The Three Sisters refers to which crops?

• A. Rice, Wheat, Barley
• B. Corn, Beans, and Squash
• C. Maize only
• D. Potatoes, Tomatoes, and Peppers

Answer: (B)

The main idea here is how a traditional farming method uses companion planting to make a small plot productive. The Three Sisters refers to growing maize (corn), beans, and squash together. Each crop supports the others: corn provides a tall framework for beans to climb, beans fix nitrogen in the soil to nourish all three crops, and squash spreads along the ground with large leaves that shade the soil, reducing weeds and retaining moisture. Together, they offer a balanced, nutritious system—corn for energy, beans for protein, and squash for vitamins and minerals. This trio is a well-known farming practice among Indigenous peoples in North America, illustrating how crops can be grown in harmony rather than in isolation. The other options don’t form this famous trio or the same interdependent growing pattern.
