Answer and Explanation:
1. Wiesel is describing the experience he had as a Jewish prisoner, exploited and ill-treated in a Nazi concentration camp. In his work he shows all the horrors he went through, in addition to reinforcing how this experience was unfair and without justifiable justifications for it to happen.
2. He uses first-person narration to show the feelings and thoughts of the narrator, who represents him to the fullest. This creates an immersive reading, making the reader see himself in that precarious situation he is reading.
3. The narration is important because it creates the whole foundation to which, not only the story is shown, but also the themes and reflections that are raised by the narrative, which provoke reflection, emotion and understanding.
