In the question, some statements are given, followed by three conclusions I, II and III. You have to consider the statements to be true, even if they seem to be at variance from commonly known facts. You have to decide which of the given conclusions, if any, follow from the given statements. Indicate your answer.
Statements :
Only few papers are books.
Some books are e-books.
All e-books are magazines.
Conclusions :
I. No book is magazine.
II. Some magazines are paper.
III. No magazine is paper.

Correct option is B

Statements:

1. Only few papers are books: This implies that some papers are books, but not all.
2. Some books are e-books: This means there is an overlap between books and e-books.
3. All e-books are magazines: This means e-books are entirely contained within magazines.

Conclusions:

1. No book is magazine: This cannot be concluded. Some books are e-books, and all e-books are magazines. Therefore, some books are magazines. Conclusion I does not follow.

2. Some magazines are paper: The statements do not establish any relationship between papers and magazines. Thus, Conclusion II does not follow.

3. No magazine is paper: Since the relationship between papers and magazines is undefined, Conclusion III does not follow either.

However, Conclusions II and III form a complementary pair. They are mutually exclusive and together exhaust all possibilities regarding the relationship between magazines and papers (either "some magazines are paper" or "no magazine is paper"). Therefore, one of these conclusions must be true.

Final Answer:

B: Either II or III follows.
