Decide whether the statement makes sense. Explain your reasoning.The premises are true and the conclusion is true, so the argument must be valid.
What will be an ideal response?
Does not make sense. For an argument to be valid, its conclusion must follow necessarily from its premises. Just because the premises and the conclusion are true does not mean the conclusion follows necessarily from the premises. For example, consider the following argument:
Premise: Dogs bark.
Premise: Cats meow.
Conclusion: Pigs oink.
The premises and the conclusion are all true, but the conclusion has nothing to do with the premises. (Explanations will vary.)
