Input: Consider Input: Question: Which country that Austria has a border barrier with has the highest population? Passage:Austrian border barriers are border barriers and migration management facilities constructed by Austria between November 2015 and January 2016 on its border with Slovenia and in 2016 on its border with Italy, as a response to European migrant crisis. 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. The barrier on the Slovenian border is several kilometres long, located near the busiest border crossing, Spielfeld-Šentilj, and includes police facilities for screening and processing migrants. Another migration management facility with barriers located on Austria's Italian border near Brenner, South Tyrol was constructed in 2016.

Input: Consider Input: Question: Who is the wife of the Tigers pitcher who was name World Series MVP? Passage:The 2012 World Series was the championship series of Major League Baseball's (MLB) 2012 season. The 108th edition of the World Series, the series was a best-of-seven playoff between the National League (NL) champion San Francisco Giants and the American League (AL) champion Detroit Tigers; the Giants won in a four-game sweep. This marked the Giants' seventh World Series title in franchise history, their second in San Francisco (they won five in New York), and their second in a three-year period (2010–2012). Their World Series sweep was the first by an NL team since the Cincinnati Reds swept the Oakland Athletics in the 1990 series and the first NL sweep not by the Reds since 1963, when the Los Angeles Dodgers swept the New York Yankees. This was also the first World Series since 1988 to feature both of that year's League MVPs (Miguel Cabrera for the AL and Buster Posey for the NL). The Giants' Pablo Sandoval, who in Game 1 tied a record by hitting three home runs in one World Series game, two off Tigers' ace pitcher Justin Verlander, was named the World Series Most Valuable Player (MVP).

Input: Consider Input: Question: Which European director was older, Cocteau or Bergman? Passage:One of the main film genres associated with the Weimar Republic cinema is German Expressionism which was inspired by the expressionist movement in art. Expressionist movies relied heavily on symbolism and artistic imagery rather than stark realism to tell their stories. Given the grim mood in post-WWI, it was not surprising that these films focused heavily on crime and horror. The film usually credited with sparking the popularity of expressionism is Robert Wiene's The Cabinet of Dr. Caligari (1920), produced by Erich Pommer. The film tells the story of a demented hypnotist who is using a sleepwalker to perform a series of murders. The film featured a dark and twisted visual style - the set was unrealistic with geometric images painted on the floor and shapes in light and shadow cast on walls, the acting was exaggerated and the costumes bizarre. These stylistic elements became trademarks of this cinematic movement. Other notable works of Expressionism are Friedrich Wilhelm Murnau's Nosferatu (1922), Carl Boese and Paul Wegener's  (1920) and Metropolis (1927) directed by Fritz Lang. The Expressionist movement began to wane during the mid-1920s, but perhaps the fact that its main creators moved to Hollywood, California, allowed this style to remain influential in world cinema for years to come, particularly in American horror films and film noir and in the works of European directors such as Jean Cocteau and Ingmar Bergman.
