Question

question 1-17
which of the following was not a result of the columbian exchange?
○ horses and cows were brought to the old world from the new world.
○ old world diseases killed millions in the new world.
○ new world crops caused population explosions in europe, asia & africa.
○ parts of west africa were virtually depopulated of males.

Explanation:

To solve this, we analyze each option in the context of the Columbian Exchange:

• Option 1 (Horses and cows...): Horses and cows were Old World (Eurasia/Africa) animals brought to the New World (Americas), not the other way around. So this is not a result of the Columbian Exchange.
• Option 2 (Old World diseases...): Old World diseases (e.g., smallpox) devastated New World populations—this is a key result of the exchange.
• Option 3 (New World crops...): New World crops (e.g., potatoes, corn) led to population growth in the Old World—this is a result of the exchange.
• Option 4 (Parts of West Africa...): The trans - Atlantic slave trade (related to the Columbian Exchange) depopulated West Africa of males—this is a result of the exchange.

Answer:

A. Horses and cows were brought to the Old World from the New World.
