To help a reader understand the author's purpose, the following three aspects of a story are particularly impactful:
A. imagery - It creates vivid mental pictures and evokes emotions, helping readers grasp the themes and feelings the author intends to convey.
D. setting - The time and place of the story can provide context for the characters and events, revealing the author's perspective and intentions.
E. tone - The attitude or emotion conveyed in the writing helps the reader to interpret the author's purpose and the message being communicated.
While plot and repetition can also contribute to understanding, imagery, setting, and tone are more directly tied to the author's purpose.
