Answer:
When the narrator's point of view is third-person omniscient, it means that he is not part of the story, meaning that the narrator is external; this type of narrator knows everything about the characters but it remains unnamed.
Step-by-step explanation:
For example from a novel written by American author Gary D. Schmidt (whose works expand to children's and young adults' fields), we can see that the narrator uses the pronouns he and she, which are the third person of singular; on the other hand we can see that Turner doesn't know some Lizzie's actions, but the narrator does, indicating that it is omniscient.
