Question

1. describe the reason why native americans were particularly vulnerable to diseases brought by colonizers.

native americans had stronger immune systems.
native americans had access to modern medicine.
native americans were already exposed to similar diseases.
native americans had no immunity to these illnesses.

Explanation:

To determine why Native Americans were vulnerable to diseases from colonizers, we analyze the options:

• "Native Americans had stronger immune systems" is incorrect as vulnerability implies weaker immunity.
• "Native Americans had access to modern medicine" is wrong because modern medicine didn’t exist then for them.
• "Native Americans were already exposed to similar diseases" is incorrect; they lacked prior exposure.
• "Native Americans had no immunity to these illnesses" is correct. Colonizers brought diseases (like smallpox) that Native Americans had never encountered, so their immune systems had no defenses (no antibodies or prior exposure - induced immunity) against these new pathogens.

Answer:

The correct option is: "Native Americans had no immunity to these illnesses." (The option with this text, likely the third or fourth circular option in the image, depending on labeling, but based on content, the one stating Native Americans had no immunity to these illnesses.)
