Ok which of peter's lines shows that he is using personal experience to understand the reading?

the answer is true.

the international phonetic alphabet (a standardized system of phonetic symbols devised and maintained by the international phonetic association) is composed of one or more elements of two basic types, letters and diacritics.

the correct answer is: reveal gregor as an untidy individual.

in metamorphosis by franz kafka, gregor samsa is the main character, who one day wakes up as a bug, and the attitude he takes upon his transformation forces him to go deeper on his existence and the new features of his body.

in this excerpt the writer mentions a table full of collection textile samples, which gives us a hint about gregor being messy. later on the book we discover how he is a really untidy individual.
