Answer:
Mr. Hendricks’s
Mrs. Hendricks’s
Audrey’s
Step-by-step explanation:
In the text above we have no reference to the narrator's thoughts or feelings, not even the grandparents', mentioned at the end of the text.
However, through reading we learn about the thoughts of some characters. First, we know the thoughts of Mr. and Mrs. Hendricks. It is possible to see their thinking through the passage "Since Mr. and Mrs. Hendricks thought that was a good idea, they helped her get ready"
Ahead, we come across the feelings of Mrs. Wills, during the passage "Mrs. Wills cried".
Last, but not least, we come across Audrey's thoughts, twice during the narrative. This first happens in the passage "Audrey imagined that it would entertain her if she got bored during her week on a cell block", later we have access to her thoughts in the passage "Audrey knew she was proud of her."
