What is wrong with this sentence, and why? "To tell us all what really happened."
Select one:

It is a sentence fragment because it has two independent clauses.

It is a run-on sentence because it does not have a subject.

It is a sentence fragment because it does not have a subject.

It is a run-on sentence because it is a dependent clause

It is a sentence fragment because it does not have a subject.

Explanation:

First option: The first option is incorrect because there are NO independent clauses, which are a group of words that can stand by itself. Because there's a missing subject, it cannot stand by itself.

Second Option: The second option is incorrect because run-on sentences result from two or more complete sentences without any punctuation. This is a fragment, so it can't even be a sentence.

Third Option: The third option is correct because as it states, "it does not have a subject"; only a predicate.

Fourth Option: The fourth option is incorrect because run-on sentences have two complete sentences as one sentence without any punctuation. This isn't even a sentence, so it can't be a run-on sentence.
