Final answer:
Aunt Alexandra in 'To Kill a Mockingbird' wants Atticus to forbid Calpurnia from taking Scout and Jem to her church due to her racial and social prejudices.
Step-by-step explanation:
In To Kill a Mockingbird, when Alexandra discovers that the children have gone to church with Calpurnia, she expresses her disapproval and wants Atticus to stop allowing Calpurnia to bring the children to her church.
