Question(s)?

I was looking through my Study Guide and I found that I am missing things all the way to Act II. If you guys could help me, that would be great. I need help with Scene 4, Scene 5, and Scene 6.

Scene 4

6. After Mercutio leaves the scene before Romeo speaks to the nurse, does the Nurse revert to character?

7. What is the atmosphere in this scene?

Scene 5

6. Explain the Nurse's ribald humor as the scene ends?

Scene 6

1. What does the Friar warn Romeo about?

4. What forboding is in this scene?

5. What emotional poles do we see in this scene?

6. What light imagery again enters this scene?

Sorry, that is a lot of questions. I don't remember going over that part of the study guide in class. Thank you for your help.
