Answer:
“the only unused space”
Explanation:
Context clues refer to the surrounding information of an unknown word in a text or a speech that helps us infer the meaning of that word. In the excerpt, the phrase “the only unused space” works as a context clue of the word “vacated” because it helps us infer that the term is an adjective used to refer to something (in this case, the plot) that is not being used, that is empty.
