Answer:
Establish a concept and emphasize a particular idea.
Step-by-step explanation:
A nonfiction text is one that presents facts in a precise or subjective way, but its main objective is to establish concepts, emphasize ideas, expose situations, clarify proposals, create a visual, among others.
As the nonfiction text is committed to passing on a reality, many people may believe that the use of figurative language should not be used in this type of text. However, figurative language can be very efficient, when the author of a nonfiction text uses it to establish a concept and emphasize a specific idea. This is because figurative language can create comparisons and expressions that facilitate reading and understanding, in these two aspects.
