Answer
Brief Explanations:
A simple sentence consists of a single independent clause, which contains a subject and a predicate and expresses a complete thought. In the provided sentence, "the United States Flag Code" is the subject and "has provided advisory rules for displaying and handling the U.S. flag" is the predicate. The introductory phrase "Since 1923" is a prepositional phrase acting as an adverbial modifier, not a dependent clause, because it lacks its own subject and verb. Since there is only one independent clause and no subordinate clauses, it is classified as a simple sentence.
