Passage Summary: The president wants to train managers in time management because the most efficient managers are already good at it, assuming this training will boost productivity.

Conclusion: The company should provide time management seminars to middle-level managers to increase overall productivity.

Reasoning: Consultants have noted that, generally, the managers who are most efficient also possess superior time management skills.

Analysis: This argument suffers from a classic correlation-versus-causation flaw: just because efficient managers happen to have good time management skills doesn't mean those skills caused their efficiency, or that teaching those skills to others will replicate that success. Since this is a 'Weaken EXCEPT' question, four options will attack this link—perhaps by suggesting the training is ineffective, that middle managers already have these skills, or that efficiency is driven by other factors. The correct answer will be the one that either supports the recommendation or is simply irrelevant to its success.
