Final answer:
Marco Polo develops his ideas about Kublai Khan by describing the splendors of the Khan's palace and the city of Kinsay. Hernán Cortés develops his ideas about the idols by recounting his encounters with the indigenous people of Mexico.
Step-by-step explanation:
In the "Second Letter to Charles V," Marco Polo develops his ideas about Kublai Khan by describing the splendors of the Khan's palace and the city of Kinsay (Hangzhou). He highlights the wealth and grandeur of the Mongol empire, mentioning the use of paper money and a Chinese form of pasta. He also talks about his role as an official at the Khan's court and his travels to lands never before seen by Europeans.
In the Travels of Marco Polo, Hernán Cortés develops his ideas about the idols by recounting his encounters with the indigenous people of Mexico. He describes their religious practices, including their worship of idols and human sacrifices. Cortés portrays these practices as pagan and sinful, contrasting them with the Christian faith. He seeks to justify his conquest of Mexico as a mission to convert the natives to Christianity.
