Statements: All wires are copper. Some copper is metal. Conclusions: I. Some wires are metal. II. All copper is wire
Correct answer: D. None
- A. Only I
- B. Only II
- C. Both
- D. None
Explanation
Based on the statements: 'All wires are copper' and 'Some copper is metal', we cannot definitively conclude that 'Some wires are metal' (Conclusion I) because the relationship between wires and metal is not directly stated. Similarly, 'All copper is wire' (Conclusion II) is incorrect as the statement only confirms that all wires are copper, not that all copper is wire. Therefore, neither conclusion logically follows from the given statements.
