Answer:
True.
Step-by-step explanation:
An adverb is a word that modifies a verb, adjective, adverb, or even a whole sentence. They add meaning to the word it modifies in the sentence.
In the given sentence, the verb is "takes" while the adverb is "daily". This adverb modifies the manner of the verb "takes", which shows how often the multivitamin was taken by Miriam.
Thus, the correct answer is true.
