Question: How old was Angela Merkel when Kohl resigned his honorary chairman position at CDU? Passage:As Chancellor Kohl was strongly committed to European integration and French–German cooperation in particular; he was also a steadfast ally of the United States and supported Reagan's more aggressive policies in order to weaken the Soviet Union. Kohl's 16-year tenure was the longest of any German Chancellor since Otto von Bismarck. He oversaw the end of the Cold War and the German reunification, for which he is generally known as Chancellor of Unity. Together with French President François Mitterrand, Kohl was the architect of the Maastricht Treaty, which established the European Union (EU) and the euro currency. Kohl was also a central figure in the eastern enlargement of the European Union, and his government led the effort to push for international recognition of Croatia, Slovenia, and Bosnia and Herzegovina when the states declared independence. He played an instrumental role in solving the Bosnian War. Domestically, Kohl's policies focused on economic reforms and later also on the process of integrating the former East Germany into the reunited Germany, and he moved the federal capital from the "provisional capital" Bonn back to Berlin, although he himself never resided there because the government offices were only relocated in 1999. Kohl also greatly increased federal spending on arts and culture. After his chancellorship, Kohl's reputation suffered domestically because of his role in the CDU donations scandal and he had to resign from his honorary chairmanship of the CDU after little more than a year in January 2000, but he was partly rehabilitated in later years. The later Chancellor Angela Merkel started her political career as Kohl's protegée.

Question: When was the firm that designed the Oregon library established? Passage:The Oregon Library was designed by Chicago architects Pond and Pond. The Ponds were members of the Eagle's Nest Art Colony, founded by Lorado Taft, and their association with Taft and the colony led them to design the library. Their design was influenced by the colony, and a combination of two architectural styles, Classical Revival and the Arts and Crafts movement. The completed library included a second floor art gallery to which members of Eagle's Nest donated works for a permanent collection. The gallery's collection includes 64 paintings and sculptures as well as a Currier and Ives lithograph collection appraised at US$700,000. The Oregon Public Library was listed on the U.S. National Register of Historic Places in 2003, three years later it was included as a contributing property in a historic district that received the National Register designation.

question:
Question: How many seasons did the head coach from 2004 work for the Buffalo Bills? Passage:On November 30, the Bills beat the Cleveland Browns giving them their seventh win, which not only improved on the previous season, in which they finished 6-10 for the third time since 2003 (they finished 6-10 in 2009 and 2011, the latter of which after they started 5-2), but it also gives them their best start entering December since the 2000 Buffalo Bills season, in which they finished 8-8 and missed the playoffs. With a win against the Green Bay Packers on December 14, the Bills broke a league-leading streak of nine consecutive losing seasons dating back to 2005; however, the next week's 26-24 loss to the Oakland Raiders eliminated them from playoff contention for the 15th consecutive year, continuing a league-leading drought. The team finished with a 17-9 win against the New England Patriots, who were resting the starters in preparation for a playoff run; the win was the first time the team had won at Gillette Stadium (they had lost all 12 previous attempts) and established the team's first winning season since 2004 (former head coach Mike Mularkey's first season).
