The correct answer is the first one: Melville is building a mood of suspense.
Long before Ahab appears in the story, there is an atmosphere of mystery about the captain of the ship. The owners call in the crew in while Ahab is absent. Ishmael is told that Ahab is a man of few words but deep meaning; from the first moment, it is clear that the captain has a complicated personality. He is an "ungodly, god-like" man who has attended colleges as well as he has been among cannibals. Ahab is ungodly because he refuses to submit to a higher power. He does not worship or even acknowledge that there are forces beyond himself. Ahab is god-like in the sense that he represents a higher power; perhaps he even wants to be considered as a God.
The mystery is deepened as Ahab remains in his cabin through the first days of the trip. Ishmael grows anxious, checking the area outside the captain's cabin whenever the narrator goes on watch. When Ahab finally appears, in this chapter 28, he is an imposing figure whose haunted look sends shivers Ishmael's spine.
Answer:
I believe the best answers are:
blank 1 -- C) that has
blank 2 -- A) NO CHANGE
Explanation:
The original sentence, "...the US government has the power to take custody of land when having historical significance or great natural beauty" is a bit ambiguous. Who has historical significance? We assume it is the land. But, in the way it is phrased, it could also be the government. To eliminate such ambiguity, the best option is letter C) that has. It will help determine a certain land can be taken. What land? The one that has historical significance.
As for the sentence, "The designation of a territory as a national park, national monument, or other types of protected area can limit activities," I don't see any reasons for changes. Especially because of the word "other", which needs to be completed by a plural noun - eliminating options B and C. Letter D wouldn't be incorrect, but the transformation of "protected area" into an adjective for "types" is unnecessary. The sentence is perfect the way it is and, therefore, needs NO CHANGE.
Participles are verb forms which look like verbs + suffix -ing. So having that in mind, the participle in the sentence above is the word standing.
Participles function either as adverbs (when they modify verbs), or as adjectives (when they modify nouns). In this case, the participle acts as an adjective, modifying the word child.
