Option 1: "Potatoes are the primary source of food in many parts of the world."

This aligns with the overall theme of the text, which emphasizes the importance of potatoes in various diets.
Option 2: "The potato is a root vegetable native to Ireland."
Explanation: This option is incorrect because the text specifies that potatoes grew wild in Peru, not Ireland. While they are significant in Irish cuisine, they are not native to Ireland, making this statement factually inaccurate.
