সঠিক উত্তর হচ্ছে: সাবেক চেকোস্লোভাকিয়ার সমাজতন্ত্রবিরোধী আন্দোলন
ব্যাখ্যা: The Velvet Revolution or Gentle Revolution was a non-violent transition of power in what was then Czechoslovakia, occurring from 17 November to 29 December 1989. Popular demonstrations against the one-party government of the Communist Party of Czechoslovakia included students and older dissidents. The result was the end of 41 years of one-party rule in Czechoslovakia, and the subsequent dismantling of the command economy and conversion to a parliamentary Republic. \n[Source: St. Martin\'s press]
