A deductive argument is _____ when it is valid and all its premises are actually true.

### Why this is right **Sound** is the term for a deductive argument that is valid and has true premises. Both conditions matter: correct reasoning cannot compensate for a false premise. ### The concept Validity concerns whether the conclusion follows from the premises. Soundness adds the factual question of whether every premise is true. For example, an argument can be valid but unsound if it begins with a false generalization. An invalid argument cannot be sound because it fails the logical condition built into soundness. ### Terms - **Deductive argument**: Reasoning that presents its premises as guaranteeing the conclusion. - **Valid**: Having a form that cannot combine true premises with a false conclusion. - **Sound**: Valid and based on premises that are all true. ### Remember Soundness requires two checks: valid reasoning and true premises.
