In a syllogism, what type of reasoning is being used?

• A. Inductive reasoning
• B. Deductive reasoning
• C. Abductive reasoning
• D. Comparative reasoning

Answer: (B)

In logic, a syllogism is a form of reasoning in which a conclusion is drawn from two premises that are generally assumed to be true. This process relies on deductive reasoning, which starts with a general statement or hypothesis and examines the possibilities to reach a specific, logical conclusion. In a syllogism, the premises provide a framework that guarantees the truth of the conclusion if the premises are true.

For instance, if we have the premises "All humans are mortal" and "Socrates is a human," deductive reasoning leads us to the inevitable conclusion that "Socrates is mortal." This structure emphasizes that the conclusion is a necessary result of the premises given, which is the hallmark of deductive reasoning.

Inductive reasoning, by contrast, involves drawing generalized conclusions from specific examples but does not guarantee the truth of the conclusion in the same way that deduction does. Abductive reasoning focuses on forming the best explanation based on available evidence, while comparative reasoning involves evaluating two or more items against each other. These reasoning types do not align with the fundamental mechanics of a syllogism, which is solely rooted in deductive reasoning.
