Option 1 -> This describes comic storytelling, not humorous storytelling - the passage explicitly states comic storytellers announce the story is funny beforehand.
Option 2 -> The passage directly states "The humorous story is told gravely, with the teller attempting to conceal the humor" - this is the defining characteristic of humorous storytelling.
Option 3 -> Humorous stories do the opposite - the storyteller "drops it casually, with the pretense that he does not know it is a nub," rather than exaggerating.
Option 4 -> This describes comic storytelling - the passage says the comic storyteller "shouts it at you" and uses "italics and exclamation marks" for emphasis.
Hence, Option 2 -> The passage clearly distinguishes humorous stories from comic stories by emphasizing that humorous stories require a grave, deadpan delivery where the teller conceals rather than highlights the humor, making it "a high and delicate art" -> correct
