If you did or said something slightly irregular at the farthest end of the street from your cottage, where your legitimate bosses lived, somebody would be watching and ready to call out: "Mira, que muchachito tan malcriado." What does the author mean by "legitimate bosses"?

Parents.

Explanation:

The given excerpt is taken from Barrio Boy. Barrio Boy is an autobiography of Ernesto Galarza. The author shares his experience of moving from a small village to a barrio.

The phrase used by the author in the excerpt 'legitimate bosses' is used to refer to someone who is the true head, or rightful owner, or the legal head.

In the given context the author has used the phrase to refer to the parents as the legal head, or rightful owner of a cottage or house are parents.

So, the correct answer is parents.

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.
