 disfluent question: What is er where does the Middle Rhine flow between Bingen and Bonn? 
 context: 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.
