Answer:
4) The narrative will change depending on the narrator's tone and point-of-view.
Step-by-step explanation:
It is the narrator's role to tell the readers/audiences about what's happening in the story. He/She becomes the readers' lens, thus, their knowledge will largely rely on what is being narrated.
It is important to carefully pick a narrator when planning to write a narrative. A story can take a first-person perspective wherein the reader will have a deep connection with the main character in the story. However, his point-of-view will only be limited to what that character thinks. It can take the second-person perspective wherein the writer or author wants to directly convey his message to the reader. Another perspective is the third-person wherein the reader will know everything that is happening in the story. A change in perspective changes the tone of the narrator, as well as his point-of-view. This largely affects the readers'/audiences' understanding.
