Final answer:
The sentence with proper parallel structure is A) Shannon loves to play the flute, march in the band, and watch the football games. It demonstrates parallel structure by consistently using the infinitive form of verbs, enhancing the clarity and rhythm of the sentence.
Step-by-step explanation:
The correct sentence that has proper parallel structure is: A) Shannon loves to play the flute, march in the band, and watch the football games. In this sentence, the parallel structure is maintained by using the infinitive form of the verbs ('to play', 'to march', 'to watch') consistently throughout the list of actions Shannon enjoys. Parallelism in writing is crucial as it creates symmetry and balance, makes concepts memorable, and provides clarity and rhythm to a sentence.
Ensuring subject-verb agreement is another important aspect of writing clear sentences. For example, the subject 'play', which is singular, should be followed by a singular verb 'comes' as in 'The play comes highly recommended.'
In the art of rhetoric, such as in speeches like President Kennedy's inaugural address, parallel structure is employed to emphasize and organize ideas engagingly and memorably.
