Example Input: Question: Who was the president of Uptown Records when Mary J. Blige worked for the label as a backing vocalist? Passage:American singer and songwriter Mary J. Blige began her career as a backing vocalist for Uptown Records in the early 1990s. She has released 13 studio albums, eight of which have individually achieved worldwide multi-platinum status. The Queen of Hip-Hop Soul and Queen of R&B (publications often refer to her as both honorific titles), Mary J. Blige is uniquely credited as the first singer to release an album singing over hip-hop beats, which created the genre "hip hop soul" which fuses elements of soul, R&B and gospel style vocals over hip hop beats. Blige's genre-changing sound, in many ways, changed and shaped the sound for modern day R&B and blue-eyed soul artists. In September 1999, Rolling Stone bestowed her first album, What's the 411? (1992), as "genre-creating". Her discography consists of 14 top 10 Billboard 200 studio albums, two live albums, two remix albums and over eighty singlesincluding more than 20 as a featured artist. In 2009, Billboard magazine ranked Blige as the most successful female R&B/hip-hop artist of the past 25 years. In March 2017, Billboard magazine ranked her 2006 song "Be Without You" as the most successful R&B/hip-hop song of all time, as it spent an unparalleled 75 weeks on the Hot R&B/Hip-Hop Songs chart, 15 of those weeks at number one. In 2011, VH1 ranked Blige as the 80th greatest artist of all time. Moreover, she was ranked 100th on the list of "100 Greatest Singers of All Time" by Rolling Stone magazine. In 2012, VH1 ranked Blige ninth among "The 100 Greatest Woman in Music" listing.

Example Input: Question: How many soldiers did Britain send to World War I the year Roebuck arrived on the Western Front? Passage:As a boy, Roebuck worked as a trammer and after being sentenced to one month's imprisonment for stealing a watch in 1904, he enlisted in the York and Lancaster Regiment. Over the next seven years, he was stationed in India and Ireland and was promoted to lance corporal, but was demoted back to private in 1910 for "misconduct". He married in 1908 and had two children. Roebuck was discharged into the reserves in 1912 and likely returned to work as a miner prior to becoming a professional footballer in 1913. After Britain's entry into the First World War in August 1914, he was called up by the York and Lancaster Regiment and arrived on the Western Front in September 1914. On 18 October 1914, Roebuck recorded as "presumed dead" after an attack near Beaucamps-Ligny during the Race to the Sea. His death was confirmed by two comrades in January 1915. Roebuck is commemorated on the Ploegsteert Memorial to the Missing.

Example Input: Question: Who was the sponsor of the team Mirallas joined in 2012 for a reported fee of 6 million? Passage:In August 2012, Mirallas joined Premier League club Everton for a reported fee of 6 million. He made his debut as a second-half substitute during a 31 league win over Aston Villa at Villa Park in which he had a headed goal disallowed due to it being ruled offside. In his first start four days later, Mirallas scored twice and provided two assists as Everton won 50 against Leyton Orient in the second round of the League Cup. He scored his first league goal on 22 September 2012, in a 30 away win against Swansea City after heading in his initial effort which rebounded off the underside of the bar. Mirallas suffered a number of injuries which limited his number of appearances during the middle part of the season. He made a number of brief cameos, notably against Tottenham Hotspur in December. Mirallas' next goal came against Oldham Athletic in a 31 win on 26 February 2013 in the fifth round of the FA Cup. He then scored again, scoring his second league goal of the season against Reading in a 31 win on 2 March 2013. He scored his first brace in David Moyes' last home game in charge of Everton in a 20 win against West Ham United.
