Show answer & explanation
Correct answer: C
Statements:
1. All threads are needles.
2. Some needles are brushes.
3. All needles are cupboards.
Evaluation of conclusions:
Conclusion I: Some brushes are cupboards — follows (True). Reason: Some needles are brushes, and all needles are cupboards; therefore the brushes that are needles are cupboards, so some brushes are cupboards.
Conclusion II: All threads are cupboards — follows (True). Reason: All threads are needles and all needles are cupboards, so every thread (being a needle) is a cupboard.
Conclusion III: All brushes are threads — does not follow (False). Reason: Only some needles are brushes and threads are a subset of needles; brushes may include items that are not threads, so we cannot conclude that every brush is a thread.
Final answer: Both Conclusion I and Conclusion II follow; Conclusion III does not. Therefore the correct choice is: Only I and II follow.
