Most of the poem "An Hymn to the Evening" concerns itself with giving praise to God for any personal virtue we have acquired. Its Christian message is not considered neoclassical and the model to which all other pastoral poetry should aspire. Hope this helps.
D. is wrong. It should be "One hero in the animation field is Mel Blanc, the voice behind many cartoon characters." because the information after Mel Blanc is not necessary to the sentence. It's just extra, so you need a comma.
