Explanation:
Adverbs are a part of speech that modifies a verb, an adjective or another adverb. They tell us how, when, where or in what manner something happened. Adverbs usually end on -ly, but that is not the only suffix they can end on.
In the given sentence by looking at the form, we can find several adverbs: daily, healthy, closely, early. But only closely modifies the verb. The rest modifies nouns, so they are adjectives.
