Final answer:
The sentence 'Miriam, with her husband, owns a small business.' is a complete sentence because it has a subject, a verb, and expresses a complete thought.
Step-by-step explanation:
The question asks whether the sentence '"Miriam, with her husband, owns a small business." is a fragment or a complete sentence. This is a complete sentence because it has both a subject ('Miriam, with her husband') and a verb ('owns'), and it expresses a complete thought about Miriam and her husband owning a business.
A sentence fragment is a group of words that lacks one of these components and does not stand alone as a complete thought; an example would be 'Although income grew' from the provided reference.
