3. Most people eat cereal, it's healthy is an example of a run-on sentence.
Explanation:
<u>Run-on sentences</u> occur when two or more independent clauses are not connected properly. A common type of <u>run-on sentence</u> is the one resulting from a <em>comma splice</em>, where the author failed to use a transitional expression and used just a comma to join two independent clauses -a clause that contains a subject and a predicate and can stand alone as a sentence. This is the case of sentence 3.
Run-on sentences are made when two sentences are put together without correct punctuation. Although, #1 is kind of redundant it's not a run-on sentence. #2 complete sentence. #3 Two sentences that could have been separated by other means instead of a comma. #4 Correct punctuation. When you have a subordinate clause, you use a comma.
