Hello. You did not inform the book to which the question refers, but according to the context it presents, we can see that it is the book "The Diary of Anne Frank."
Answer and Explanation:
The arrival of Mr. Dussel changes the installation of the other members of the secret annex in the available rooms. Space becomes more limited and the division of food and tasks becomes more complicated. Furthermore, Mr. Dussel is not used to living with so many people, nor is he used to having to deal with someone as young and as opinionated as Anne. Because of this, living with him becomes a challenge, since he is ungrateful, stressed and controlling, as he represses Anne as much as he can.
"The Diary of Anne Frank" presents the account of a Jewish girl, Anne, about the moments when she was hidden from Nazi violence, in addition to hiding so as not to be taken to concentration camps. Anne went into hiding with her family and other Jews, including Mr. Dussel, who joined the hiding place much later and presented problems of establishment, especially in relation to Anne.
