To categorize the items into "Things that create mood" and "Things that create tone," we can analyze the emotional atmosphere and the attitude conveyed:
Things that create mood:
- a large moor at dusk
- two servants in distress, carrying lanterns
Things that create tone:
- a bitter, sarcastic remark by a grieving wife
- two parents stressed over finances, being interrupted by a happy child
This classification is based on the idea that mood pertains to the overall emotional setting (atmosphere) created by a setting or scene, while tone refers to the speaker's attitude or the way they express their emotions.
