How does the author use structure to convey a sense of tension in the passage? by detailing the development of the conflict between the characters
by providing a clear resolution to the conflict between the characters
by foreshadowing the dentist's thoughts and experiences with the mayor
by highlighting a contrast between the mayor's anxiety and his established power

I want to say that the answer is, A. By detailing the development of the conflict between the characters.

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.
