Which sentence has an error in comma usage? Donna likes biology, it is her favorite subject.

Lauren bought a package of paper, a box of pencils, and a notebook.

My brother was sleeping, and my father was watching television.

Nathan finished his homework, so he went to the movies.


Answer 1

The correct answer is A. Donna likes biology, it is her favorite subject.


According to grammar rules, it is correct to use comma to separate different items in a list or in the case of compound sentences that link two ideas that have the same level of importance through conjunction such as and, or, but, so, because in this case, the comma is placed before the conjunction.

However, it is not correct to use a comma to link two complete sentences as the correct form is to use a semicolon (;). This type of mistake occurs in the case of "Donna likes biology, it is her favorite subject", because in this there are two independent clauses or complete sentence "Donna likes biology" and "it is her favorite subject", which is a grammatical mistake known as comma split. Therefore, the sentence that has an error in comma usage is "Donna likes biology, it is her favorite subject".

Answer 2
Answer: "my brother is sleeping and my father was watching TV" is the error. No comma is needed in that sentence

What is the overall tone of this passage? angry
authoritative <------ I believe it is this one.

Society is a wave. The wave moves onward, but the water of which it is composed does not. The same particle
does not rise from the valley to the ridge. Its unity is only phenomenal. The persons who make up a nation today,
next year die, and their experience with them.
And so the reliance on Property, including the reliance on governments which protect it, is the [5] want
of self-reliance. Men have looked away from themselves and at things so long, that they have come to esteem
the religious, learned, and civil institutions as guards of property, and they deprecate assaults on these, because
they feel them to be assaults on property. They measure their esteem of each other by what each has, and not
by what each is. But a cultivated man becomes ashamed of his property, out of new respect for his nature.
Especially he hates [10] what he has, if he see that it is [10] accidental,—came to him by inheritance, or gift, or
crime; then he feels that it is not having; it does not belong to him, has no root in him, and merely lies there,
because no revolution or no robber takes it away. But that which a man is, does always by necessity acquire, and
what the man acquires is living property, which does not wait the beck of rulers, or mobs, or revolutions, or fire,
or storm, or bankruptcies, but perpetually renews itself wherever the man breathes… It is only as a man puts off
all [15] foreign support, and stands alone, that I see him to be strong and to prevail. He is weaker by every
recruit to his banner. Is not a man better than a town? Ask nothing of men, and in the endless mutation, thou
only firm column must presently appear the upholder of all that surrounds thee. He who knows that power is
inborn, that he is weak because he has looked for good out of him and elsewhere, and so perceiving, throws
himself unhesitatingly on his thought, instantly rights himself, stands in the erect [20] position, commands his
limbs, works miracles; just as a man who stands on his feet is stronger than a man who stands on his head.
So use all that is called Fortune. Most men gamble with her, and gain all, and lose all, as her wheel rolls.
But do thou leave as unlawful these winnings, and deal with Cause and Effect, the chancelors of God. In the Will
work and acquire, and thou hast chained the wheel of Chance, and shalt [25] sit hereafter out of fear from her
rotations. A political victory, a rise of rents, the recovery of your sick, or the return of your absent friend, or
some other favorable event, raises your spirits, and you think good days are preparing for you. Do not believe it.
Nothing can bring you peace but yourself. Nothing can bring you peace but the triumph of principles.
