Example Input: Question: Is the political party that held a Second Congress in Brussels still active? Passage:Yakov Hanecki was born in Warsaw, then in the Russian Empire, the son of Stanislav von Fürstenberg, a beer manufacturer of German descent, who had adopted Poland as his homeland. In 1896 he joined the Social Democracy of the Kingdom of Poland (SDKP - later the Social Democracy of the Kingdom of Poland and Lithuania (SDKPiL)) led by Rosa Luxemburg and her lover, Leo Jogiches. He moved to Germany in 1901 and studied in rapid succession at Berlin, Heidelberg, and Zurich universities. From 1902, he was a professional revolutionary, normally based in Cracow, under Austrian rule, organising the transport of illegal literature across the Russian border. In August 1903, as a member of the Main Administration of the SDKPiL, he was one of two Polish delegates to the Second Congress of the Russian Social Democratic Labour Party (RSDLP) in Brussels. The Congress later adjourned to London, under pressure from the Belgian police, and there the RSDLP split into its Bolshevik and Menshevik factions, but Hanecki and the other Polish delegate, Adolf Warski, did not make the journey to London, having failed to agree terms on which the RSDLP and SDKPiL could collaborate.

Example Input: Question: In city was the person who wrote  "a perfect society has no government, but only an administration, no laws, but only obligations, no punishment, but means of correction." born? Passage:Several German socialists of this period also exhibited anarchist tendencies. The young Wilhelm Weitling, influenced by both Proudhon and Louis Auguste Blanqui, once wrote that "a perfect society has no government, but only an administration, no laws, but only obligations, no punishment, but means of correction." Moses Hess was also an anarchist until around 1844, disseminating Proudhon's theories in Germany, but would go on to write the anti-anarchist pamphlet Die letzte Philosophie. Karl Grün, well known for his role in the disputes between Marx and Proudhon, held a view Nettlau would liken to communist anarchism while still living in Cologne and then left for Paris, where he became a disciple of Proudhon. Wilhelm Marr, born in Hamburg but primarily active in the Young Germany clubs in Switzerland, edited several antiauthoritarian periodicals. In his book on anarchism Anarchie oder Autorität, he comes to the conclusion that liberty is found only in anarchy.
