Which of the following from the speech has a parallel structure?

A.
"our fathers brought forth upon this continent a new nation"
B.
"and dedicated to the proposition that all men are created equal"
C.
"that nation, or any nation so conceived and so dedicated"
D.
"which they who fought here have thus far so nobly advanced"

My answer is "c"

I agree.

The parallel structure in the speech can be found in option D: "which they who fought here have thus far so nobly advanced." This phrase follows a "which + relative pronoun + subject + verb" structure, which creates parallelism within the sentence.

To identify which of the following options has a parallel structure, we need to look for grammatical or structural similarities. Parallel structure refers to using the same grammatical form for two or more elements in a sentence. Let's analyze each option:

A. "our fathers brought forth upon this continent a new nation"
This statement does not have parallel structure because it describes a singular action by using past tense verb forms.

B. "and dedicated to the proposition that all men are created equal"
This statement does not have parallel structure either. It includes a combination of verbs and prepositions, but there is no consistent grammatical pattern.

C. "that nation, or any nation so conceived and so dedicated"
This option does have parallel structure. Both phrases "so conceived" and "so dedicated" use the same structure with "so" followed by a past participle verb.

D. "which they who fought here have thus far so nobly advanced"
This sentence structure does not exhibit parallelism. While it contains multiple phrases, they are not structured in a parallel manner.

Therefore, the correct answer is option C: "that nation, or any nation so conceived and so dedicated" which demonstrates parallel structure.
