Answer :
The question requires the indication of the sources of the narrator's perspective, which are as follows:
Passage 1 notes that the narrator expressed "a sense of insufferable gloom" to indicate that the narrator's perspective is obtained in the story.
- The knowledge came to the narrator immediately after the building came into view. Observation is when the narrator gains perspective in the story.
Passage 2, where the narrator discusses his intimate friends, shows that the narrator obtains knowledge from the past.
- Background information helps the narrator to know from the past.
The third passage shows that the narrator is making an inference. After observing the vault or tunnel, the narrator concludes that the design is conveying an idea.
- An inference's basis is on some evidence. In addition, an inference can also be arrived at with reasoning based on observation and background information.
Thus, the narrator's inference is a conclusion arrived after observation or based on background information.
