Answer:
Classification
Step-by-step explanation:
I remember doing exercises like this when I was in ENG101 in comm college. I say that this would be Classification because the three types of verbs are very neatly laid out into distinct categories or classifications. It could have been definition if its main purpose was to solely define each of these terms, and it is for sure not preface or advantage and disadvantage. So, this is why I would say Classification for my answer.
