Answer:
True
Step-by-step explanation:
I believe you are referring to the book "The Devil's Arithmetic" written by Jane Yolen. In this book, we can, in fact, recognize the harmful effects of prejudice, where prejudice against Jews causes concentration camps to be created, where Jews suffer the greatest ill-treatment just because they do not abandon their beliefs.
In this book we got to know a girl named Hanna who belongs to a Jewish family that lives in New York. Hanna does not understand the impotence that the family gives to the experiences they have had in the past and is bored when they start talking about holocaust, Nazism and anti-Semitism. However, she is transported to the past and goes to Poland dominated by Nazi Germany. Hanna is captured, taken to a concentration camp where she suffers everything that the Jews suffered. This makes her understand the importance of these stories, especially of the survivors.
