Example Input: Question: Where was the founder of the Quakers born? Passage:The design of the meeting house is unusual, having swayed away from the designs of traditional Quaker meeting houses. It was a result of the reunification of the two groups of Quakers that had initially separated from a schism in 1827, where two thirds of Quakers abandoned the philosophies of their founder, George Fox, and instead turned to the ideals taught by Long Island preacher, Elias Hicks. By 1926, when it was time to construct a new meeting house in Poughkeepsie, the number of local “Hicksite” Quakers was diminishing, so many had joined the Orthodox Quakers. Alfred Bussel, a New York City architect, was chosen to design a meeting house that appealed to all members. Since he had studied at Haverford College, a Quaker school, Bussell was very familiar with the Society of Friends traditions. One branch had suggested a church-like structure with steeple, organ, and stained-glass windows, while the other wanted a more traditional style meeting house, i.e. evoking simplicity, equality, community, and peace. The design therefore was a unity between the two branches, a sign of what was to come with the official reunification in the 1950s. The result is a simple, colonial revival building without stained-glass or any sort of liturgical ornamentation or symbols, as per Quaker tradition, but had a single front door (Quaker meeting houses had separate entrances for men and women) and an interior layout akin to a church; a central aisle with rows of pews on either side all facing the front of the building.

Example Input: Question: Where was Schunk's conductor for his 1986 tenor solo performance born? Passage:From 1979 onwards, he worked as a freelance singer, performing internationally. He appeared at both the Hamburg State Opera and the Vienna State Opera in 1981 as the Emperor in Die Frau ohne Schatten by Richard Strauss. In 1983, he appeared as Max in Weber's Der Freischütz at the Bregenz Festival. The same year, he made his U.S. debut as Erik at the Lyric Opera of Chicago. In 1984 he took part in the Hamburg State Opera's tour of Japan. In 1986 he appeared as Florestan in Beethoven's Fidelio at the Metropolitan Opera, opposite Hildegard Behrens in the title role, returning in 1989 as Siegmund and in 1990 as the Emperor, a role which he had also performed for his 1987 debut at the Royal Opera House. In 1996, he appeared as Loge in Wagner's Das Rheingold at the Opéra de Marseille. In addition to his opera activities, Schunk has also performed successfully in concerts. He recorded the tenor solo in Beethoven's Ninth Symphony in 1986, conducted by Georg Solti with the Chicago Symphony Orchestra & Chorus, alongside Jessye Norman, Reinhild Runkel and Hans Sotin.

Example Input: Question: How many bands competed in the Union Grove Fiddler's Convention competition against John Herald and his band? Passage:In 1958, Herald formed The Greenbriar Boys, along with Bob Yellin (banjo) and Paul Prestopino (mandolin). The following year, Eric Weissberg (mandolin and fiddle), replaced Prestopino, and Weissberg was soon replaced by Ralph Rinzler (mandolin) to form their most successful combination. Herald was lead guitarist and vocalist. The trio often played the Greenwich Village scene, but were notable enough to be the first Northern group to win the likes of the Union Grove Fiddler's Convention competition, where Yellin also took top honors for banjo. Shortly after backing Joan Baez on her second LP, The Greenbriar Boys were signed to Vanguard Records, for whom they released three records. In 1969, Linda Ronstadt recorded Herald's "High Muddy Water." Two years previously, she had recreated his vocal of Mike Nesmith's "Different Drum," which became a hit for her band the Stone Poneys.
