Answer: 1. Fear, 2. Excitement, and 3. Objectivity.
Explanation: The tone of a text or sentence is the author's or speaker's attitude towards the audience, the subject or even the characters of the text. There are many different kinds of tones, like: positive, negative, objective, sad, angry, etc. The first sentence is an example of a tone of fear ("terror seized her"), in the second sentence we can see an example of a tone of excitement, and in the third one we can see a tone of objectivity (because it is neutral).
