Unclear question. However, I provided a brief about a verb and clause.
<u>Explanation:</u>
In the English language, a verb refers to words that help describes an action done by a person or thing (the subject), or the state of the subject of a sentence. A clause other hand is the smallest grammatical unit that can express a complete thought in a sentence. Hence, the verb clause is a type of clause that acts as an independent clause in a sentence.
For example, the sentence; "The boys are trying very hard."
Answer:
Option C: The real tree is more detailed and smells fresher than the plastic trees that line the streets.
Explanation:
The entire story talks about the superiority, beauty and realness of the real trees in contrast with the inferiority and artificiality of the plastic trees. So the main theme of the story is summed up in option C, i.e. "The real tree is more detailed and smells fresher than the plastic trees that line the streets."
Option A is not correct because this idea does not run throughout the story; it is mentioned in just one line and is just cause of the disappearance of real trees.
Option B is incorrect because, it is just an incident in the story not a theme or idea of the whole story.
Option D is incorrect because it is part of the setting of the story with no theme in it.
