Step-by-step explanation:
The word in the sentence “He tore into his presents” that indicates an excited tone is “tore.” This choice of word suggests a vigorous and eager action, typically associated with excitement or enthusiasm. When a person “tears” into something, it usually means they do so quickly and without hesitation, which is a common reaction when someone is excited, especially about opening gifts. It is similar in tone to phrases found in the provided reference texts, such as “seized with the joyful curiosity” and “tore away the excelsior,” both of which also convey excitement through the choice of verbs indicating rapid, forceful action.

The word “tore” in the context of opening presents generally signifies a positive, excited response to a highly anticipated event or item.
