Answer:
It helps readers to understand what the meaning is behind different types of figurative language.
Step-by-step explanation:
Part of the definition of paraphrasing, given by Cambridge Dictionary is "to repeat something read or spoken using different words."
As speakers, we always select the words we know, specially when we find the ones we don't. Poetry sometimes uses complex language or rhetorical devices, which can make it difficult to understand. Rephrasing helps the reader understand the meaning by using words that are closer to the speaker (because he chooses the words) and not some words or images to which the reader is not related.
