Which machine is used to harvest grain?

• A. Combine
• B. Harvester
• C. Reaper
• D. Threshing machine

Answer: (A)

A machine for harvesting grain is the combine, short for a combine harvester. It’s designed to perform three steps in one pass: reaping (cutting the grain), threshing (separating the grain from the straw), and cleaning (winnowing the grain to remove chaff). This integration is why the combine is used for crops like wheat, oats, barley, and corn—it streamlines the entire harvest process.

A reaper only cuts the grain, a threshing machine only separates the grain from the stalks, and a harvester is a general term that doesn’t specify performing all these steps in one machine. The combine uniquely handles all stages in a single operation, making it the standard choice for grain harvest.
