What is meant by the value of using a metaphor in writing?

Using a metaphor in writing serves to illustrate complex ideas or emotions through comparison, making them more relatable and impactful for the reader. When you say something is "a light in the darkness," you create a vivid image that conveys hope or guidance in difficult times without stating it explicitly. This figurative language enriches the text by allowing readers to understand the significance of an idea or theme in a deeper way.

In this case, choosing the option that highlights a metaphor's role in illustrating why something is important or helpful captures its essential function in writing. Rather than providing a literal definition, metaphors enhance meaning and evoke imagery, fostering a connection between the reader and the text. By doing so, they make the writing more engaging and resonant.
