It 's not because it 's post - apocalyptic because that 's what drew me to it . Ordinarily , I would not keep reading such a depressing book . McCarthy did a excellent job of taking me from one emotional extreme to the other , however .

Question: What may the author achieve with the book ?
Answer: None of the above choices .Every page in it made you feel nothing but sadness .The events that caused the apocalypse were detailed excellently .It caused the reader 's feeling to go through a rollercoaster .
