Step 1 : Introduction to the question "4. You'll never play trivia in Oradour-sur-Glane again. This village in France was abandoned in June 1944. For what reason?"
...1. There was an outbreak of plague. 2. The inhabitants were abducted by aliens. 3. It was bought by a Texan millionaire and transported to America. 4. It was the site of a Nazi atrocity. On June 10th 1944, 642 men, women and children were rounded up and shot or burned to death by the Nazis. This was virtually the entire local population and is believed to have happened because the SS confused the village with the nearby Oradour-sur-Vayres, in which they believed that a German officer was being held. The village has remained empty as a memorial.
