Final answer:
In the beginning of a personal narrative, authors use a strong introduction as a 'hook' to engage readers and develop their main ideas.
Step-by-step explanation:
In the beginning of a personal narrative, authors typically use a strong introduction to help develop their main ideas. This introduction serves as a 'hook' to engage readers and includes vivid details or a relatable anecdote. The opening strategy should be brief, usually not more than two paragraphs, and should introduce the main characters, setting, and conflict of the story. It sets the stage for the events that will unfold and helps establish the main idea that the author wants to convey.
