Answer:
The first-person point of view lets Poe give the reader an insider's view into the terror and agony of the imprisonment.
Step-by-step explanation:
The answer is that the first-person point of view in The Pit and the Pendulum gives the reader an insider's view into the terror and agony of the imprisonment because throughout the entire story it is like the reader is on the character's mind and the use of the pronoun "I" makes it more personal eventually making the reader feel what the main character is experiencing. The entire story is a vivid and detailed description of set imprisonment, the character's conclusions and thoughts of what he sees almost without a filter, other characters or dialogues are not taken into consideration but only the first-person point of view making the character's thoughts become or merge with our own.
