The reasoning above is most similar in its flawed reasoning to which one of the following?
- Every professional athlete exercises daily. Sarah is not a professional athlete. So Sarah does not exercise daily.
- If it rains, the grass surely gets wet. The grass is not wet at all. So it definitely did not rain today.
- All ordinary house cats have fur. Whiskers clearly has fur. So Whiskers must indeed be a cat of some kind.
- No valid argument has even one false premise. So no argument that has a false premise could ever turn out valid.
- Most diligent students study very hard. John happens to be a student. So John surely studies quite hard too.
