Cereal advertisement: Fitness experts say that regular exercise is the most effective way to become physically fit, and studies have shown that adults who eat cereal every day exercise more regularly than adults who do not eat cereal. So by eating Fantastic Flakes every morning, you too will be on the most effective path to physical fitness. The argumentation in the advertisement is flawed in that it ['presumes, without providing justification, that Fantastic Flakes are more nutritious than other cereals', 'infers a cause from a mere correlation', 'draws a conclusion about all adults from a sample that is too small to be representative', 'infers that a given factor is the sole predictor of a result merely on the grounds that the factor has been shown to contribute to that result']
