Answer:
"My uncle chooses to shop locally"
Step-by-step explanation:
If something is independent, then it can be by itself. If you are independent, you don't need a lot of help from others. Same thing with independent clauses. Independent clauses can stand alone as a full sentence. "My uncle chooses to shop locally" tells us everything so it is a full sentence. My uncle is the subject, and the predicate is "chooses to shop locally" That tells us what he's doing. It is a full sentence with all the needed information.
