Concept:Syllogism: Determine which conclusion necessarily follows from given statements using logical reasoning.Explanation:Statement 1: Some books are pens.Statement 2: No pen is pencil.From these, the books that are pens are definitely not pencils. However, other books (not pens) may or may not be pencils. Thus, we cannot conclude that some books are pencils (I) because it is possible that no book is a pencil. Also, we cannot conclude that no book is a pencil (II) because some non-pen books could be pencils. Hence, neither conclusion follows.Answer:Neither I nor II follows.
