Problem: Please answer a question about the following article about Frédéric Chopin:
Frédéric François Chopin (/ˈʃoʊpæn/; French pronunciation: ​[fʁe.de.ʁik fʁɑ̃.swa ʃɔ.pɛ̃]; 22 February or 1 March 1810 – 17 October 1849), born Fryderyk Franciszek Chopin,[n 1] was a Polish and French (by citizenship and birth of father) composer and a virtuoso pianist of the Romantic era, who wrote primarily for the solo piano. He gained and has maintained renown worldwide as one of the leading musicians of his era, whose "poetic genius was based on a professional technique that was without equal in his generation." Chopin was born in what was then the Duchy of Warsaw, and grew up in Warsaw, which after 1815 became part of Congress Poland. A child prodigy, he completed his musical education and composed his earlier works in Warsaw before leaving Poland at the age of 20, less than a month before the outbreak of the November 1830 Uprising.
The majority of Chopin's compositions were for what instrument?
A: solo piano
Problem: Please answer a question about the following article about Umayyad Caliphate:
Yazid died while the siege was still in progress, and the Umayyad army returned to Damascus, leaving Ibn al-Zubayr in control of Mecca. Yazid's son Muawiya II (683–84) initially succeeded him but seems to have never been recognized as caliph outside of Syria. Two factions developed within Syria: the Confederation of Qays, who supported Ibn al-Zubayr, and the Quda'a, who supported Marwan, a descendant of Umayya via Wa'il ibn Umayyah. The partisans of Marwan triumphed at a battle at Marj Rahit, near Damascus, in 684, and Marwan became caliph shortly thereafter.
Who was the son of Yazid?
A: Muawiya II
Problem: Please answer a question about the following article about Karl Popper:
Popper played a vital role in establishing the philosophy of science as a vigorous, autonomous discipline within philosophy, through his own prolific and influential works, and also through his influence on his own contemporaries and students. Popper founded in 1946 the Department of Philosophy, Logic and Scientific Method at the London School of Economics and there lectured and influenced both Imre Lakatos and Paul Feyerabend, two of the foremost philosophers of science in the next generation of philosophy of science. (Lakatos significantly modified Popper's position,:1 and Feyerabend repudiated it entirely, but the work of both is deeply influenced by Popper and engaged with many of the problems that Popper set.)
Where did Popper establish a university department for the philosophy of science in 1946?
A: London School of Economics
Problem: Please answer a question about the following article about Josip Broz Tito:
During his life and especially in the first year after his death, several places were named after Tito. Several of these places have since returned to their original names, such as Podgorica, formerly Titograd (though Podgorica's international airport is still identified by the code TGD), and Užice, formerly Titovo Užice, which reverted to its original name in 1992. Streets in Belgrade, the capital, have all reverted to their original pre–World War II and pre-communist names as well. In 2004, Antun Augustinčić's statue of Broz in his birthplace of Kumrovec was decapitated in an explosion. It was subsequently repaired. Twice in 2008, protests took place in Zagreb's Marshal Tito Square, organized by a group called Circle for the Square (Krug za Trg), with an aim to force the city government to rename it to its previous name, while a counter-protest by Citizens' Initiative Against Ustašism (Građanska inicijativa protiv ustaštva) accused the "Circle for the Square" of historical revisionism and neo-fascism. Croatian president Stjepan Mesić criticized the demonstration to change the name. In the Croatian coastal city of Opatija the main street (also its longest street) still bears the name of Marshal Tito, as do streets in numerous towns in Serbia, mostly in the country's north. One of the main streets in downtown Sarajevo is called Marshal Tito Street, and Tito's statue in a park in front of the university campus (ex. JNA barrack "Maršal Tito") in Marijin Dvor is a place where Bosnians and Sarajevans still today commemorate and pay tribute to Tito (image on the right). The largest Tito monument in the world, about 10 m (33 ft) high, is located at Tito Square (Slovene: Titov trg), the central square in Velenje, Slovenia. One of the main bridges in Slovenia's second largest city of Maribor is Tito Bridge (Titov most). The central square in Koper, the largest Slovenian port city, is as well named Tito Square.
When did Uziece revert to its original name?
A:
1992
