Which of the following excerpts from the short story "the tell-tale heart" by edgar allan poe best demonstrates the unreliability of the narrator? • you should have seen how wisely i proceeded-with what caution-with what foresight-with what dissimulation i went to work! • i heard many things in hell. how, then, am i mad? hearten! and observe how healthily-how calmly i can tell you the whole story. • and then, when i had made an opening sufficient for my head, i put in a dark lantern, all closed, closed, that no light shine out, and then thrust in my head. • oh you would have laughed to see how cunningly i thrust it in! i moved it slowly-very, very slowly, so that i might not disturb the old mans sleep.
