Ch.21.3.2 What literary devices are boing employed through this comparison and to what end?

I'm not sure exactly what you're taling about. If the question you're referring to relates to the quote (simile), it is being employed to describe the atmosphere in the town of Maycomb. From the quote we come to understand how the summer's events have affected to residents of Maycomb. Smoke in a dark room would be stiffling and oppressive, as were the effects of the trial preparations and actions of Maycomb's community.

The whale question is like this

As they wait for the verdict ,Scout gets fa feeling that the courtroom is like that "deserted,waitir empty street " where "every wood door in the neighborhood woas shut as tight as the door of the Radley place ." What other scene in the book is being reffered to ? What literary devices are being employed through this cmparison and tho what end ?

Please answer .
