Example Input: Question: What concentration camp was Elie Wiesel at during the Holocaust? Passage:Holocaust is a 1978 American four part television miniseries which recounts the trajectory of the Holocaust from the perspectives of the fictional Weiss family of German Jews and that of a rising member of the SS, who gradually becomes a merciless war criminal. Holocaust highlighted numerous events which occurred up to and during World War II, such as Kristallnacht, the creation of Jewish ghettos, and later, the use of gas chambers. Although the miniseries won several awards and received positive reviews, it was criticized by others, such as the Holocaust survivor Elie Wiesel, who wrote in The New York Times that it was: "Untrue, offensive, cheap: as a TV production, the film is an insult to those who perished and to those who survived."
