Question

Statements: No book is a paper.
Some papers are pens.
Conclusions: I. Some books being pens is a possibility.
II. All pens being books is a possibility.

• A. if only conclusion I follows.
• B. if only conclusion II follows.
• C. if either conclusion I or conclusion II follows.
• D. if neither conclusion I nor conclusion II follows.
• E. if both conclusion I and conclusion II follow.

Answer 1

The correct option is A if only conclusion I follows.

Two cases are possible in this situation.

Some books being pen is a possibility in diagram 1.

All books can be pen but all pens can not be books.

Thus, some books being pens is possible in some cases but not always.

Hence, Option A is correct.
