Statements: All pens are blue. Some blue things are books. Conclusions: I. Some pens are books. II. Some books are blue
Correct answer: B. Only II
- A. Only I
- B. Only II
- C. Both
- D. None
Explanation
To determine the validity of the conclusions, analyze the logical relationships in the statements: 'All pens are blue' implies that every pen is a blue object, but it does not connect pens directly to books. The statement 'Some blue things are books' confirms that there is an overlap between blue objects and books, thereby validating Conclusion II. However, this does not imply that any pens are books, making Conclusion I incorrect. Therefore, only Conclusion II is supported by the given information, making Option B the correct choice.
