Hello. You have not provided either the text or answer options for this question. This makes it impossible for me to answer it. However, I will try to help you as best I can.
To answer this question, you will have to read the entire text, so you will be able to identify not only the climax of the story but also the theme. Climax refers to the moment when the biggest plot challenge will be faced. In climax, characters face the biggest enemy or the biggest difficulty they have. You must identify this moment by the paragraph that indicates that this "fight" will begin.
The text's theme, on the other hand, refers to the message and teaching that the author wishes to convey through the story. You will be able to discover this theme, when you find out what subject the author is addressing in the story. Once this theme is discovered, you'll be able to associate it with the characters' speech and behavior.
The word from the passage that gives the best indication of the speaker's tone would be : scream
which gives the passage some sort of anxious/desperate tone with this sentence : his shadow shouts on a nightmare scream
hope this helps
