Passage Summary: A veteran sales manager argues that since naturally gifted top-sellers are rare, the best way for a company to get elite performance is to provide their staff with excellent management.

Conclusion: Companies should focus their efforts on hiring and developing high-quality sales managers.

Reasoning: Natural superstar salespeople are extremely difficult to find, but many average salespeople can reach superstar levels of performance if they are guided by a good manager.

Analysis: This argument presents a problem—the scarcity of natural talent—and offers a viable alternative solution—the influence of good management. To logically complete the argument, we need a recommendation that acts on this solution. Since the manager establishes that a good manager is the 'X-factor' that turns regular employees into superstars, the most sensible business advice is to prioritize the quality of those managers. Look for an answer that emphasizes investing in management rather than just hunting for rare 'natural' stars.
