Question

4. The following is an argument meant to justify that, in fact, the Earth is not flat. "If the Earth were flat, then it would have edges that you could fall off. The Earth does not have edges that you can fall off. Thus, the Earth is not flat." A. true B. false

Answer 1

TRUE

The justification is valid - the Earth doesn't have edges, therefore is not flat. It's not a 'good' argument, but it is valid.
