Step-by-step explanation:
The main idea of the last paragraph is that Columbus had erroneous views about his voyage and the lands he discovered. He believed he had reached Asia, but instead, he landed in the Bahamas and later Hispaniola. Columbus's perception of the world and his belief that the earth was smaller than its actual size influenced his thinking. This misconception led to the naming of native Taínos as 'Indios' and the use of the term 'Indian' for native people of the New World.
