Final answer:
Lord Capulet instructs Lady Capulet to prepare Juliet for her arranged marriage to Paris, a key event in Shakespeare's 'Romeo and Juliet' that precipitates the play's tragic conclusion.
Step-by-step explanation:
The request to 'report Capulet's instruction to his wife' refers to a scene from William Shakespeare's Romeo and Juliet, where Lord Capulet gives specific instructions to Lady Capulet concerning the arranged marriage of their daughter, Juliet. In the play, Lord Capulet becomes angry with Juliet when she refuses to marry Paris and instructs Lady Capulet to prepare Juliet for the marriage, insisting that the wedding takes place as planned. This demand by Lord Capulet is critical to the plot as it leads to Juliet's desperate actions to avoid the marriage, ultimately resulting in the tragic ending of the play.
