Answer:
One way for the play to end favorably would be if Romeo had received the letter that Friar sent him. That way, he would know that Juliet was alive and would find her so they could live together.
Step-by-step explanation:
As you may already know, "Romeo and Juliet" is a play that tells the story of forbidden love between Romeo and Juliet, who are the children of two enemy families and can not be together. However, Romeo and Juliet were married in secret, without their families knowing.
However, after Romeo commits a crime in the city and needs to flee in haste, Juliet's family wants to marry her with another man, since they do not know that she is married. In this case, the one Friar, a friend of Romeo, has a plan for the couple to be able to stay together. This plan takes place in the last act of the play and includes Juliet pretending she died, while waiting for Romeo to come and get her, so that they can escape together. Meanwhile, Friar will write a letter to Romeo, explaining the whole plan so that he can meet Juliet. However, Romeo receives the news that Juliet has died, before receiving the letter from Friar. He returns to the city to confirm this and when he sees that Juliet is dead, he causes his own death. When Juliet sees that Romeo has died, she also causes her own death.
All of this would have been avoided if Romeo had received the letter, causing the play to end happily and favorably.
