Which is a way the reader can tell Claudia is growing up? A. her calling Jamie a blabbermouth for telling Mrs. Frankweiler about
the museum B. her correcting Jamie for calling people dead rather than deceased C. her agreeing with Jamie when he suggests she is not to correct his grammar in every conversation D. her following Jamie's advice to ask Mrs. Frankweiler more about the Angel statue
Even though I don't know the article I can tell that the answer is D:her following Jamie's advice to ask Mrs. Frankweiler more about the Angel statue because Claudia asked Jamie advice and that's evidence that Claudia is growing up and going to learn something new from Jamie's advice
If this is a personal question then I would say yes it is nobler to die with you're integrity then to live with compromised principles that harm others. Its honestly you're own opinion.
