Identify the expression that is a metaphor.

• A. She runs like the wind
• B. He is a lion in battle
• C. He fights like a warrior
• D. She is Janis Joplin when she gets on stage

Answer: (D)

The expression that qualifies as a metaphor is one that makes an implicit comparison between two unlike things without using "like" or "as." In the case of the chosen expression, stating "She is Janis Joplin when she gets on stage" suggests that the person embodies the qualities or characteristics associated with Janis Joplin, such as being passionate, emotional, or powerful in her performance. This comparison allows for a deeper understanding of her stage presence by linking it to a well-known figure, enhancing the imagery and depth of the description.

The other expressions utilize similes or comparisons formulated with "like" or "as," which clearly identify the subject while making a comparison rather than asserting that one thing is another.
