Answer 2

The process of separation of grain from the chaff after harvesting is known as threshing.

Explanation:

• Threshing can also be known as "sieving" or “winnowing”.  

• Threshing was a time-consuming and usually laborious task, and wheat bushels took about an hour.  

• Today, threshing in development areas is mostly done mechanically, most often by combining harvesting, threshing, and harvesting grains while in the field.  

• Grains can be stored in barns or silos.

• Examples are paddy (rice) and wheat.
