Which is a run-on sentence?

Puts the towel back in the bathroom.

The book disappointed Stacy, she didn't like the sad ending.

key idea

A sentence is a group of words that forms a complete thought. It has both a subject and a verb.

My friends walk along the path.

A sentence fragment is a group of words that does not express a complete thought. It is usually missing a subject or a verb.

Knows the answer.

This is a sentence fragment. It is missing a subject.

Who knows the answer? She knows the answer.

The bright red car.

This is a sentence fragment. It is missing a verb.

What did the bright red car do? The bright red car stopped.

A run-on sentence is made up of two sentences that are joined without end punctuation or with just a comma.

I knocked on the door it opened.

It started raining, we ran inside.

To fix a run-on sentence, separate it into two sentences. Add end punctuation after the first sentence, and capitalize the second sentence.

I knocked on the door. It opened.

It started raining. We ran inside.

You can also fix a run-on sentence by rewriting it as a compound sentence. A compound sentence is two sentences joined by a comma and a conjunction such as and, but, or, or so.

I knocked on the door, and it opened.

It started raining, so we ran inside.

solution

The book disappointed Stacy, she didn't like the sad ending is a run-on sentence. It has two sentences that are joined by just a comma: The book disappointed Stacy and She didn't like the sad ending.
