Answer:
Simple.
Explanation:
Verb aspect allows us to be specific about when things are happening in time:
Simple aspect verbs are just normally conjugated verbs. They don't use forms of "to have" or "to be" as helping verbs.
Progressive aspect shows that an action is ongoing using a form of "to be" alongside an -ing verb.
Perfect aspect allows us to talk about a completed action using a form of "to have" alongside a past tense verb.
"Munched" is a simple verb. It doesn't use any helping verbs.
