Final answer:
The phrase 'the middle of May' is an example of alliteration, a literary device involving the repetition of initial consonant sounds in a sentence. Other given options do not apply.
Step-by-step explanation:
The phrase 'the middle of May' is an example of the literary device known as alliteration. Alliteration involves the repetition of the same initial consonant sound in a series or a group of words in a sentence. In this case, you can see that the letter 'm' repeats in the phrase 'middle of May,' hence making it an instance of alliteration. Other literary devices, such as assonance, metaphor, and consonance, do not apply here. Assonance involves the repetition of vowel sounds, metaphor is a figure of speech comparing two unlike things, and consonance is the repetition of consonant sounds anywhere in the words, not just at the beginning.
