What was one major consequence of the rise of empires such as Rome and Han China?

The rise of powerful empires like Rome and Han China significantly enhanced cultural exchanges and trade across vast regions, which is why this choice is accurate. The expansion of these empires facilitated not only the movement of goods but also the sharing of ideas, technologies, and cultural practices among diverse peoples. For instance, the Silk Road, which connected China to the Mediterranean, became a crucial trade route during the Han Dynasty, enabling the flow of silk, spices, and other commodities, alongside philosophical and scientific insights.

Moreover, Rome's extensive network of roads and maritime routes allowed for efficient trade and cultural interactions across Europe, North Africa, and parts of the Middle East. This interconnectivity helped to create a more integrated world where different cultures could influence one another, leading to advancements in areas such as art, architecture, and religion. Ultimately, these exchanges contributed to the development of a more cosmopolitan civilization and laid the groundwork for later global interactions.
