C. He becomes increasingly wary of his ability to scientifically defy morality.
1. Assuming that the underlined words are 'Carl Sandburg,' the correct answer is A. simple subject. Although you may be led to believe this is a complete subject (because it consists of more than one word), in fact, it is not. Carl Sandburg is the name and the surname of one person, which is why it is considered to be a simple, rather than a complete subject.
2. Assuming that the underlined words are '<span>served as a soldier during the Spanish-American War,' the correct answer is D. complete predicate. As you can see, these words include the simple verb served, as well as all other words which modify, or describe that verb. This is why this is complete, rather than a simple predicate. Simple predicate would be only the word served.
3. Assuming that the underlined words are 'would influence,' the correct answer is B. simple predicate. Similarly to the first sentence, you may be led to believe this is complete because there are more than one word in the phrase. However, the verb phrase would influence is considered to be one entity given that it is only a particular tense of that verb. Even if it said 'had been influencing' instead of 'would influence,' it would still be a simple predicate.</span>
In my opinion, the correct answer is <span>B) for Halloween // is decorated</span>. Adverb phrases are extended adverbs or phrases that function like adverbs, modifying the sentences' predicates. They tell us how, when, where, why the verb action is performed. In this case, the predicate is is decorated. We can ask the mental question: why or what for is the house decorated? The answer to this question would be for Halloween. And that is our adverb phrase. It shouldn't be confused with an adjective phrase "down the street", which describes the subject "the house".
The correct answer among all the other choices is "He is savage and brutal like a wild animal." This is what can be inferred about the Cyclops. Thank you for posting your question. I hope that this answer helped you. Let me know if you need more help.
