[EX Q]: Question: Which country that Austria has a border barrier with has the highest population?

They are located on internal European Union borders, since Austria, Italy, and Slovenia are members of the EU and the free travel Schengen Area with a common visa policy.

[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.
