Final answer:
Elie Wiesel switches from using 'I' to 'we' and 'us' in his speech for inclusivity and solidarity.
Step-by-step explanation:
Elie Wiesel switches from using the pronoun 'I' at the beginning of his speech to using 'we' and 'us' later on. This shift in pronouns is a rhetorical device known as inclusivity and solidarity. By using 'we' and 'us', Wiesel is creating a sense of unity and shared responsibility with his audience, emphasizing that they are all affected by the issue he is addressing.
