Explanation:

The line in the prologue of Romeo and Juliet that says, 'From forth the fatal loins of these two foes, A pair of star-cross'd lovers take their life,' foreshadows the tragic ending of the play. The audience can understand why Romeo and Juliet kill themselves because their families, the Montagues and the Capulets, are enemies, and their love is forbidden.
