The prepositional phrase is “with the play”.
This is because a prepositional phrase begins with a preposition and is not essential in creating a complete sentence; instead it adds details.
With is a preposition, so with the play is a prepositional phrase. “She was bored” is still a meaningful sentence without the prepositional phrase, so we know that our answer is correct.
Hope this helps!
There should be a comma after “failures”. hope that helped! :)
