Detailed Solution

The above statement is true.
The wheat grains from the husk can be separated using the method of winnowing. The process of separating chaff or husk from the grains by wind or by blowing air is known as winnowing. The wind helps in separating the heavier components from the lighter components. For example, when the wheat grains are dropped from a raised platform, the lighter particles, which are rice flakes, will be blown away by the wind, and the wheat grains will fall and form a heap near the platform. Thus, the wheat grains get separated from the rice flakes.
