Statements: All actors are people. All people are humans. Conclusions: I. All actors are humans. II. All humans are actors.
Correct answer: A. Only I
- A. Only I
- B. Only II
- C. Both
- D. None
Explanation
The correct answer is Option A: Only I. This is because the logical deduction follows the transitive property: if all actors are people and all people are humans, then it logically follows that all actors are humans. Conclusion II, 'All humans are actors,' is incorrect because the initial statements do not suggest that all humans must be actors. There could be humans who are not actors, which means the converse does not hold. Thus, only conclusion I is valid.
