Read the excerpt from Billy Collins’s "Man Listening to Disc." In fact, I would say my delight at being suffused with phrases from his saxophone— some like honey, some like vinegar— is surpassed only by my gratitude to Tommy Potter for taking the time to join us on this breezy afternoon with his most unwieldy bass and to the esteemed Arthur Taylor who is somehow managing to navigate this crowd with his cumbersome drums. Which of the following suggestions would best enhance a reader’s understanding of this poem?
a. Read a variety of sources about the style and instruments used by jazz musicians.
b. Search medical journals to learn how different types of music can affect a person’s mood.
c. Review case studies on hearing loss due to the prolonged listening of loud music.
d. Evaluate several poems to learn about the techniques authors use to convey their ideas.

A). Read a variety of sources about the style and instruments used by jazz musicians.

Explanation:

As per the question, the suggestion that would best comprehend the readers' understanding of the given poem 'Man Listening to Disc' by Billy Collins would include 'reading a variety of sources about the style as well as instruments employed by Jazz musicians.' This reading would serve to provide a contextual information that would assist the readers to have a comprehensive understanding of the poem as the poem involves a detailed description of musical instruments like 'Saxophone', 'drums', etc. and musical terms like 'bass', etc. which requires such reading for a better understanding. Thus, option A is the correct answer.

faulty parallelism is a grammar construction where there is no balance in the parts of a sentence they have a similar meaning but the grammar structure is not equivalent.

the correct version of this faulty parallelism in the sentence is:

jefferson wrote the declaration of independence, and he was the nation's third president.

the problem with the first version is that the sentence:

"jefferson was both the writer of the declaration of independence"

presents jefferson as both a subject and an agent for the verb "write" because if he was "the writer" then the declaration of independence was written by him, besides that fact, the sentence presents a dependent clause.

while the second sentence:

he was the nation's third president.

presents a basic subject+verb+object structure

so, to give a proper balance to the structure, or better said, to give a parallel structure, we must write a basic s+v+o structure in both sentences:

jefferson wrote the declaration of independence, and he was the nation third president.

i believe it may be the hope this sorry if i'm wrong.
