Identify the sentence that is a metaphor.

• A. The rain fell gently.
• B. Time is a thief.
• C. He runs fast.
• D. The room was loud.

Answer: (B)

Metaphor is when you describe something by saying it is something else, creating a direct image without using like or as. Time is a thief does exactly that by naming time as a thief, which paints the idea that time takes moments away from us. This direct equivalence gives a strong, vivid image of time's impact. The other sentences describe actions or states in straightforward terms, not as symbolic identity: rain falling is a literal event, he runs fast is about speed, and the room was loud describes condition. So this sentence is the metaphor.
