Option 1 -> Correct interpretation; "does not slur the nub" means doesn't minimize or pass over it lightly, which is confirmed by the passage stating he "shouts it at you" and "emphasizes the punchline."
Option 2 -> Contradicts the passage; the comic storyteller explicitly mentions and emphasizes the punchline, not avoids it.
Option 3 -> This describes the humorous storyteller who "drops it casually" and pretends not to know it's the nub, not the comic storyteller.
Option 4 -> Being "skillfully casual" is characteristic of the humorous storyteller, whereas the comic storyteller is deliberately emphatic and obvious.
Hence, Option 1 -> The phrase "does not slur the nub" literally means the comic storyteller doesn't gloss over or minimize the punchline. The passage immediately clarifies this by explaining that he "shouts it at you" and uses italics and exclamation marks to emphasize it, making the punchline unmistakably obvious rather than subtle -> correct
