Passage Summary: Comedians use jokes to keep people interested and help them remember serious points; since professors want to do the same thing, they should probably use jokes too.

Conclusion: University professors should utilize humor in their lectures to effectively engage students and ensure their points are remembered.

Reasoning: Comedians successfully use humor to maintain audience attention and communicate serious ideas, and professors share these exact same educational goals.

Analysis: This argument relies on an analogy between stand-up comedy and academic lecturing. Since the stimulus establishes that humor is the specific 'means' by which comedians achieve their success, and then states that professors 'hope to achieve much the same,' the logical completion is to apply that same 'means' to the professors. We are looking for an answer that bridges the gap between the comedians' methods and the professors' objectives. It essentially suggests that if you want the same results, you should use the same tools.
