Decide whether the statement makes sense. Explain your reasoning.Your argument is sound, but it isn't valid.

What will be an ideal response?


Does not make sense. An argument is valid if its conclusion follows necessarily from its premises, regardless of the truth of its premises or conclusions. An argument is sound if it is valid and its premises are all true. By definition, if an argument is sound it is also valid. To put it another way, the set of sound arguments is a subset of the set of valid arguments. (Explanations will vary.)
