Input: Consider Input: Question: Did Oerter stay in Germany after he moved away from Bavaria? Passage:By the early 1890s he had moved away from Bavaria and, with his brother, was working in Duisburg. Together the brothers smuggled subversive anarchist literature into Germany from the Netherlands. Coming under increasing police pressure, and taking his queue from a number of other anarchist comrades in a similar predicament, early in 1892 he fled to the United States of America. On his arrival at New York he met up with the circle around Emma Goldman, Alexander Berkman, and politically like-minded comrades from Germany. Sepp Orter discovered in himself a talent for activism, turning out to have a flair for public speaking. During 1892 he was also the editor of the New York version of , published by the "Radical Workers' Association" ("Radikaler Arbeiter Bund") and the "Autonomy" group which also numbered among its members Josef Peukert. The stay in America was cut short, however. The authorities suspected that Oerter had somehow been involved in Alexander Berkman's attempt to assassinate a wealthy businessman called Henry Clay Frick. Those suspicions appear not to have been entirely unfounded. With financial assistance from Emma Goldman, Sepp Oerter returned to Germany. He travelled via London where he arrived in October, and where the editorial group publishing "Autonomy" gave him a mission to take printed material across Belgium to the German frontier in order to effect a clandestine introduction of the anarchist propaganda to Germany. Sepp Oerter was able to complete his mission with the help of his brother Fritz who had stayed behind when Sepp had escaped to America.

Input: Consider Input: Question: What team did Drogba score the winning goal against in the final? Passage:In July 2004, Drogba moved to Premier League club Chelsea for a club record £24 million fee, making him the most expensive Ivorian player in history. In his debut season he helped the club win their first league title in 50 years, and a year later he won another Premier League title. His displays saw him named in the FIFA World XI for 2007. In March 2012, he became the first African player to score 100 Premier League goals. Just two months later, he scored in Chelsea's 2012 FA Cup Final win over Liverpool to become the first (and , the only) player to score in four separate FA Cup finals. He also played in the 2012 UEFA Champions League Final, in which he scored an 88th-minute equaliser and the winning penalty in the deciding shoot-out against Bayern Munich. After spending 6 months with Shanghai Shenhua in China, and one and a half seasons with Turkish club Galatasaray where he scored the winning goal in the final of the 2013 Turkish Super Cup, Drogba returned to Chelsea in July 2014. With a career record of scoring 10 goals in 10 finals winning 10 trophies at club level, Drogba has been referred to as the "ultimate big game player." He joined Canadian club Montreal Impact in 2015 as a Designated Player and played 41 matches over two seasons, scoring 23 goals. Drogba became a player–owner for Phoenix Rising of the United Soccer League in 2017, and retired a year later at the age of 40.
