Answer:
Mrs. Linde's desire to work to support her family demonstrates the theme "making sacrifices to support others is worth it."
Mrs. Linde's view of her past decisions demonstrates the theme "a lack of love and family can make one feel purposeless"
Step-by-step explanation:
Mrs. Linde married her husband Torvald due to her condition where she had to take care of a sick mother and two siblings. So, when she asked Krogstad to work together and be together, she demonstrates that she is finally ready to let go of her dependence on her husband. She would instead work on her own self and be who she needs to be first and then think about others.
