[EX Q]: Passage: Between Bingen and Bonn, the Middle Rhine flows through the Rhine Gorge, a formation which was created by erosion. The rate of erosion equaled the uplift in the region, such that the river was left at about its original level while the surrounding lands raised. The gorge is quite deep and is the stretch of the river which is known for its many castles and vineyards. It is a UNESCO World Heritage Site (2002) and known as 'the Romantic Rhine', with more than 40 castles and fortresses from the Middle Ages and many quaint and lovely country villages. Question: What is the section of the Rhine Gorge recognized by UNESCO called?
[EX A]: the Romantic Rhine

[EX Q]: Passage: The first buildings of the University of Chicago campus, which make up what is now known as the Main Quadrangles, were part of a 'master plan' conceived by two University of Chicago trustees and plotted by Chicago architect Henry Ives Cobb. The Main Quadrangles consist of six quadrangles, each surrounded by buildings, bordering one larger quadrangle. The buildings of the Main Quadrangles were designed by Cobb, Shepley, Rutan and Coolidge, Holabird & Roche, and other architectural firms in a mixture of the Victorian Gothic and Collegiate Gothic styles, patterned on the colleges of the University of Oxford. (Mitchell Tower, for example, is modeled after Oxford's Magdalen Tower, and the university Commons, Hutchinson Hall, replicates Christ Church Hall.) Question: Hutchinson Hall was designed to look like what Oxford hall?
[EX A]:
Christ Church Hall
