Final answer:
During the Holocaust, the Nazis used the yellow Star of David as a symbol to identify Jews. The book titled, "The Boy Who Dared," serves as a poignant reminder of the discrimination and persecution that Jews endured during that time.
Step-by-step explanation:
The yellow Star of David symbolizes Jewish identity in The Boy Who Dared. The protagonist, Helmuth, is a young German boy who resists Nazi propaganda and is ultimately punished for his actions. The yellow Star of David is a marker used by the Nazis to identify Jews, and it becomes a powerful symbol of Helmuth's Jewish identity and his defiance against the Nazi regime.
