Answer:
to engage the audience in the tragic story
Step-by-step explanation:
This line, in the prologue of "Romeo and Juliet" is an example of foreshadowing, a literary technique where the writer goes on to hint about an important situation that will occur in history. In the case of this specific line, Shakespeare used foreshadowing to show the audience that this story was a tragedy, would not have a happy ending, and that love would not prevail. Shakespeare's intention with this was to make the audience moved and curious about the events that would be told in the story.
