one last question what tone name would you give this

he unbuttoned his vest, unbuttoned his collar, loosened his tie and took off his coat. he never loosened a scrap of his clothing until he undressed at bedtime...... atticus put his hands in his pockets and as he returned to the jury...........(271)

the assignment is asking why did you pick this tone section, it saying mention the word choice, it is also asking to justifiy your self
