Statements: No pen is pencil. All pencils are blue. Conclusions: I. Some pens are blue. II. No pen is blue.
Correct answer: D. Neither follows
- A. Only I follows
- B. Only II follows
- C. Both I and II follow
- D. Neither follows
Explanation
The statements establish that the set of "pens" and the set of "pencils" are separate. While all pencils are blue, this gives no information about whether pens can or cannot be blue. Both conclusions are possible, but neither is definitively proven by the statements.
