Final answer:
The provided references do not specify a story titled "The Lighthouse Lamp"; thus, the number of characters in such a story cannot be determined.
Step-by-step explanation:
The question appears to be inquiring about the number of characters in a story involving a lighthouse lamp. However, the reference excerpts provided do not specify a story titled "The Lighthouse Lamp" and instead discuss visual art pieces by Edward Hopper and other unrelated textual excerpts.
Therefore, with the information provided, it is not possible to definitively answer how many characters are in the story "The Lighthouse Lamp" as the narrative itself is not included among the references.
