Answer:
Mrs. Schachter kept screaming "fire" even though she was getting beaten for it because she had foreseen what will happen to them, the Jews. She is like a warning for what will be the fate of the people and how most of them will end up.
Explanation:
The memoir Night by Elie Weisel tells the story of how the Jews were discriminated against and treated inhumanely by the German Nazis. The book became one of the most read and first-person accounts of the horrors of the Holocaust, one of the greatest genocide in world history.
Mrs. Schachter and the captured Jews were stuffed into the cattle cars and transported to other camps for their imprisonment. She was with her ten-year-old son. Along the way, she began screaming "Fire! I see a fire! I see a fire! [. . . .] This terrible fire. Have mercy on me". This happened not just once or twice but more than thrice. She was badly beaten up for causing panic among them and was even gagged. But she kept on shouting about the fire.
Her 'vision' of the fire seems to be the foreshadowing of the fate of the Jews. Most of them will be put in the chamber and burned. She seems to foresee what will happen to them. And even though she was beaten up for shouting and claiming she saw a fire, she kept on repeating her claim to warn them of their fate, which, unfortunately wasn't understood by the people at that time.
