Question

part b
what is the authors purpose for using the figurative language in part a?
to encourage readers to agree with an idea
to set the mood for the conclusion of the selection
to help readers understand a concept
to establish the authors tone in the selection

Explanation:

Figurative language (like metaphors, similes, etc.) is often used to make abstract or complex concepts more accessible and understandable by relating them to familiar ideas or images. The other options: encouraging agreement is more about persuasive devices, setting mood for conclusion or establishing tone are less central to figurative language's primary educational/ explanatory role. So the purpose of figurative language here is to help readers understand a concept.

Answer:

to help readers understand a concept
