Question

‘Combine’ is used in which of the following?
A.Threshing
B.Handpicking
C.Sieving
D.Filtration

Answer 1

Combine is a machine used nowadays by farmers for harvesting crops. As the name suggests combine is the machine that combines the four operations- reaping, threshing, gathering, and winnowing and makes it easier for the farmers to harvest the crops in a single process.

Complete answer:
The combine is not any method but it is simply a versatile machine that is designed to efficiently harvest several grain crops. The name combine is derived from four separate harvesting operations—reaping, threshing, gathering, and winnowing—that are combined into a single process.

And therefore the correct option is A. threshing.

A combine machine is considered a very good option for farmers when it comes to harvesting. In design, the combine harvester machine or simply combine is essentially a binder-type cutting device that delivers the grain to a threshing machine modified to work as it moves across the field. The combine machine is a very good machine for harvesting crops. It also lets the crop in the field be exposed to the sun for drying, storing the harvested crop in stacks or piles. The machine is specially used for the crops to collect seeds or edible parts placed at the top of the grains and discarding or leaving the below or inedible or chaff part in the field. A combine is mostly used for crops like Paddy, oats, wheat, barley, rye, corn, sorghum, sunflower, linseed, canola, and soybean.

Note:
Combine harvesters are one of the most economically important labor-saving inventions, significantly reducing the fraction of the population engaged in agriculture. It is a key invention that saves cost and time for farmers as it simply combines the major harvesting operations into a single process.
