The phrase that defines a sound argument is "a sensible and valid statement." It is important for an argument to be sensible, meaning it is logical and reasonable, and also valid, meaning that it is based on sound reasoning and evidence. To determine if an argument is sound, you should evaluate whether it has a clear and logical structure, supported by relevant facts and evidence, and avoids logical fallacies. It should also consider alternative perspectives and counterarguments. By critically analyzing the reasoning and evidence presented in the argument, you can determine if it is a sound argument.
