question: The Rotor is an amusement park ride that first demonstrated during a festival held in what city?
answer: Munich
context: Title: Spook-a-Rama
  Passage: The Spook-a-Rama is a dark ride from the Pretzel Amusement Ride Company located at Deno's Wonder Wheel Amusement Park on Coney Island and run by Million Amusement Corp..  The rider is pulled around in a car resembling an old wooden barrel.  These barrels look like connected cars, but separate from each other at the beginning of the ride, so the rider must go in alone, passing paintings that change imagery, and a skeleton before the car itself forces the doors open.  Inside, the ride is one large, poorly lit room.  The ride recently had a major renovation done by Scarefactory inc. and more information will surface with the opening of Deno's Wonder Wheel Amusement Park for the 2013 season.
  Title: Oktoberfest
  Passage: Oktoberfest (] ) is the world's largest Volksfest (beer festival and travelling funfair).  Held annually in Munich, Bavaria, Germany, it is a 16- to 18-day folk festival running from mid or late September to the first weekend in October, with more than 6 million people from around the world attending the event every year.  Locally, it is often called the Wiesn, after the colloquial name for the fairgrounds, Theresa's meadows ("Theresienwiese").  The Oktoberfest is an important part of Bavarian culture, having been held since the year 1810.  Other cities across the world also hold Oktoberfest celebrations that are modelled after the original Munich event.
  Title: Swing Around
  Passage: The HUSS Swing Around is an amusement park ride formerly manufactured by HUSS.  It was HUSS Maschinenfabrik's first ride model, debuted in 1969.  It is not manufactured by the company anymore, but there are a handful of known units left around the world.  The ride rotates in a circle, and the arms swing out, and then come in.  They keep on doing this during the ride, in bigger and bigger increments until the very end, where they all swing out, using pneumatic pressure.  Most parks require riders to be 42 inches tall to ride; anyone under 48 inches tall must ride with an adult.
  Title: Rotor (ride)
  Passage: The Rotor is an amusement park ride, designed by German engineer Ernst Hoffmeister in the late 1940s.  The ride was first demonstrated at Oktoberfest 1949, and was exhibited at fairs and events throughout Europe during the 1950s and 1960s.  The ride still appears in numerous amusement parks, although travelling variants have been surpassed by the Gravitron.
