Final answer:
The referenced action of Juliet asking the Nurse to pull up the ladder is not found in Shakespeare's play 'Romeo and Juliet'. The Nurse does aid Juliet, but there is no scene where Juliet requests the ladder to be pulled up.
Step-by-step explanation:
The question appears to be based on a misunderstanding as it references Juliet asking the Nurse to pull up the ladder in the play Romeo and Juliet by William Shakespeare. However, this specific event does not occur in the play. The character of the Nurse in Romeo and Juliet does assist Juliet by acting as a go-between for her and Romeo and by helping to arrange their secret marriage. If this were an actual scene, it might symbolize Juliet's desire to prevent further secret visits from Romeo, indicating that their relationship has reached a turning point. But it's important to clarify that this action does not take place in Shakespeare's play.
