Statements:
Some stars are planets.
Some planets are moons.
Conclusions:
I. Some moons are stars.
II. All planets being stars is a possibility.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1
Answer: Only Conclusion II follows
Quick breakdown:
Statements:
- Some stars are planets (I-type)
- Some planets are moons (I-type)
Checking Conclusion I: 'Some moons are stars'
This would require combining two 'Some' (I-type) statements. Two particular premises never yield a valid conclusion in syllogism — the classic rule: 'I + I → No conclusion.'
❌ Does NOT follow
Checking Conclusion II: 'All planets being stars is a possibility'
Since the statement only says 'Some stars are planets' (not 'No stars are planets' or any statement ruling out overlap), there's no contradiction if all planets turned out to be stars.
✅ This IS a valid possibility
