- Mount Everest is taller than Mount Kilimanjaro. No anthill is as tall as Mount Kilimanjaro. Therefore， Mount Everest is taller than any anthill.How would you describe the above example？（ ） A: N = not an argument B: A = an argument that is neither valid nor sound C: V = an argument that is valid but not sound D: B = an argument that is both valid and sound
- A<br/>valid argument must be a sound argument, but a sound argument is not<br/>necessarily a valid argument.
- Consider the following argument: “He is not a terrorist, so he must be a counterterrorist under cover.” Which of the following suppressed premises could be added to this argument to make it valid?
