Without the specific text from paragraph 53 of "Yesterday Was Beautiful" by Roald Dahl, I can only offer a general analysis based on Roald Dahl's thematic styles and character portrayals. If the description of Anna suggests qualities such as confidence or the ability to handle challenges, it may indicate she is strong and resourceful. Conversely, if she is portrayed in a way that highlights fragility or passivity, that would suggest she is weak and vulnerable.
To accurately determine which response best fits, please refer to the text of paragraph 53 or provide a brief description of how Anna is portrayed there.
