Which of the following is one of the eight standard parts of speech? a. subject b. article c. modifier d. preposition

D. Preposition > The eight parts of speech (traditional grammar classifies words): the verb, the noun, the pronoun, the adjective, the adverb, the preposition, the conjunction, and the interjection. Each part of speech explains how the word is used (not what the word is). The same word can be a noun in one sentence and a verb/an adjective in the next.

A preposition links pronouns, nouns, and phrases to other words in a sentence. It usually indicates the temporal, spatial or logical relationship of its object to the rest of the sentence. The word/phrase that the preposition introduces is called the object of the preposition.

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.
