What is the difference between tone and mood?
The answer, above, is D. A writer’s tone is his or her attitude towards his or her subject. It can be involved in creating mood, but the mood of a story (or poem or whatever) is similar to atmosphere; it’s the feeling created in the reader. For this reason, some words can describe either tone or mood, such as “cheerful” or “sad”; others can describe only one. The mood of a story could be described as “eerie” or “suspenseful”; the tone could not because one cannot have a suspenseful attitude.
