A survey of readers of a fitness magazine found that most exercise daily; the author concludes that most citizens exercise daily. The argument is flawed because:
Athe sample group was too elderly
Bthe sample is unrepresentative of all citizens
Cthe term exercise was left undefined
Dthe survey responses were anonymous
Answer & Solution
Correct answer: B. the sample is unrepresentative of all citizens
Fitness-magazine readers are atypically health-focused, so they cannot represent the general population.
