Final answer:
Trade among developing nations is indeed growing quickly, as evidenced by the success stories of countries that engage actively in the global market and reduce trade barriers.
Step-by-step explanation:
The statement that trade among developing nations is growing quickly can be considered true. The pattern of increased trade activity is apparent when looking at the economic success stories of nations such as China and India, which have significantly benefited from participating in global markets. This activity is consistent with the historical evidence that shows countries thriving economically when they engage in international trade and reduce trade barriers. Similarly, smaller economies learn the importance of being part of the global trade network to achieve higher standards of living, as isolation has not led to economic prosperity in world history.
