Explanation:

Question 4

Maize (corn) was domesticated around 9000 years ago, so the statement is true.

The earliest domesticated food plants date to around 10,000 years ago (or 10,000 BCE, but in terms of years ago from present, 10,000 years ago is accurate). 2100 years ago is too recent, 20,000 BCE is too early, and 10,000 BCE is equivalent to 12,000 years ago approximately, so 10,000 years ago is correct.

Indigenous people of Central and North America relied chiefly on maize (corn) for food. Potatoes are from South America, bananas from tropical regions (not primary for N/C America), wheat is from the Old World.

True
