What is a tractor used for in agriculture?

Correct answer: For ploughing and other heavy farm work

The direct answer is A: for ploughing and other heavy farm work. A tractor is a powerful agricultural machine. It can pull a plough, cultivator, trailer or other equipment, helping farmers prepare soil, transport materials and perform heavy work faster than human or animal labour alone. The reasoning is: the engine supplies power, the tractor pulls an attached implement, and the implement loosens or turns soil or carries a load. Option A is correct because ploughing and similar demanding tasks are important uses of tractors. Option B, cooking grains, requires a kitchen or processing equipment, not a tractor. Option C, washing clothes, requires washing tools and water arrangements, not farm machinery. Option D, eating soil, is impossible and is not a human or machine activity. Using machines to make farm work quicker and easier is called mechanisation. Remember: tractor means power for field work, especially ploughing and transport.
