At a review meeting, Xiao Li questions the basis for a new supplier's quotation. The supervisor says, 'Director Wang personally set this plan; he has been in procurement for twenty years. Just listen to him.' Xiao Li wants to continue discussing the plan itself. Which evaluation is the most accurate?

Answer: B

• ADirector Wang is experienced, so the plan is likely feasible; Xiao Li need not press further.✗ Incorrect. The belief that 'experienced therefore automatically correct' is the core misunderstanding of appeal to authority: seniority only increases credibility, not the need to verify the quotation's basis or to question conflicts of interest.
• BThe supervisor used Director Wang's status and experience in place of discussing the quotation's basis itself.✓ Correct. The supervisor answered 'who set it' rather than 'whether the quotation basis holds,' treating authority as the endpoint of reasoning; experience only adds credibility, not automatic correctness.
• CChallenging a leader publicly is disrespectful; Xiao Li should raise it privately first.✗ Incorrect. This confuses questioning the plan with offending the person, mixing the question's validity with the questioner's attitude; even if the manner could be discussed, the plan's basis still needs addressing.
• DIf other departments also use this supplier, Xiao Li need not question further.✗ Incorrect. Appeal to majority: other departments' use only shows its popularity or suitability for their contexts, not its fit for this department's needs and cost conditions.
