August 1965 with her second husband, Swiss businessman Alex Grob, and her daughters Suzie & Kelly. She no longer wanted to just be a background singer or arranger on country songs – she wanted to do pop music, jazz and "do more orchestral writing and music that was not just country.". She hired some lawyers to get her out of her contract with RCA’s Nashville division, got a contract with Warner Bros. Records, and formed a Los Angeles version of the Anita Kerr Singers. The new group, for the next five years, would include the following personnel: alto B.J. Baker or Jackie Ward, tenor Gene Merlino or Bill Cole, baritone Bill Lee, bass Bob Tebow, and Kerr herself as soprano and arranger. The half dozen albums recorded by the Singers for Warner included a cover version of the song "All You Need Is Love" by The Beatles, and one of the LPs was exclusively devoted to the songs of composer Bert Kaempfert. Disguising the group as the Mexicali Singers, Kerr also recorded a trio of mariachi-flavored albums with musical arrangements reminiscent of the Herb Alpert & The Tijuana Brass sound. The Anita Kerr Singers won another Grammy Award for their recording of A Man And A Woman, released as a single on Warner Bros. Records.

[EX Q]: Question: Which astronomical body that the US planned to build an outpost on has a bigger mass? Passage 1:In 1642, Williams, as a well connected local man and strong Protestant, was appointed by the King with a Commission of Array. At the outbreak of what was to become the First English Civil War, this gave him responsibilities for raising an army within Monmouthshire for the King, and holding the county against opposition. He was also created a baronet (one of several Williams baronets in Wales). Having set about his allotted task he was captured by Parliamentary forces in 1643 at Highnam during the Siege of Gloucester. After his release, he set about fortifying the ruined medieval stone castle at Llangibby, beside the Caerleon to Usk road, and garrisoned it with 60 men. In 1644 he helped lead operations around Monmouth. After the town was lost to the Parliamentarians he pleaded with Prince Rupert for more men and ammunition, following which he helped lead its recapture.
 Passage 2:Mars Outpost is a concept for a human base on the planet Mars that was developed by the United States in the 1980s. The components and design were based on an earlier lunar test bed outpost. Development would go through several phases over four years, from an 'Emplacement Phase' to a 'Consolidation Phase', after which full use by its crew could commence. Components of the base would include a habitat module, pressurized rover dock/equipment lock, airlocks, and a constructed habitat. The 16 m habitat would be constructed in situ. Other technology for the base design includes a meteorological balloon, unpressurized rover, storage/work area, an area for geophysical experiments, and an area antenna. The Mars Outpost would be designed for a crew of 7 astronauts. Their main tasks would be to do research on mining of Mars and Phobos, life sciences, technology, and solar system exploration. The Office of Space Exploration did case studies that include establishing a human presence on another planet in 1988 and 1989. An objective of the Mars Evolution 1989 study was, "Emplace a permanent, largely self-sufficient outpost on the surface of Mars."
 Passage 3:The song initially gained popularity on social video sharing app TikTok and eventually entered the Billboard charts in March 2019. The song reached number 19 on the Billboard Hot Country Songs chart before the magazine disqualified it from being included on the chart on grounds that it did not fit the genre, sparking a debate on the definition of country music. Though the song was not re-entered onto the overall country charts, both the original version of the song and the remix featuring Cyrus eventually peaked at number one on the flagship Billboard chart, the Hot 100, for a record-breaking nineteen consecutive weeks. Internationally, one or more versions of "Old Town Road" have topped the national singles charts in Australia, Canada, France, Germany, Ireland, the Netherlands, New Zealand, Norway, Switzerland, and the United Kingdom; and charted within the top ten in various other markets. Furthermore, the song was awarded diamond certification by the RIAA, in October 2019, for moving ten million total units in the United States, the fastest song to be awarded diamond certification. The remix of "Old Town Road" featuring Billy Ray Cyrus has been nominated for Record of the Year and Best Pop Duo/Group Performance at the 62nd Annual Grammy Awards, with its music video receiving a nomination for Best Music Video.
