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 singles—including 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: Who won the award for which Beyonce was nominated for due to Polachek's song "No Angel"? Passage:In 2010, she joined Jorge Elbrecht of Brooklyn-based Violens to record a "sgin" of Justin Bieber's "Never Let You Go": "We went on YouTube to find a video among the highest ranks of hits, and came across 'Never Let You Go'. We went on to make what we call a 'sgin' (anagram of the word 'sing')—an original song written specifically to synch into someone else's video on mute". Caroline shot and directed video for Violens' "It Couldn't Be Perceived". Polachek and Elbrecht collaborated again in 2014 on two singles, "I.V. Aided Dreams (feat. Caroline Polachek)" and "Full Mental Erase (feat. Caroline Polachek)". In 2012, she sang with Ice Choir (solo project of Kurt Feldman of The Pains of Being Pure at Heart) on the song "Everything Is Spoilt by Use" and directed/edited its official video. Caroline contributed vocals to Blood Orange's "Chamakay" (2013), collaborating with Blood Orange again on "Holy Will" (2018). In late 2013, Polachek wrote and produced "No Angel", which was featured on Beyoncé's critically acclaimed fifth studio album, Beyoncé. Thanks to this song, at the 57th Annual Grammy Awards, she received a Grammy Award nomination for Album of the Year. Polachek then collaborated with PC Music's, Danny L Harle in early 2016 on the single "Ashes of Love". Polachek collaborated with felicita throughout his album "Hej!" (PC Music 2018) including an arrangement of the Polish traditional song "Byl Sobie Krol" (released under the title "Marzipan"), and with Charli XCX on Pop 2 (2017) on tracks "Tears (feat. Caroline Polachek)" and "Delicious (feat. Tommy Cash).

Example Input: Question: How old was Andrew Yarranton when he visited Dresden? Passage:The first production of tinplate was probably in Bohemia, from where the trade spread to Saxony, and was well-established there by the 1660s. Andrew Yarranton and Ambrose Crowley (a Stourbridge blacksmith and father of the more famous Sir Ambrose) visited Dresden in 1667 and found out how it was made. In doing so, they were sponsored by various local ironmasters and people connected with the project to make the river Stour navigable. In Saxony, the plates were forged, but when they conducted experiments on their return to England, they tried rolling the iron. This led to the ironmasters Philip Foley and Joshua Newborough (two of the sponsors) in 1670 erecting a new mill, Wolverley Lower Mill (or forge). This contained three shops, one being a slitting mill (which would serve as a rolling mill), and the others were forges. In 1678 one of these was making frying pans and the other drawing out blooms made in finery forges elsewhere. It is likely that the intention was to roll the plates and then finish them under a hammer, but the plan was frustrated by one William Chamberlaine renewing a patent granted to him and Dud Dudley in 1662.
