The answer to this will be despairing
disrespectfulness
In the play the word is used when Keller says, "You be quiet! I’m badgered enough here by females without your impudence." The first trick to identifying a word's definition using context clues is to decide if the word is used in a positive way or a negative way. After reading Keller's statement, we can tell he is frustrated and annoyed, so he is not going to be talking in a positive way. This eliminates the first two options immediately. Disrespectfulness is your answer.
