Final answer:
Annemarie in 'Number the Stars' faces her challenge of helping her Jewish friend escape the Nazis during World War II with bravery and resourcefulness, while Ben in 'The Boy Who Fought Hitler' joins the resistance and confronts the Nazis directly.
Step-by-step explanation:
In 'Number the Stars,' Annemarie faces the challenge of helping her Jewish friend Ellen escape from the Nazis during World War II. Annemarie is a young girl who must navigate dangerous situations and make difficult choices to protect her friend. In 'The Boy Who Fought Hitler,' Ben faces the challenge of joining the resistance movement against Hitler in World War II. Ben is a teenage boy who risks his life to fight against the Nazi regime.
The main difference in how Annemarie and Ben face their challenges is their age and the roles they play. Annemarie is a young girl who relies on her bravery, resourcefulness, and ability to blend in to protect Ellen. Ben, on the other hand, is a teenage boy who actively joins the resistance and directly confronts the Nazis. Both characters show courage and determination in facing their challenges, but they do so in different ways.
