Final answer:
Christopher Columbus’s voyage indicated a possible sea route to Asia is false. The correct option is false.
Step-by-step explanation:
The statement that Christopher Columbus's voyage indicated a possible sea route to Asia is false. Although Columbus himself believed until his death that he had found a new route to Asia, he had actually encountered a previously unknown land mass, now known as the Americas.
European monarchs were interested in Columbus's proposal as a response to increasing difficulties in land-based trade routes to Asia, following the collapse of the Mongol Empire and the rise of Ottoman control over existing routes.
Columbus's mathematical miscalculations and his misunderstanding of the Earth's size led him to assert he had reached Asia when he landed on an island in the Bahamas and went on to explore Hispaniola, calling the natives there "Indios."
The truth about the vastness of the Americas and the separate oceanic identity of the Pacific was confirmed later through the voyages of others like Ferdinand Magellan, who managed to circumnavigate the globe - indicating clearly that Columbus had not found a new route to Asia, but rather had stumbled upon the New World.
The correct option is false.
