At a team meeting, the manager said, “Since we didn't air the TV ad during prime time, foot traffic is bound to be low.” But the mall was packed that weekend because a large street fair was held next door. Which evaluation is most accurate?

Answer: B

• AThe manager's reasoning is not flawed; the ad is the main reason for attracting customers.✗ This option treats the ad as the sole cause and overlooks other possible reasons for the increase in foot traffic, representing an oversimplification of causality.
• BThe manager's reasoning commits the fallacy of denying the antecedent: not airing the ad doesn't necessarily mean foot traffic will be low.✓ Correct. The manager treats airing the ad as the only condition for high foot traffic, concluding low traffic from not airing it, ignoring other factors like the street fair that can also bring in crowds.
• CThe manager's statement implies the fallacy of affirming the consequent, because foot traffic increased, so the ad must have worked.✗ This option confuses two logical fallacies. The manager's argument is from not airing the ad to low foot traffic, which is denying the antecedent, not affirming the consequent by inferring the cause from the effect.
• DThe manager's reasoning is actually rigorous, because the claim that foot traffic stays low without the ad needs facts to refute it.✗ This option mistakes the need for factual refutation as a reason for sound reasoning, but whether reasoning is rigorous depends on logical structure, and the manager's structure is inherently flawed.
