Some books are novels. All novels are stories. Which conclusion follows?
- A. All books are stories
- B. Some books are stories
- C. No book is a story
- D. All stories are books
Explanation
The books that are novels must also be stories, which guarantees that at least some books are stories, but nothing is known about the remaining books. A conclusion beginning with all cannot follow from a premise beginning with some. The reversal in the last option is invalid for the same reason.
