I would say that these are the two thesis statements best for a literary analysis essay on recurring themes in Shakespeare's Romeo and Juliet:
1. In Romeo and Juliet, Shakespeare demonstrates that love comes in a variety of forms, be it romantic, familial, or between friends.
2. Shakespeare explores the struggle for identity through the character of Juliet in his play Romeo and Juliet.
The other theses aren't reoccurring in this play.
Just find two nonfiction texts, after you read them, write down a list of benefits for each text. then just sum it all up in a few sentences and you're done.
