Which is a complete sentence?

The measles virus causes a rash, fever, cough, and runny nose.

Molasses cookies are my favorite, Todd prefers lemon bars.

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 run-on sentence is made up of two independent clauses 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 made up of two independent clauses joined by a comma and a coordinating 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 measles virus causes a rash, fever, cough, and runny nose is a complete sentence. The subject is the measles virus, and the verb is causes.
