If the density of a wood sample is less than 400 kg/m ³, then it is classified as low-density. If a wood sample is classified as low-density, then it is unsuitable for structural applications requiring high strength. Therefore, if a wood sample is suitable for high-strength structural applications, its density must be at least 400 kg/m ³.
Which one of the following arguments follows the same pattern of reasoning as the argument above?
