Question

read the sentence. \we can put this vacant lot to good use by making it a city park,\ said the mayor. what does the word vacant mean in the sentence? empty and unused dark and hidden new and exciting busy and popular

Explanation:

The context of the sentence is about using a lot. If it's "vacant", it means it's not occupied or being used. "Empty and unused" fits this context. "Dark and hidden" doesn't relate to the idea of using the lot. "New and exciting" and "busy and popular" don't match the concept of a lot that needs to be put to use as they imply it's already in a certain state (new/exciting or busy/popular) rather than being available (vacant) for use.

Answer:

empty and unused
