Example Input: Question: Are the well-known jazz and classical pianists that the quartet worked with both men? Passage:The Annex String Quartet, also known as The Annex Quartet, is a string quartet founded by violist Yunior Lopez in 2008 in Toronto, Ontario, Canada. Named after The Annex neighbourhood in downtown Toronto, the quartet began performing regularly in Toronto's many bars, coffee shops, and non-classical venues like Aroma Espresso Bar and the St. Lawrence Market. In 2010, they made their American debut alongside the Kronos Quartet at Carnegie Hall, and have since appeared in over 100 performances, recordings, and broadcasts. To date, the group's primary focus has been bridging the gap between classical and world music, which has led them to become one of the most eclectic performing ensembles in North America. They have performed, recorded, and ventured into various musical styles, and continue to work with a diverse range of artists including classical pianist, Jan Lisiecki, Cuban jazz pianist, Hilario Duran, and Canadian jazz icon, Jane Bunnett. Following multiple recording collaborations with a diverse range of artists, The Annex Quartet released their official debut album, The Roaring Twenties, in June 2013. The quartet's current work in progress is an all-Cuban album featuring famed Cuban Bolero singer, Anais Abreu. They are currently the ensemble-in-residence at Midtown Music School in Toronto and The Stratford Summer Music Festival in Stratford, Ontario.

Example Input: Question: How much did the position director of football for Newcastle United pay in 2013? Passage:On 16 June 2013, in a series of telephone interviews Kinnear claimed he had been appointed as director of football for Newcastle United. In a Talksport interview over the telephone on 17 June 2013, Kinnear claimed to have replaced someone called "Derek Lambesi" (sic) as the club's director of football, signed Dean Holdsworth at Wimbledon for £50,000 (actually £650,000), sold Robbie Earle (retired a year after Kinnear left), signed goalkeeper Tim Krul when he was previously manager (actually signed by Graeme Souness three years prior) and has been awarded the LMA Manager of the Year award three times despite only winning the award once, he also said he'd never been sacked in his life. Kinnear claimed to have signed John Hartson on a free when he in fact paid £7.5 million for the striker. He also mispronounced the names of Yohan Cabaye, Hatem Ben Arfa, Shola Ameobi and others in the Talksport interview. The appointment, a three-year contract, was confirmed by Newcastle United on 18 June. The confusion around Kinnear's appointment to the role was criticised by former club chairman Freddy Shepherd in an interview with BBC Sport. Kinnear drew criticism when the 2013 summer transfer window closed with Kinnear failing to make a single permanent signing, lone recruit Loïc Rémy having been signed on loan from Queens Park Rangers. This criticism intensified at the end of the 2014 winter transfer window with Kinnear failing again to make a permanent signing, this after the £20 million sale of midfielder Yohan Cabaye, with Luuk de Jong having been brought in on loan from Borussia Mönchengladbach.
