Q1. [3] medium thorough-understanding

Model Answer

The single most devastating weapon the Spanish conquerors carried was germs, particularly those causing smallpox. Indigenous Americans were so vulnerable because of their long isolation from the rest of the world — they had no prior exposure to these diseases and therefore had no immunity against them. Smallpox proved especially deadly as it spread deep into the continent ahead of the Europeans themselves, killing and decimating whole communities before conquerors physically arrived, thereby weakening resistance and paving the way for conquest.
