Answer:
I don't know which excerpt you are talking about but omniscient narration is when the narrator (or speaker) knows everything about the story.
Step-by-step explanation:
For example; here are two mini paragraphs from stories I made up, using omniscient and limited third-person narration.
Omniscient (all knowing)
On that day, Millie walked to her school. Soon she would meet her best friend, Jacob, who had gotten hurt from climbing a tree. She had no idea her day was about to be spent worrying over her friend's broken bones, as she walked on the sidewalk.
Limited (limited to knowledge and doesn't know everything)
On that day, Millie walked to school, feeling happy. What a great day! She thought joyfully. Once she got to the school, she was shocked. Her friend Jacob was standing in the courtyard, with a cast wrapped around his swollen leg. Millie couldn't believe this had happened! She frantically ran to her friend and began demanding what happened.
Hope this helps!!! :)
