Answer: D. Imitative yet fresh
Explanation:
Koch´s poem is a parody, meaning that it purposefully makes fun of something. In this case, the author mocks a serious composition by imitating its style or tone. "Variations on a Theme by William Carlos
Williams," as many other poems by Koch, used satire to express his disagreement with the idea of poetry being solemn and not suitable for humor. By using a similar structure and theme (having done something wrong and providing an excuse for it), Koch mocks "This is Just to Say," by William Carlos Williams. And to make it more clear, Koch makes his character a doctor, just like Williams, who was a poet in his free time after working in the hospital.
Predicate nominative is also popularly known as the predicate noun. It is a noun, a pronoun or any nominal that follows the linking verb and most of the time the form of the verb be. It links or completes the linking and change the name of the subject. It complements or completes the verb in the sentence. However, predicate nominative completes only linking verbs. Predicate nominative can be compound while some do not have one. Therefore in the sentence "Sugar is the main ingredient in taffy", the predicate nominative is "ingredient".
