Read these lines: "There were no attendants at home; they had absconded to make merry in honour of the time. I had told them that I should not return until the morning, and had given them explicit orders not to stir from the house. These orders were sufficient, I well knew, to insure their immediate disappearance, one and all, as soon as my back was turned." What do the quoted lines reveal about the speaker?

1. The order given was that nobody should stir from the house. 2. The result was that everyone left, which is the exact opposite of the order. 3. The words I well knew show the speaker expected that result before he gave the order. 4. An order given in order to produce its own opposite is a piece of planning, not an accident. 5. So option C states what the lines reveal. 6. Option B is ruled out by I well knew, which removes any surprise. 7. Options A and D describe a trust and a dismissal that the quoted lines contradict. _Source: Edgar Allan Poe, The Cask of Amontillado, public domain_
