1. Only I follows
2. Only II follows
3. Both follow
4. Neither follows

Correct answer: Only I follows

Solution

Conclusion I is possible because pens are a subset of pencils, and some pencils are erasers; there is no contradiction in some pens being erasers. Conclusion II does not definitely follow because no direct relation between pens and sharpeners is given. Hence, only I follows.
