Answer: commas and semicolons
Explanation:
Tone is achieved through word choice (diction), sentence construction and word order (syntax), and by what the viewpoint character focuses on. Tone is created or altered by the way the viewpoint character/narrator treats the story problem and other characters, and by the way they respond to the events surrounding them.
Mood is what the reader feels while reading a scene or story. It’s not the reader’s emotions, but the atmosphere (the vibe) of a scene or story. It’s what the reader reads or feels or notices.
