Final answer:
Friar Laurence devises a scheme involving a sleeping potion to prevent Juliet's bigamy, with the outcome being the tragic deaths of both her and Romeo due to a miscommunication.
Step-by-step explanation:
Prevention of Bigamy in Romeo and Juliet
To prevent bigamy and help Juliet avoid marrying Paris after she has already secretly married Romeo, Friar Laurence devises a plan involving a sleeping potion. The potion will make Juliet appear dead, thus avoiding the wedding. The purpose of this plan is to allow Juliet to reunite with Romeo without being married to someone else. Tragically, the outcome of this scheme is a miscommunication that leads to the deaths of both young lovers. Romeo believes Juliet is truly dead and kills himself. Juliet, after waking and finding Romeo dead, also takes her own life. The plan, although well-intentioned, culminates in the tragic ending of the play, reinforcing the moral lesson about the destructive nature of hate and feuding.
