Final answer:
Southeast Asia's economies would benefit most from improved maritime technologies due to the historical significance of sailing in the region, which is facilitated by monsoon winds and would enhance trade networks.
Step-by-step explanation:
Given the geographic location of Southeast Asia, economies there would benefit MOST from improved maritime technologies. This region's geography and climate have historically made sailing an efficient means of transport and trade. With the help of monsoon winds, merchants have been able to easily conduct trade across the Indian Ocean, connecting Southeast Asia with a vast marketplace of ideas, goods, and cultures. Therefore, investments in maritime technologies would likely enable even more efficient and expanded trade in today's global economy, tying into the assessment of how changes in resources and infrastructure affect the location and patterns of economic activities (WG.11C).
