Input: Consider Input: Question: How long did the king who was painted by Jan Matejko rule Poland? Passage:Modern history accepts this gateway as one of three constructed by Yaroslav the Wise. The golden gates were built in 1017-1024 (6545 by the Byzantine calendar) at about the same time the Saint Sophia Cathedral was erected. Mentions of an older construction, such as the one presented on a painting by Jan Matejko of king Bolesaw I of Poland striking the Golden Gate with his sword during the intervention in the Kievan succession crisis in 1018, it is now regarded a legend. Originally named simply the Southern Gate, it was one of the three main entrances to the walled city, along with the Ladski and Zhydivski (Polish and Jewish) Gates. The last two have not survived. The stone fortifications stretched for only 3.5 km. The fortification of the Old Kyiv (Upper City) stretched from the Southern Gates down to what is now Independence Square and where the Lechitic Gate was located. From there, the moat followed what is now Kostyol Street, skirting St. Michael's Monastery and continuing along today's Zhytomyr Street toward the Jewish Gates (at ). From there, the fortification stretched what is now Yaroslaviv Val ("Yaroslav's Rampart") Street back to the Southern Gate.

Input: Consider 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.
