Journalist: Recent studies have demonstrated that a regular smoker who has just smoked a cigarette will typically display significantly better short-term memory skills than a nonsmoker, whether or not the nonsmoker has also just smoked a cigarette for the purposes of the study.
Facts
Most of the time, smokers have better short-term memories than nonsmokers, after they’ve smoked a cigarette. And the advantage for the smokers usually lasts at least 8 hours.
Evaluation
Correct answers to must be false usually contradict a conditional rule or contradict an available inference. There’s no conditional here, so is there an available inference we can get by combining the two facts? It sound like for most regular smokers, if they smoke a cigarette every eight hours or less, they’ll indefinitely have better short term memory than nonsmokers.
Goal
Find an answer that contradicts the idea that smokers have a short-term memory advantage in most cases, after they’ve smoked a cig, and the advantage lasts for at least 8 hours.
