Final answer:
The statement about a firm's resources and capacities is true; resources are the inputs for production while capacities are a firm's abilities to use these resources. The comparative advantage stems from various factors and not just natural elements. Capacities contribute to a firm's unique advantages.
Step-by-step explanation:
The statement that a firm's resources and capacities are the unique skills and assets it possesses is true. Resources include all of the inputs needed for production, such as physical materials, labor, technology, and capital. Capacities, on the other hand, refer to the firm's ability to use these resources efficiently, which involves the unique skills, processes, and capabilities that a firm has developed. Comparative advantage, however, is not exclusively derived from natural elements like climate and mineral deposits. It can stem from a range of factors including worker education levels, technological expertise, specialized knowledge, economies of scale, and other productivity differentiators between economies. Therefore, the source of comparative advantage is multifaceted and goes beyond just natural elements.
