The correct answer is "Full of new ideas and eager to share, she would be a whirlwind in the otherwise quiet household"
Step-by-step explanation:
The metaphor is a common figure of speech used by authors to describe a person, object, or situation by comparing it to another object, idea, etc. Metaphor is part of figurative language, this means, the comparison is not literally but it conveys a meaning or idea.
Metaphor can be seen in the sentence "Full of new ideas and eager to share, she would be a whirlwind in the otherwise quiet household" because in the section "she would be a whirlwind" the author compares a female character to a whirlwind to describe how energetic this character is and the impact she will have in the household.
