Answer:
Predict that Romeo and Juliet do not survive at the end of the play.
Explanation:
The prologue of the play is the short sonnet before Act 1, Scene 1 of the play. Shakespeare's prologues tended to give "spoilers" for the play to intrigue the audience.
Information in the Prologue
We can tell what the audience can understand from the prologue by reading it ourselves. While reading we can point out specific, important lines.
Line six states, "A pair of star-crossed lovers take their life." Later in the prologue, Line 8 says, "Doth, with their death..."
Inferences
Now, we can figure out what inferences can be made with the information we pointed out in the prologue. In multiple lines, Shakespeare talks about star-crossed lovers dying. The audience can predict that Romeo and Juliet will not survive. Most of the audience knows that Romeo and Juliet are the star-crossed lovers, so they can infer that neither of them will survive.
