It’s to “correct mistakes”.
Onomatopoeia.
Imagery is incorrect as poets use that in order to help a reader visualize the scene or actions within the poem.
Simile is incorrect as similes are used to make analogies or comparisons between two objects or things.
Personification is incorrect as it is used to give a non-human being humanistic traits, for example, "The wind sang throughout the cold winter night."
Onomatopoeia, however, is correct as this is used to term sounds within a poem such as Wham! Bam! etc.

The correct answer would be helping verbs. The helping verbs are combined with the main verbs to indicate time, possibility and other kinds of meaning. The helping verbs' function is to help extend the meaning of the main verbs by adding more detail on it. Helping verbs are very essential in the formation of different tenses of the verb.
