Solution:The above statement is true.
Since Native Americans were unaffected by settlers and colonial illnesses, the global transmission of disease in the pre-modern world helped colonise the Americas. Europeans were more or less immune to smallpox, but Native Americans, who had been isolated from the rest of the world for millions of years, had no way to fight back. These bacteria killed and wiped out the entire community, paving the way for foreign domination. Weapons and soldiers could be destroyed or captured, but they could not fight the disease. Good firepower was not the only reason for Europe's conquest of America. Traditional military weapons were not the mighty weapons of the Spanish conquerors. The most potent weapon a person had was jewel-like smallpox. Smallpox was a particularly dangerous murderer.
