Even though you didn't italicize anything in this sentence, I managed to find the exercise on the Internet - the italicized part is <em>won. </em>The correct answer is simple predicate. A simple predicate is usually just one word - a predicate, a verb without objects and adverbs around it. If the part <em>won two first-place ribbons </em>was italicized, then it would be a complete predicate. <em>Stephen </em>is simple subject in this sentence, and at the same time complete subject as well. There are no predicate adjectives in the sentence above.<em> </em>
