Select the sentence that contains a noun clause. which phrase contains a noun clause?
george washington, often called "the father of his country," was born in 1732. he was a general during the american revolution. washington became the first president of the united states of america in 1789. he fell ill and died in 1799, but we know that his legacy continues today.

I just took the test, the correct answer is .. “He fell ill and died in 1799, but we know that his legacy continues today.”

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.
