The best response that directly addresses how the reader's point of view can create suspense and humor is: A reader might know things that the characters do not.
When readers are aware of information or developments that the characters are oblivious to, it creates suspense because they can anticipate the potential consequences of the characters' actions or decisions. This knowledge can lead to a feeling of tension as readers wait for the characters to discover the truth or face a particular challenge.
Conversely, this dynamic can also generate humor, especially if the situation involves misunderstandings or ironic situations where readers can see the absurdity of the characters' decisions, while the characters remain unaware of the looming consequences. This gap between the reader's knowledge and the characters' ignorance is a key element in both building suspense and eliciting laughter.
