Final answer:
Canada exports more on a per capita basis than both Japan and the United States because smaller economies like Canada are generally more engaged in international trade than the larger economies of Japan and the U.S.
Step-by-step explanation:
A student has asked how Canada's per capita exports compare with those of the United States and Japan. Considering recent economic data and the nature of international trade, it becomes clear that smaller economies often have a higher export per GDP ratio than larger economies. For example, the United States and Japan, which are large economies with the ability to maintain a significant division of labor within their national borders, tend to have lower exports in proportion to their economy compared to global averages. On the other hand, medium and smaller economies, such as Canada, Belgium, and Korea, must engage more actively in international trade to take advantage of specialization and economies of scale.
Given this information and the fact that Canada relies heavily on international trade, being a smaller economy in comparison to the United States and Japan, it can be inferred that Canada exports, on a per capita basis, more than both Japan and the United States (Option C). This is due to Canada's need to engage in international trade to maximize its economic performance, which is different from the self-contained large economies of the United States and Japan that trade less per capita as they have less relative need for international trade to sustain their economic activities.
