Statements:
1. Some books are pens.

I. Some books are erasers.
II. No book is an eraser.
Which conclusion(s) logically follow?
A. Only conclusion I follows
B. Either I or II follows
C. Both I and II follow

Solution (By JKExamLibrary)
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).

II. The company's previous smartphones were very expensive.
Which conclusion(s) logically follow?
Explanation:
Launching advanced AI features indicates an intent to attract people interested in such tech (Conclusion I). However, the statement provides no information about the pricing history of the company's previous phones (Conclusion II).
