Question

What is the defining direction of logical flow in deductive reasoning?

Answer

From the general to the specific. It starts with a broad premise and applies it to a specific case to draw a conclusion.

Question

How does inductive reasoning differ from deductive reasoning in its starting point and goal?

Answer

Inductive reasoning moves from specific observations to a general conclusion (like forming a hypothesis). Deduction does the opposite.

Question

Identify the reasoning type in this classic example: "All humans are mortal. Socrates is human. Therefore, Socrates is mortal."

Answer

Deductive reasoning. It applies a general rule ("all humans are mortal") to a specific case (Socrates) to reach a certain conclusion.

Question

In science, what is the typical role of deductive reasoning?

Answer

To make specific, testable predictions from a general theory or hypothesis. (e.g., If Einstein's general theory of relativity is true, then light should bend around the sun).

Question

True or False: A deductive argument can guarantee a true conclusion if its logic is valid.

Answer

False. Validity only means the conclusion follows logically from the premises. For the conclusion to be true, the premises must also be true. (Valid + True Premises = Sound Conclusion).
