3. How does a winnowing basket work?When the basket is tossed, the lighter chaff is carried away by air, while the heavier grain falls back to the ground.
4. Why was the winnowing basket important for early farmers?It helped clean the grain so it could be milled, cooked, and stored, making food safer and more reliable.
