[EX Q]: 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 FrenchGerman 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 Francois 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 protegee.

[EX Q]: Question: Did the group that Stinson founded have more than three members? Passage:Gregory E. Stinson, better known as G. E. Stinson (born in Kingfisher, Oklahoma), is an American guitarist and founding member of new age/electronic musical group Shadowfax. Inspired by blues masters such as Bo Diddley and Muddy Waters, Stinson experimented with blues, jazz and other musical genres before co-founding Shadowfax in 1974. He remained with the band for six albums. He departed Shadowfax after recording The Odd Get Even (1989), entering the Los Angeles underground music community to refine his 'extended technique' and 'frequency manipulation'. Since then he has worked with a number of musicians on various projects, including Napalm Quartet, Splinter Group, Stinkbug, Metalworkers, Alex De Grassi, Devin Sarno and others. In 2000, he collaborated with drummer Gregg Bendian, violinist Jeff Gauthier, and bassist Steuart Liebig on an album of collective improvisational pieces recorded live in the studio, entitled Bone Structure. Released in 2003, it was given four stars by Jim Andrews in DownBeat magazine.

[EX Q]: Question: When did the expedition that John Colter was apart of in 1807 begin? Passage:Europeans may have ventured into the northern sections of the state in the late 18th century. Most of the southern part of modern-day Wyoming was nominally claimed by Spain and Mexico until the 1830s, but they had no presence. John Colter, a member of the Lewis and Clark Expedition, was probably the first American to enter the region in 1807. His reports of thermal activity in the Yellowstone area were considered at the time to be fictional. Robert Stuart and a party of five men returning from Astoria, Oregon discovered South Pass in 1812. The route was later followed by the Oregon Trail. In 1850, Jim Bridger located what is now known as Bridger Pass, which was later used by both the Union Pacific Railroad in 1868, and in the 20th century by Interstate 80. Bridger also explored the Yellowstone region and like Colter, most of his reports on that region of the state were considered at the time to be tall tales. During the early 19th century, fur trappers known as mountain men flocked to the mountains of western Wyoming in search of beaver. In 1824, the first mountain man rendezvous was held in Wyoming. The gatherings continued annually until 1840, with the majority of them held within Wyoming territory.
