Question 2

Potatoes were introduced to Europe and became a staple crop. They are highly nutritious and can be grown in various climates, which supported a larger population, leading to a population boom. Chocolate was more of a luxury item, corn and tomatoes, while important, did not have the same impact on population growth as potatoes.

Native Americans had no prior exposure to European diseases like smallpox, measles, etc. So when Europeans arrived, these diseases spread rapidly among Native Americans, who had no immunity, causing a large number of deaths. Disliking food, moving to Europe, or running out of corn are not the main reasons for the high mortality rate.

Answer:

Potatoes
