Answer:
Option: True
Step-by-step explanation:
When the European (Spanish) reached the New World, they not only bring soldiers but diseases also. The Native Americans not being immune to European diseases like smallpox and measles, died which finished the entire native population along with their civilization.
Diseases were already spread in the Inca Empire before Francisco Pizarro defeated them. In 1528, due to contact with the European, the Inca Emperor Huayna Capac died from smallpox. It would be true to say that the diseases helped the Spanish conquistador and explorers to conquer the land in America.
