Statements: Some books are pens. No pen is pencil. Conclusions: Some books are pencils. No book is pencil.

Only conclusion I follows
Only conclusion II follows
Either I or II follows
Neither I nor II follows
Both I and II follow

Correct Answer: Either I or II follows

Explanation:

As discussed above, the conclusion must be particular negative and should not contain the middle term. So, it follows that 'Some books are not pencils'. However, I and II involve only the extreme terms and form a complementary pair. Thus, either I or II follows.
