Answer: The verb phrase in the sentence provided is "will realize".
Step-by-step explanation: A verb phrase is made up of a main verb and a modal or auxiliary verb. Moreover, in a verb phrase, the modal/auxiliary verb comes before the main verb, In the sentence "Elsie will very soon realize that she doesn’t need to finish her chores", the verb phrase is "will realize", which consists of the main verb "realize" and the modal verb "will". In this case, the modal verb was added to indicate future time reference. "Very soon" is not part of the verb phrase: it is an adverb phrase that snuck in between the parts of the verb phrase.
