If a director wanted to make the story less depressing, they could cut out the ending in which they both commit suicide. This would greatly affect the message of the play. However, I am not sure if this is what you need.
I think its asking for what scenes in Romeo and Juliet and unnecessary but really, if you cut any scenes it will still affect the relationship between the characters as the audience will not seen them develop throughout the show
