If no scientist is dishonest, and some teachers are scientists, which conclusion is valid?
Correct answer: A. Some teachers are not dishonest
- A. Some teachers are not dishonest
- B. No teacher is dishonest
- C. All teachers are scientists
- D. Some scientists are teachers only
Explanation
The teachers who are scientists must be honest, so at least some teachers are not dishonest, while the remaining teachers are unknown. Extending this to all teachers is the classic overreach. A some premise limits the conclusion to some, whatever the other premise says.
