<em>It's a Good Life </em>is a short science fiction/horror story written by American author Jerome Bixby.
Third-person point of view is used throughout the short story.
A point of view tells us the narrator's position in retelling the events and describing the characters. A third-person point of view shows us that the narrator is outside of the story. The narrator will use character's full names, as well as <em>he/she</em> and <em>his/her</em> pronouns when talking about characters.
You have to give us the context so we know what the story is about
If the phrase <em>of the land </em>is underlined, then it would be an adjective phrase. This is because the whole place belongs to the noun <em>beasts - </em>what kind of beasts? (Those) of the land.
You are describing what beasts are like, which means that you are using an adjective, not adverb.
