I can tell you the first one is " last year I could sing very well" not sure about the others I'm so sorry ( maybe its right )
When a novel is using the first person point of view, the reader is getting the impression that he is a part of a story, he is completely immersed in it. First person narrators tend to be more subjective and closer to the reader in that they think about what the reader may think, and not just narrate the events. On the other had, third person narrators are completely different - they give off this vibe of distance, and they are quite objective, usually tending to just narrate what is going on around them.
Hope this helps!
This is a free response question right? I would suggest maybe watching some videos about this guy because my brother had the same question (he's in k12) and the videos should really help. its ok if you didn't read the book. Elie Wiesel is a surviver of the horrible holocaust that took place wiping out millions of Jews. He's said himself in some interviews that he believes staying silent isnt the right thing to do. just watch a few vids about him and you should be about to easily answer this question. Hope I helped:)
