by influencing how the reader feels by describing what happened
Step-by-step explanation:
An author can provide more details to the reader by describing, within his narrative, in a detailed way the factors and elements that led a given situation to happen, or how that situation happened. With this the author provides a description, literally, detailed about an important point in his narrative. This allows the reader to have a full understanding of what is happening in the narrative, triggering emotions and feelings related to the details that the author provided.
