Early in the story, when Jack's father tells him about finding his mother in a catalog and he lies about her, Jack wonders, "What kind of woman puts herself into a catalog so that she can be bought?" Later, he is focused on on-campus recruiting season, and tells us, "I schemed about how to lie to the corporate recruiters most effectively so that they'll offer to buy me." Why do you think the story draws this parallel between Jack and his mother both lying in order to be "bought"?

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.

alone =having no one else present.
