Final answer:
Elie Wiesel and his father were advised to lie about their ages in the book 'Night' to increase their chances of survival upon arriving at Auschwitz during the Holocaust.
Step-by-step explanation:
The student question pertains to the advice given to Elie Wiesel and his father in the book Night, a memoir about his experiences during the Holocaust. Upon arrival at Auschwitz, a fellow prisoner advised them to lie about their ages. Elie was instructed to say he was 18 instead of 15, and his father was told to say he was 40 instead of 50. This advice was given to increase their chances of passing the selection process. Young children and older men were often deemed unfit for labour and sent directly to the gas chambers or killed. By lying about their ages, Elie and his father could present themselves as fit for work, thereby potentially saving their lives, at least temporarily.
