Final answer:
Run-on sentences combine multiple complete thoughts without proper punctuation, while fragments are incomplete sentences lacking a subject or a verb.
Explanation:
Run-on sentences occur when two or more complete sentences are not properly separated by punctuation. This mistake can lead to a lack of clarity and disrupt the flow of writing.
Fragments, on the other hand, are incomplete sentences that lack a subject or a verb and do not express a complete thought. It is important to recognize and correct both run-on sentences and fragments to improve the overall quality of writing.
