The simple predicate (the simple verb) is "walked" -- and the complete predicate is "walked to the park."
In the sentence, "James walked to the park," the entire phrase "walked to the park" is the predicate. The predicate is the part of the sentence that contains the action or state of the subject, in this case, James. To determine the predicate, you can look for the verb in the sentence. In this case, the verb is "walked," which indicates an action performed by James. Since the phrase "to the park" describes where James walked, it is considered part of the predicate. Therefore, the complete predicate is "walked to the park."
