D. A device used for listening to sounds from a distance.
Answer: (B)
Solution: Based on the context of the passage, it mentions “Joy gazed at the night sky through a powerful telescope” which indicates that the telescope is used to observe distant objects (stars and planets) in the night sky. This aligns with the definition of a telescope as “an instrument used to make distant objects appear larger and nearer.”
