What are the three types of conflict in "The Pit and the Pendulum"?

The most
obvious general conflict is that the prisoner (the narrator) is being imprisoned and tortured
during the Spanish Inquisition.

After being unconcious for a period of time,
he awakes to find himself in total darkness. He eventually stands and carefully navigates around
the outer walls, finally realizing how close he comes to falling into the steaming pit in the
center of the room. He survives this conflict and discovers something to eat and drink, which
revives him somewhat.

Surviving the pit, he reflects on two conflicting ways
of death: by physical torture or by "moral" (mental) torture. He determines that the
Inquisition has selected the moral alternative.

Once again he eats and
drinks, but he soon passes out and determines it is from the drug-laced food. He awakes to find
himself strapped to a fixed object and, staring upward, believes that he is watching the ceiling
painting moving. It is actually a large scythe that is slowly descending and moving from side to
side. As it comes closer, he notices the sharpness of the object and finally sees that it will
eventually reach him. How he will escape becomes his next dilemma. The rats that scramble around
him will also save him when he coats the strap with food and watches them eat through his
binding. He evades the pendulum just as it is about to strike.

Thinking
freedom is close at hand, he finds that the walls are now closing in upon him and that the only
way out is into the pit. But suddenly the walls recede, and the prisoner is saved by French
troops who have liberated the city.
