Statements:
1. Some books are pens.
2. Some pens are erasers.
Conclusions:
I. Some books are erasers.
II. No book is an eraser.
Which conclusion(s) logically follow?
Explanation:
There is no direct relationship established between books and erasers. They might overlap, or they might not. Therefore, neither conclusion can be definitively drawn individually. However, they form a complementary pair (Some A are B / No A is B), meaning one of them must be true. Hence, 'Either I or II follows' is the correct logical deduction. (Mapped to option C for this specific question).
